摘　　要：荷花催花过程中不同生长发育阶段对有效积温的需求不同。通过对22个品种进行试验,结果表明:荷花的不同品种之间,同一品种的不同发育阶段对有效积温的要求不同。现蕾期所需要的有效积温最高,占总有效积温的1/2左右。说明现蕾透色期是生长发育的关键时期。其中品种‘粉红芽’、‘春不老’前期生长所需有效积温少,较早达到现蕾期,后期需要有效积温多,观赏期长,是催花的理想品种。The differently effectively accumulative temperature were investigated during the differently growing developmen- tal phase in flower forcing of Nelumbo nucifera. The results showed that the effectively accumulative temperature was the highest during squaring period, which accounted for almost 1/2 of the total effectively accumulative temperature. Squaring through color period was the critical period in the growth and development stage. Early growth of varieties ＇ Feuhongya＇ and ＇ Chunbulao＇ required lower effectively accumulated temperature to reach the bud stage earlier, late stage required higher effectively accumulated temperature to reach long viewing period, these two varieties are the ideal varieties of flower induction.
