pollination

the transfer of pollen from male to female reproductive organs in higher plants, for example, microsporangium to ovule in GYMNOSPERMS, and anther to stigma in ANGIOSPERMS. In flowering plants the flowers show a strong link between structure and the method of pollination (see ANEMOPHILY, ENTOMOPHILY).

Many angiosperms carry out CROSS-POLLINATION. Some of these types, such as brassicas, have SELF-INCOMPATIBILITY systems to prevent self-pollination. Self-pollination, however, is common in certain plants, such as groundsel or chickweed.

The present study investigated the impact of drought stress (control and drought) around pollination and foliar sprays of potassium (K; 0, 1, 2 and 5% K2SO4) on leaf K concentrations and yield determinants of maize under greenhouse and field conditions.
Using bud pollinations to avoid self-incompatibility: implications from studies of three mustards.
The convergent evolution of some floral features across distantly related taxa has led to the concept of "pollination syndromes," suites of floral characteristics that indicate a plant species' primary or most effective pollinator (e.g., bees, birds, moths, bats, etc.) (Faegri and van der Pijl, 1979).
Pollinations restricted with paper and with tulle produced fruits with heavier seeds and a larger amount of seeds in the fruit (Table 3).
To further investigate the expression patterns after compatible pollination and incompatible pollination and compare their difference, controlled pollinations, that is, "Hongpisu" x "Hongpisu" and "Hongpisu" x "Jinhua," were conducted.
Pollination is significantly affected by different factors, such as pollen efficiency, which might be related to chromosome translocations that affect fertility and/or growth rate of pollen tubes in the ovaries of triploid cultivars (SHEPHERD et al., 1987a, 1987b).
Fifty mature buds, five each from ten inflorescences on five trees were bagged a day before anthesis without manual self pollination to know whether fruit set occurs through autogamy.
Longevity of flowers may be influenced by timing of pollination, mating system, and growth form (Devlin and Stephenson, 1984; primack, 1985; stratton, 1989; schoen and Ashman, 1995; clayton and Aizen, 1996).
Early fruit abortion is a major mortality factor to the yucca moth's progeny, and the female can increase retention by providing high-quality pollinations. Nonetheless, individual pollen loads are usually below levels that provide higher probability of retention, and commonly observed geitonogamous pollinations also appear to conflict with expected strong selection on moths to provide pollinations that give high retention probability.
However, lack of pollination of commercial crops is an issue of agricultural, not environmental importance.
arifolia, which were commonly the centermost ones in the coe-nanthia, exhibited a peculiar feature after pollination, namely the return of the style into the alveolus, which rendered them immersed again (Fig.
