  • Milkweed Seeds October 2010. Eastern Ontario. Asclepias L. the milkweeds, is a genus of herbaceous perennial, dicotyledonous plants that contains over 140 known species. It previously belonged to the family Asclepiadaceae, but this is now classified as the subfamily Asclepiadoideae of the dogbane family Apocynaceae. Milkweed is named for its milky juice, which contains alkaloids, latex, and several other complex compounds including cardenolides. Some species are known to be toxic. Carl Linnaeus named the genus after Asclepius, the Greek god of healing, because of the many folk-medicinal uses for the milkweed plants. Pollination in this genus is accomplished in an unusual manner. Pollen is grouped into complex structures called pollinia, rather than being individual grains or tetrads, as is typical for most plants. The feet or mouthparts of flower visiting insects such as bees, wasps and butterflies, slip into one of the five slits in each flower formed by adjacent anthers. The bases of the pollinia then mechanically attach to the insect, pulling a pair of pollen sacs free when the pollinator flies off. Pollination is effected by the reverse procedure in which one of the pollinia becomes trapped within the anther slit. Asclepias species produce their seeds in follicles. The seeds, which are arranged in overlapping rows, have white silky filament-like hairs known as pappus, silk, or floss. The follicles ripen and split open and the seeds, each carried by several dried pappus, are blown by ...

  • Loud Buzzing Bumblebee Works a Champlain Rose A Bumblebee working the roses in our back yard Toronto, Ontario June 5, 2010 One of our rose bushes swarms with bees and other insects when it's in bloom, mainly in late May and early June. It's a Champlain rose that's about six years old; a Martin Frobisher rose right beside is more fragrant to the human nose, but doesn't draw nearly as many insects. Both roses are examples of the Explorer series developed by Dr. Felicitas Svejda at the Experimental Farm in Ottawa back in the sixties. The bumblebees are the most obvious and the easiest to film, but there are also honey bees and at least two other types (including wasps I think). There are also flies and various other insects, including one that looks like a tiny bee (but probably isn't). This video only follows a single bumblebee. The bee has two distinctly different types of buzz: one while flying and one while harvesting. The latter is quite loud. I originally thought the sound was from its wings striking the inside of the flower, but they are clearly at rest. According to Wikipedia, "The sound is actually the result of the bee vibrating its flight muscles, and this can be achieved while the muscles are decoupled from the wings." This may be partly to keep the flight muscles warmed up, but it may primarily be to shake more pollen loose: "Sonication or buzz pollination is a technique used by some bees to release pollen... bumblebees and some species of solitary bees are able to grab onto the flower and move their flight ...
  • Joseph Philpot - Devotional - December 31 December 31 "All flesh is as grass, and all the glory of man as the flower of grass. The grass withers, and the flower thereof falls away; but the word of the Lord endures forever. And this is the word which by the gospel is preached unto you." 1 Peter 1:24, 25 All flesh, and everything that springs from the flesh, and is connected with the flesh, is as grass, which, for a time, looks green and flourishing, but touched with the mower's scythe, or scorched by the midday sun, soon withers and fades away. Such is all flesh, without exception, from the highest to the lowest. As in nature, some grass grows thicker and longer than others; and makes, for a while, a brighter show, yet the scythe makes no distinction between the light crop and the heavy--so the scythe of death mows down with equal sweep the rich and the poor, and lays in one common grave all the children of men. You have seen sometimes in the early spring the grass in flower, and you have noticed those little yellowish "anthers," as they are termed, which tremble at every breeze. This is "the flower of grass;" and though so inconspicuous as almost to escape observation, yet as much its flower as the tulip or the rose is the flower of the plant which bears each. Now, as the grass withers, so the flower thereof falls away. It never had, at its best state, much permanency or strength of endurance, for it hung as by a thread, and it required but a little gust of wind to blow it away, and make it as though it never had ...

  • Eggplant growing. 1st Chapter The aubergine is a vegetable that belongs to the solanaceous or potato family, and which is known scientifically as Solanum melongena. It is an herbaceous plant although the stems, with their lignified woody tissue tend to make it resemble a small tree or bush. It is cultivated as an annual. The aubergine plant possesses a very strong deep root system. The stems are strong, hairy and t*** with a determined growth rate when referring to creeping shoots or an indefinite growth rate when talking about straight, erect stems. The main stem includes short internodes which fork out into secondary stems, which then divide at the leaf axils. The leaves are positioned alternately along the stem. They have a long stalk and are large, complete and oval in shape with t*** nerves. The underneath part of the leaves are covered with a greyish down. The flowers tend to droop and can appear either by themselves or in clusters of 3 to 5 flowers. They possess between 5 and 7 green sepals and the same number of elongated violet petals. The stamens have highly developed anthers which are yellow in colour and are situated under the stigma, which makes direct fertilization difficult. The fruit is an egg-shaped or bulbous berry which is black, purple, white or white-tinged purple or green with small yellow seeds. The aubergine requires a warm dry climate which is why it is considered to be one of the most demanding crops with regard to heat. It is a plant that thrives in high temperatures as ...
  • Hybridizing (pollinating) Daylilies in Your Garden Hybridizing the Daylilies in your garden is really easy and rewarding. The two parts you need to be familiar with are the anthers (male part of the flower) where the pollen is stored in the pollen sacks. The second part is the stigma, the tip of the female part of the flower. The easiest way to do is just to take an Anther and brush the pollen onto the stigma to pollinate the flower. You'll know if your attempt to pollinate the bloom was successful because it will develop a seed pod. Know you know how to hybridize and pollinate a daylily in your garden.

  • A fly feeds by sponging, then a bee pollinates a rose Some flies (order Diptera) have "sponging-sucking" mouth parts that moisten the substrate upon which they are feeding, and then sip up whatever has been dissolved. Here such a fly is finding something (what, I wonder?) on the petals and anthers of pasture rose (Rosa setigera). Next, a halictid bee arrives, slamming into, and grabbing, the central column of stigmas, no doubt effecting pollination. This occurred during the morning of June 22, at the Killdeer Plains wildlife Area in Wyandot County, Ohio, USA.

  • Shabnam Jabbari - Botany 2010 Flower Color Variability and Mixed Mating in the Protandrous Herb Saponaria officinalis (L. Caryophyllaceae). Co-author: Sandra L. Davis The perennial herb Saponaria officinalis is protandrous; within a flower, anthers dehisce before stigmas are receptive. Theory predicts this type of breeding system may have evolved to prevent self-fertilization and inbreeding depression. However, overlap between gender stages may allow for self-fertilization, resulting in a mixed mating system. The high frequency of mixed mating systems found in nature is intriguing, as theoretical models have predict plants will evolve to complete outcrossing or selfing. However, a mixed mating system in which selfing is delayed until opportunities for outcrossing have passed, provides the genetic benefits of outcrossing and the reproductive assurance of selfing. Prior studies have shown that pollinators are important in the reproduction of S. officinalis but flowers may still self-fertilize. Flowers of S. officinalis vary from white to pink; corresponding with the gender development of the flower. Color variability may affect pollinator visitation and preference. Therefore, to understand the evolution of mixed mating in S. officinalis, it is necessary to understand the interaction between these variables. Flower color may be a genetically determined trait and differ between populations. In addition, it is believed that sun exposure has an effect on the concentration of the anthocyanin. In this study ...

  • Gary Coté - Botany 2010 Microscopic Crystals in Aroid Flowers: A Role in Gamete Protection? Many plants have idioblast cells which produce crystals of calcium oxalate. Crystal idioblasts are well known in the vegetative tissues of species in the Araceae. Many aroid species have a type of crystal idioblast, termed the biforine, which is able to forcibly expel the crystals. It has often been proposed that these crystals, particularly those in biforines, might play a role in defending against herbivory. If this is true we would hypothesize that crystals would be abundant in reproductive tissues, arrayed so as to protect the pollen and ovules without interfering with pollinators. To test this, we examined floral tissues from 21 aroid species in 12 tribes, collected from greenhouse material and from the wild in Connecticut and Virginia (USA) and French Guiana. These species represented a variety of pollination strategies, including bribing pollinators with edible sterile flowers (staminodia). Tepals, in those species which had them, always contained crystals. Crystals were common in gynoecial walls, but generally absent from the ovules themselves. Crystals were found the connectives and filaments of stamens, particularly in those species where stamens fuse into synandria. Dense strands of biforine-like cells were seen in synandria. However, crystals were rare to absent in anthers, except that species of Caladieae and Dieffenbachieae contain prismatic crystals among the pollen. The results are ...
  • Fruit and seed Dispersal Check us out at Seeds provide the vital genetic link and dispersal agent between successive generations of plants. Angiosperm seeds are produced and packaged in botanical structures called fruits which develop from the "female" pistils of flowers. Immature seeds (called ovules) each contain a minute, single-celled egg enclosed within a 7-celled embryo sac. The haploid (1n) egg is fertilized by a haploid (1n) sperm resulting in a diploid (2n) zygote that divides by mitosis into a minute, multicellular embryo within the developing seed. A second sperm unites with 2 haploid polar nuclei inside a binucleate cell called the endosperm mother cell which divides into a mass of nutritive tissue inside the seed. In most seeds the embryo is embedded in this endosperm tissue which provides sustenance to the embryo during germination. In exalbuminous seeds (found in many plants such as the legumes), the endosperm tissue is already absorbed by the time you examine a mature seed within the pod, and the 2 white fleshy halves in the seed are really the cotyledons (components of the embryo). The 2 sperm involved in the double fertilization process originated within the pollen tube that penetrated the embryo sac. The pollen grain (and pollen tube) come from the "male" organs (called anthers) on the same plant or different parental plants in a remarkable process known as pollination. Pollination is also accomplished by the wind (or water), and it may also involve insects ...
  • Hay Fever Hello and welcome to another Daily Dose of English. If my eyes look a little red today, and my voice sounds as if I have a cold, it's because it's hay fever season once again, and I suffer with this condition. Hay fever is also called allergic rhinitis or pollenosis. It is caused by an allergic reaction to pollen. Pollen is the stuff that plants make in order to reproduce. In this footage, you can see a bee carrying huge amounts of pollen in its pollen baskets on its legs. Bees use pollen to make honey. I use pollen to make my nose run, my eyes sore and provoke sneezing. Luckily, I suffer from seasonal hay fever. This means that I am only affected during a few weeks when certain plants are producing pollen in large amounts. That time is now. Here is an image of pollen grains. The image is magnified some x500, so the bean shaped grain in the bottom left corner is about 50 μm long. This pollen comes from a variety of common European plants. They include the sunflower (Helianthus annuus), morning glory (Ipomoea purpurea), hollyhock (Sildalcea malviflora), lily (Lilium auratum), primrose (Oenothera fruticosa) and castor bean (Ricinus communis). The picture was taken with an electron microscope at the Dartmouth Electron Microscope Facility in the UK. To show you the size of the pollen grains, here is a picture of a flower that I took clearly showing the pollen grains on the flower's stamens and anthers. While beautiful to look at, the grains of pollen ...
