【摘要】 在水富县同一纬度不同海拔的2个试验点,对4个不育系和2个恢复系以及组配所得到的8个杂交水稻新组合,杂交水稻对照品种"II优838",通过人工控光进行光温反应特性研究。结果表明,供试材料中感光性弱、感光性弱、短日高温生育期长的品种有11份,感光性中等、感温性弱、短日高温生育期长的品种有2份,感光性弱、感温性中等、短日高温生育期长的品种有1份,感温性中等、感光性中等、短日高温生育期长的品种有1份。更多还原

【Abstract】 The photoperiod and temperature characteristics of 15 pieces of material were studied by means of light controlled artificially at two experiment sites which were located in same latitude and different elevations. The result showed that 11 pieces belonged to the group of low photonasty,low temperature sensibility and long growth period in the condition of short daylight and high temperature; 2 pieces were middle photonasty,low temperature sensitivity and long growth period; 1 piece was low photonasty,middle temperature sensitivity and long growth period; 1 piece was middle photonasty,middle temperature sensitivity and long growth period.更多还原
