When pollen germinates on a stigma the growing pollen tubes deposit callose as small plugs, but if the plant is self-incompatible, tubes from its own pollen will deposit more callose, which then blocks the tube, preventing fertilization.
当花粉在柱头上萌发时,生长的花粉管产生少量胼胝质,但如果该植物是自交不亲和的,那么花粉管将产生比较多的胼胝质,可以阻塞花粉管来阻止受精。

Sometimes, a few of pollen tubles could enter into styles through stigmas, but abnormal callose could deposit in the tubes.
结果表明,诸葛菜花粉很难在3种类型油菜的柱头上黏附和萌发,同时在花粉黏附的部位及其附近柱头乳突细胞内产生大量胼胝质;萌发的少量花粉粒,其花粉管生长迟缓,且发生严重扭曲、肿胀等畸形现象,从而导致其进入柱头也比较困难;少数花粉管能穿过柱头进入花柱,但时常有异常胼胝质沉积在花粉管中。

The results indicated that the high level density functional theory calculations can be used to predict the 13C chemical shifts of the modified nanotubes. The calculated results also provided the characteristic chemical shifts values of nitrene (superscript -), carbene (superscript -) and 1,2- and 1, 4-fluorinated nanotubes, which would be helpful for experimental spectrogram assignments. Combined with NMR experiments, these predicted characteristic chemical shifts can be further used to monitor the addition mechanism and the extent of surface modifications on nanotubes.
研究表明高精度的密度泛函理论计算能够用来预测纳米管的13C化学位移,理论研究的结果揭示了氮烯、卡宾以及1,2和1,4氟化的单壁纳米管的若干13C信号特征化学位移值,为实验NMR谱图的归属提供了一定的依据,并且可通过与实验相结合来监测表面官能化碳纳米管加成反应是否发生以及确认其加成方式。
