The comparative cytomorphology on the development of female and male gametophyte was studied between white cucumber-BY whose seeds are most abortive and green cucumber-QP whose seeds are most well-developed.
對種子敗育的白皮黃瓜品種白玉(BY)和種子發(fā)育良好的青皮黃瓜品種青皮(QP)的雌雄配子發(fā)育階段進(jìn)行了組織形態(tài)學(xué)比較研究,結(jié)果發(fā)現(xiàn),BY部分小孢子四分體之間相互粘連在一起,相互粘連的胼胝質(zhì)壁水解形成復(fù)合小孢子四分體;在單核小孢子時(shí)期,有些小孢子壁皺縮,膜內(nèi)陷,不規(guī)則;觀察BY成熟胚囊發(fā)現(xiàn),在胚囊中央有多個類極核,珠心組織細(xì)胞離散、變形,大孢子囊邊緣不規(guī)則;BY在球形胚初期,胚乳發(fā)育異常,細(xì)胞提前液泡化,具玻璃質(zhì)感,染色不明顯,在顯微鏡下透光率強(qiáng),并且胚乳細(xì)胞內(nèi)含物提前降解,胚乳胞間質(zhì)降解,隨后胚乳細(xì)胞降解,只留下殘跡,球形胚停止發(fā)育。
White cucumber is gradually favoured.
隨著人們生活水平的不斷提高，不但對黃瓜品質(zhì)有更高的要求，也需要更多的花色品種，白皮黃瓜正逐漸受到人們的青睞。
