采收时花序上花蕾发育程度越低,切花含糖量越低,瓶插时切花体内的糖消耗量越少,切花瓶插观赏品质越差。小花由绿蕾至盛开需吸收高于自身含糖量数倍的糖分。即使是开放期采收的切花,其自身含糖量也不能充分满足花序上花蕾继续生长发育的需要。
The lower the degree of flower bud development on the inflorescence, the lower the sugar content of cut flowers, the less the sugar consumption in cut flowers when bottle inserted, the worse the ornamental quality of cut vase insert. Flowers from green buds to bloom in need to absorb more sugar than its own sugar several times. Even cut flowers harvested during the open period, its own sugar content can not fully meet the inflorescence flower buds to continue the growth and development needs.
