Use of controlled pollination is generally confined to various types of research . 控制授粉的应用，一般只限于干不同的研究工作。
Only a few forest tree species can develop viable seed from unpollinated ovules . 只有少数林木可以从未授粉的胚珠发育成有活力的种子。
Supplemental mass-pollination can substantially increase the seed yields in many cases . 在许多情况中，辅助混合授粉实际上可以提高种子产量。
It is wise to place cloth bags over the pollinated branches a month or two prior to harvest . 在收获前12月用布袋套在授粉的枝条上将是恰当的。
A compromise has to be made as to the choice of clones to be used as pollen parents . 对于用作授粉亲本的一些无性系的选择，不得不采用一种折衷办法。
The position of female inflorescences of trees in peripheral parts of the crown may also augment the probability of pollination . 乔木的雌花花序在树冠外层的位置也能增加授粉的机会。
Emasculation will probably be needed, and the pollen so obtained being used either in the pollen-mix or for dilution purpose . 或许需要去雄，如此获得的花粉可用于混合授粉或稀释授粉。
