pollen incompatibility 中文意思是什麼

pollen incompatibility 解釋
花粉不親和性
  • pollen : n. 1. 【植物;植物學】花粉。2. 【蟲類】粉面。vt. 授粉給;傳粉給;用花粉掩蓋。
  • incompatibility : 不並存性
  1. However, only did a few pollen germinate in inter - specific hybridization between cerasus fruticosa and c. avian and many pollen tubes are crosswise on stigma and couldn " t penetrated into style. although a few pollen tubes entered, they couldn " t continue to grow due to accumulation of callosity in pollen tubes. in view of above - mentioned results, the irregular growth of pollen was the main reason to cause the incompatibility of distant hybridization between cerasus fruticosa and c. avium

    而草原櫻桃與歐洲甜櫻桃種間雜交授粉后花粉在柱頭上雖少量萌發,但花粉管在柱頭上橫向生長,或盤繞,扭曲不能伸入花柱;個別進入花柱的花粉管先端因沉積胼胝質而中途停止伸長未能進入子房到達胚珠,從而說明這種雜交授粉后花粉管的不正常行為是導致草原櫻桃與歐洲甜櫻桃遠緣雜交不親和的主要原因。
  2. 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.

    由於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。
  3. In sporophytically self - incompatible brassica, three s - linked genes, the pollen ligand scr, stigma receptor slg and srk, have been identified. in addition, four genes ( arc1, thl1, thl2 and mod ) that do not link to s locus have also been found, they are regarded as downstream protein factors of self - incompatibility ( si ) response, however, their biological function is not clear

    在孢子體型自交不親和的蕓薹屬中,已經鑒定出3個主要與s位點緊密連鎖的基因,花粉中的配體scr和柱頭中的受體slg與srk :另外鑒定出4個不與s位點連鎖的基因arc1 、 thl1 、 thl2和mod ,它們被認為是si反應的下游蛋白質因子,但是對它們的生物學功能了解的還比較少。
