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.
对种子败育的白皮黄瓜品种白玉(BY)和种子发育良好的青皮黄瓜品种青皮(QP)的雌雄配子发育阶段进行了组织形态学比较研究,结果发现,BY部分小孢子四分体之间相互粘连在一起,相互粘连的胼胝质壁水解形成复合小孢子四分体;在单核小孢子时期,有些小孢子壁皱缩,膜内陷,不规则;观察BY成熟胚囊发现,在胚囊中央有多个类极核,珠心组织细胞离散、变形,大孢子囊边缘不规则;BY在球形胚初期,胚乳发育异常,细胞提前液泡化,具玻璃质感,染色不明显,在显微镜下透光率强,并且胚乳细胞内含物提前降解,胚乳胞间质降解,随后胚乳细胞降解,只留下残迹,球形胚停止发育。
White cucumber is gradually favoured.
随着人们生活水平的不断提高，不但对黄瓜品质有更高的要求，也需要更多的花色品种，白皮黄瓜正逐渐受到人们的青睐。
