Confirmation of the Concentration of Salt-tolerance Screening for Famous and Precious Chrysanthemum[ Dendronthema × Grandiflora (Ramat.) ] Varieties
摘要
Abstract
[Objective] The aim was to confirm the best salt concentration of screening famous and precious chrysanthemum varieties, and provide a theoretical basis and technological support for screening the chrysanthemum varieties with salt-tolerance and introducing famous and precious chrysanthemum varieties in saline-alkali soil-area. [Method] 0.4, 0.6, 0.8 mol/L NaCl were used to treat famous and precious chrysanthemum varieties("Tanxiangshizi" , "Qiushuifurong" , "Qianxiuyinzhen" and "Caixia") respectively through soilless culture, and their salt injury indices were determined after treated 3, 6, 9, 12, 15, and 18 days. [ Result] When NaCl concentration was 0. 4, 0. 8 mol/L, the salt injury indices of 4 kinds of chrysanthemum varieties had a little significance in different determination time. Four chrysanthemum varieties plants appeared salt injury symptom when using 0. 8 mol/L NaCl to treat them a short time( within only 2 days) , so it could be used to quickly and rudely mass chrysanthemum varieties with salt-tolerance. While the plants did not appear salt injury symptom when using 0.8 mol/L NaCl to treat them a long time( after 18 days), so it was unsuitable to using as the concentration of salt-tolerance screening. When NaCl concentration was 0.6 mol/L, the salt injury indices of 4 kinds of chrysanthemum varieties had a big significance in different determination time. Thereinto, when treated 18 days, 1/2 plants of "Tanxiangshizi" and "Qiushuifurong" , all of "Caixia" plants, and part of "Qianxiuyinzhen" plants were dead; When treated 12 -18 days, the salt injury indices of 4 kinds of chrysanthemum varieties relatively stabilized in a certain range, which could be used as a basis for identifying the relative salt-tolerance of chrysanthemum varieties. [Conclusion] 0.6 mol/L NaCl is a valuable salt concentration in salt-tolerance screening of chrysanthemum varieties.关键词
