6-BA和保水剂对切花月季瓶插寿命的影响

The Effect of 6-BA and SAR on Vase-life of Cut Rose

初步探讨了6-BA和保水剂对月季切花的保鲜作用与生理生化基础,与对照(清水)相比,经10mg/L6-BA和10mg/L6-BA+0.3%保水剂处理的月季切花,花枝的保水能力提高,花枝硬挺,并延缓质膜相对透性的增加、蛋白质的降解及MDA的产生,从而延长月季切花的瓶插寿命(2～3d),但后者各项指标均优于前者,效果更佳.

This paper studies the effects of 6-BA and SAR on preserving freshness of cut rose and physiological and biochemical base . Compared with the contrast ( pure water ) 10mg/L 6-BA and 10mg/L 6-BA +0.3%SAR can improve the ability of preserving water of cut rose twigs and thus make them stiff and straight. Moreover 6-BA and SAR can delay the multiply of relative permeability of cell membrane , the degradation of protein and the production of MDA and thus lengthen the life span of cut twigs of cut rose in vase , every indexs of whose is superior to the cut twigs in ordinary water .
