【摘要】 以玉米杂交种农单5号和农大108为材料,采用玉米子粒离体培养的方法研究了不同温度处理对子粒发育的影响,并对子粒败育率、粒重、可溶性糖和淀粉含量进行了测定。结果表明,2个品种对温度影响表现出相同的趋势:与18℃、38℃相比,28℃下子粒发育最好,子粒败育率低、粒重高。在18℃和38℃下,子粒的可溶性糖含量高而淀粉含量低。28℃条件下较适合子粒的发育。更多还原

【Abstract】 The effects of temperature on kernel development were studied in vitro,with maize hybrids Nongdan 5 and Nongda 108.The rate of kernel abortion,kernel weight,and the content of soluble sugar,starch were also measured.The result showed that the effects of temperature on 2 hybrids were showed the same trend: the rate of kernel abortion was lowest and kernel weight was highest at 28℃ compared with the 18℃ and 38℃.Content of soluble sugar was high and starch was low at both 18℃ and 38℃.Condition of 28℃ was most suit for kernel development.更多还原
