Selfing is inhibited by genetic self incompatibility and also by the fact that within a single flower the stigma is receptive before the anthes are ready to shed pollen . 由于遺傳上的自交不親和性以及花中柱頭只能在花粉準備撒粉以前接受花粉,因而防止了自交。

The results from the pollen densitometers indicate the number of pollen grains sucked into a device per square millimeter of the aperture . 花粉顯像密度計的計算結果,可以表明每一平方毫米孔徑上吸入的花粉粒數。

The second step is to establish a series of pollen collecting stations on four transects running different directions from the source tree . 第二步是從離開夾源樹四個不同方向的斷面上建立一系列的花粉收集站。

A beekeeper, seeing the bee collect pollen from flowers and carry it to the hive, says that it exists to gather honey . 一個養蜂人看見蜜蜂從花里收集花粉,帶去蜂房,就說蜜蜂為了采蜜而存在。

When the same species occurs in the neighbourhood of an orchard, pollen will obviously infiltrate from the outside sources . 當種子園附近存在相同的樹種時,花粉就會明顯地從外部傳來。

Emasculation will probably be needed, and the pollen so obtained being used either in the pollen-mix or for dilution purpose . 或許需要去雄,如此獲得的花粉可用于混合授粉或稀釋授粉。

At first brown attributed the motion to a mobility possessed by the pollen grains by virtue of their animate nature . 起初,布朗把這種運動歸結為由花粉生物性質所決定的遷移過程。

It is necessary to cut entire branches, spread them on paper to dry, remove the branches and screen the pollen . 必須將整個枝條切取下來,鋪于紙上進行干躁,除去小枝并篩凈花粉。
