| 摘 要： | 以德国鸢尾‘Royal touch’为试验材料,研究了5种光周期对其花芽分化和光合作用的影响。结果表明:(1)短日照加速了植株花芽分化的进程,而长日照促进了单花序上花芽数目的增加;(2)长日照下植株单位叶面积的光合能力较强(;3)植株的花芽分化与其叶面积、叶干重、地上部分与地下部分的干重比值之间呈显著的正相关关系。这些结果说明了光周期对德国鸢尾‘Royal touch’花芽分化时间和数量的影响与光周期对其植株生物量和光合作用的影响有关。 |

| Abstract: | Iris germanica 'Royal touch' was used to investigate the effects of 5 different photoperiods on flower bud differentiation and photosynthesis.Short-day treatments accelerated the flower bud differentiation,whereas long-day treatments increased the numbers of the flower buds per inflorescence.The photosynthetic capacity per unit leaf area was higher in long-day treatments.Flower bud differentiation had a significantly positive correlation with leaf area,leaf dry weight,and the ratio of above: below ground biomass,respectively.These results suggested that effects of photoperiods on flower bud differentiation and numbers are related to plant biomass and photosynthesis. |
| Keywords: | Iris germanica Photoperiod Flower bud differentiation Photosynthesis Biomass |
