Analysis on Lithium Tolerance Characteristics of Lycium chinense Seeds under Different Salt Stress Conditions
The experiment selected Ningqi No.1,Ningqi No.5 and Ningqi No.7 as materials,the effects of NaCl solution at different concentrations on seed germination of Lycium chinense and the effects of LiCl solution at different concentrations on germination rate,germination potential,germination index,root length,shoot length and vitality index of three Lycium chinense varieties were studied.The results showed that with the increase of salt concentration,the root length and shoot length of Ningqi No.1 were inhibited.The root length and shoot length of Ningqi No.5 were firstly promoted and then inhibited.It inhibited the root length of Ningqi No.7,and promoted the shoot length first and then inhibited it.Low lithium concentration promoted germination rate,germination potential,germination index,root length,shoot length and vitality index of Ningqi No.1,Ningqi No.5 and Ningqi No.7,of which Ningqi No.1 had stronger lithium resistance than Ningqi No.5 and Ningqi No.7.
