Foliar Application of Potassium Sulfate Partially Alleviates Pre-anthesis Drought-induced Kernel Abortion in Maize. It is the most primitive type of pollination and mostly the plants produces unisexual flowers. 9.3 Method of Cross Pollination 1. For an anemophilous species the maize pollen is very large with a grain size of 90– 125 μm and a weight of about 247×10 −9 g. As a result, the pollen grains have a high terminal velocity of 20 cm s −1 , a settling velocity of 40 cm s −1 and a deposition coefficient ( d ) of 0.20 ( Emberlin et al., 1999 ). Other common anemophilous plants are oaks, sweet chestnuts, cereal crops, alders and members of the family Juglandaceae (hickory or walnut family). The leafy stalk of the plant produces pollen inflorescences and separate ovuliferous inflorescences called ears that yield kernels or seeds, which are fruits. Anemophily (Wind pollination): (Gk, anemos = wind and philein = to love) This is a mode of pollination or transfer of pollengrains from anther to stigma via the agency of wind. Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind. Stigma of anemophilous flowers is feathery. ... Anemophilous flowers ... 1. ... in which case the plant is described as anemophilous (literally wind-loving). Ans: Anaemophily is the pollination which is caused by wind. Firmly rooted in soil, over the course of their evolution plants have had to develop biological mechanisms for feeding and reproduction without moving, a characteristic that differentiates them from animals which on the contrary move around to procure food and to mate. Anemophily (Gk. Paddy, Wheat, Maize. Anemophilous flowers are characterized by the given adaptations: 1. entomophilous - of flowering plants (especially orchids etc) that are pollinated by insects Explain how some plants are adapted for achieving pollination … C) Malacophilous done clear. Pollination, a perfect alliance between plants and animals. Each pollen grain is haploid: it has half of the DNA (genetic information) that is needed to make a new plant. Adj. Maize (just called corn in some parts of the world, like New Zealand) is pollinated by wind. Anemophily is also found in all Gymnosperm. A. Cleistogamous. (iv) In maize, the pollination is brought about by insects. Almost all gymnosperms are anemophilous, as are many plants in the order Poales, including grasses, sedges, and rushes. In the investigated biological research department, maize pollination took place in a greenhouse within 3 major steps: 1. There are three categories of zoophily. Entomophilous pollen - collected by insects during insect pollination. (ii) Cross-pollination always occurs in unisexual flowers. Such as cereal plants: Maize, wheat, etc. ... maize pollination took place in a greenhouse within 3 major steps: 1. Pollen is an important food source for bees, providing protein in the diet of adult bees, and is essential for weight gain in the newly-hatched bee larvae. Pollination through wind: In many plants Pollination occurs through wind.Flowers in which pollination occur, through wind are known as Anemophilous flowers. Maize pollen is anemophilous (dispersed by wind) and most pollen grains fall within a few meters of the tassel because of its high settling velocity. 2.19): It is a mode of cross pollination or transfer of pollen grains from a mature anther to the stigma of a pistil which is accomplished through the agency of wind, e.g., Coconut Palm, Date Palm, Maize, many grasses, Cannabis. 2.

Advantages and Disadvantages of Cross-Pollination 3. The honey bee dance language, used to recruit nestmates to food sources, is regarded by many as one of the most intriguing communication systems in animals. Stamens have long filaments and are exposed. Coconut, palm, maize, grasses and all gymnosperms are the best examples of wind-pollinated plants. D. Hydrophilous. Pollination is part of sexual reproduction in plants.It describes how the pollen grains get to the female parts of a plant. Pollen grains, which contain the male gametes, need to get to where the female gamete(s) are.. What happens is basically the same as sexual reproduction in animals. Maize pollen is anemophilous (dispersed by wind) and most pollen grains fall within a few meters of the tassel because of its high settling velocity. Examples of anemophilous plants are coconut, palm, maize etc. Maize (/ m eɪ z / MAYZ; Zea mays subsp. (2) Pollination through the wind: Wind is another good agent of pollination. # Example of plants pollinating by anemophily - grasses ; maize; cannabis; Thanks dear. Ans: Fig. Distinct plant lineages often have convergent floral traits called pollination syndromes which are thought to have evolved to increase the efficiency of particular types of pollination vectors (Faegri and Pijl, 1979).
