Abstract

Vase-life is a key factor for evaluating the post-harvest quality of cut flowers that determines their marketability. Chrysanthemum is one of the top most cut flowers sold in international flower markets. In the present study, trials were conducted to improve the postharvest life of chrysanthemum cut flowers using preservative solutions such as 5-sulfosalicylic acid (5-SSA) and aluminium sulphate (Al2(SO4)3) alone or in combination with 1.5 % sucrose. Treatments using 5-SSA (100 ppm and 150 ppm) or 200 ppm Al2(SO4)3 along with 1.5 % sucrose showed a significant increase in vase-life, fresh weight of the cut stems, vase solution uptake, membrane stability index of the petals and leaf chlorophyll as compared to other treatments. Among different vase solutions evaluated, T10 (200 ppm Al2(SO4)3 +1.5 % sucrose) gave maximum vase life of22.3 days, followed by T8 (5-SSA 150 ppm + 1.5 % sucrose) and T6 (100 ppm 5-SSA+ 1.5 % sucrose) treatments with 20.85 and 19.85 days respectively as compared to 17.84 days in control. High concentrations of both the chemicals (5-SSA and Al2(SO4)3) without sucrose showed toxicity symptoms.

5-磺基水杨酸和硫酸铝对菊花切花衰老的调控作用

花瓶寿命是评价采收后切花质量的关键因素，决定了切花的适销性。菊花是国际花卉市场上最畅销的切花之一。本研究采用5-磺基水杨酸(5-SSA)和硫酸铝(Al2(SO4)3)单独或与1.5%蔗糖联合使用的防腐剂溶液，对菊花切花采后寿命进行了改善试验。与其他处理相比，5-SSA (100 ppm和150 ppm)或200 ppm Al2(SO4)3以及1.5%蔗糖处理显著增加了花瓶寿命、切茎鲜重、花瓶溶液吸收量、花瓣膜稳定性指数和叶片叶绿素。在不同的花瓶溶液中，T10 (200ppm Al2(SO4)3 + 1.5%蔗糖)的最大花瓶寿命为22.3天，其次是T8 (150ppm 5-SSA+ 1.5%蔗糖)和T6 (100ppm 5-SSA+ 1.5%蔗糖)处理，分别为20.85和19.85天，而对照组为17.84天。不含蔗糖的高浓度化学物质(5-SSA和Al2(SO4)3)均表现出毒性症状。
