水杨酸对切花菊保鲜效果和生理效应的影响
Influence of Salicylic Acid on Vase Life and Physiology of Cut Chrysanthemum
摘要
Abstract
Cut chrysanthemum cultivar Xiahuang were used in this experiment, the effects of salicylic acid (SA) on the vase life and physiological action of cut chrysanthemum were investigated. The results indicated that treatment B(20 g/L sucrose+200 mg/L 8-Hydroxyquinoline+200 mg/L citric acid+55 mg/L SA) was the best in retaining freshness, corolla diameter of cut chrysanthemum went up gradually and reached the maximum about the 10th day,and corolla diameter increased by 5. 234 cm comparing with initial diameter,the maximum fresh weight of flower stems increased by 29. 11％ ,and the vase life could be prolonged 14. 5 d and 9. 0 d respectively than the contrast (water) and treatment A(20 g/L sucrose +200 mg/L+ 8- Hydroxyquinoline+ 200 mg/L citric acid ). Comparing with the contrast, treatment B could mitigate water stress, the content of soluble protein increased by 2. 327-5. 831 mg/g, the content of chlorophyll in the leaf increased by 0. 278-0. 978 mg/g, and the free proline accumulation in the ray floret was reduced by 4. 333-17. 715 μg/g.关键词
