进行番茄杂交制种,常因授粉时的天气情况和所选择的母本花发育期不同,而使座果率受到很大影响。为了使番茄杂交制种取得良好效果,1976年我们选择了几种对杂交座果可能有影响的天气(如不同气温,有风和无风等)条件及不同部位的花穗,进 For tomato hybrid seed production, often due to pollination when the weather conditions and the selected mother flower development period is different, so that the fruit rate has been greatly affected. In order to achieve good results in hybrid tomato seed production in 1976, we have selected several conditions may affect the fruit of the hybrid fruit (such as different temperatures, wind and no wind, etc.) and different parts of the flower spike, into
