Abstract

Flower bud dormancy in azalea (Rhododendron simsii) is broken by artificial cold treatment and this will have its consequences on carbon reserves and photosynthesis. The effect of cold storage at 7 °C on carbohydrate and starch content in leaves and flower buds of an early ('Nordlicht') and semi-early ('M. Marie) flowering cultivar was quantified. Carbon loss due to respiration was lowest for 'M. Marie'. Photosynthetic measurements on 'Nordlicht' showed that photosynthesis 3 days after cold treatment (plants ready to flower) was improved compared to before cold treatment (plants with dormant flower buds).

摘要

杜鹃（映山红）的花芽休眠通过人工冷藏处理得以打破，这会对碳储备和光合作用产生影响。对一种早花品种（‘诺德licht’）和半早花品种（‘M. 玛丽’）的叶片和花芽在7°C下冷藏对碳水化合物和淀粉含量的影响进行了量化。‘M. 玛丽’因呼吸作用导致的碳损失最低。对‘诺德licht’的光合测量表明，与冷藏处理前（花芽休眠的植株）相比，冷藏处理3天后（准备开花的植株）光合作用有所改善。
