Plant species where normal mode of seed set is through a high degree of cross-pollination have characteristic reproductive features and population structure. Existence of self-sterility, [1] self-incompatibility, imperfect flowers, and mechanical obstructions make the plant dependent upon foreign pollen for normal seed set. Each plant receives ...
The pollinated but unripe seedpods look like oriental paper lanterns, less than 25 mm (1 in) across, pale green with purple highlights. The flowers of Hibiscus trionum can set seed via both outcrossing and self-pollination. During the first few hours after anthesis, the style and stigma are erect and receptive to receive pollen from other plants.
However, as opposed to 'complete' or 'absolute' SI, in CSI, self-pollination without the presence of competing cross pollen, results in successive fertilization and seed set; [45] in this way, reproduction is assured, even in the absence of cross-pollination. CSI acts, at least in some species, at the stage of pollen tube elongation, and leads ...
Plants which are not well-pollinated do not invest much in seed production, which can allow them to flower again in a short time. [9] This can re-synchronize individuals, because when they are well-pollinated and invest energy into seed production, they have limited resources to invest in flowering the following year. [citation needed]
A pollination network is a bipartite mutualistic network in which plants and ... (including plant-pollinator interactions and plant-seed disperser ...
As indoor farming expands, a number of new companies are cropping up to provide better data and monitoring tools for the businesses aimed at improving efficiencies and quality of indoor crops.
F2 hybrids, the result of self or cross-pollination of F1s, lack the consistency of F1s, though they may retain some desirable traits and can be produced more cheaply because hand pollination or other interventions are not required. Some seed companies offer F2 seed at less cost, particularly in bedding plants, where consistency is less ...
Pollination of fruit trees is required to produce seeds with surrounding fruit. It is the process of moving pollen from the anther to the stigma , either in the same flower or in another flower. Some tree species, including many fruit trees, do not produce fruit from self-pollination , so pollinizer trees are planted in orchards.
