本实验于1987年开始进行。到目前为止,已经完成了在模拟渍水条件下,子叶超微结构的镜检,并对生育期渍水的株体叶片也初步进行了电镜观察。 1987年选择生育期大豆品种绥农4和绥农5,宝交83-5029、嫩丰12,置于模拟渍水条件,在不同渍水时间内取其功能叶片;选择合丰25、绥农6大豆种子,置于渍水条件中,取其萌动期的子叶部分。经固定、脱水、包埋、切片、染色后,利用光学显微镜和电子显微镜观察。 The experiment began in 1987. So far, microscopic examination of the cotyledon ultrastructure has been completed under the simulated waterlogging condition, and the leaf of the plant body during the growth period has also been tentatively subjected to electron microscopy. In 1987, the selected growing soybean varieties Suinong 4 and Suinong 5, Baojiao 83-5029 and Nenfeng 12 were placed in simulated waterlogging condition, and their functional leaves were selected in different waterlogging times. Choosing Hefeng 25, Suinong 6 Soybean seeds, placed in waterlogging conditions, take the cotyledon part of the germination period. After fixation, dehydration, embedding, slicing, staining, the use of optical microscopy and electron microscopy.
