Study on Seed Germination Characteristics and Salt Tolerance of Hyssopus cuspidatus Boriss.
摘要
Abstract
To explore the suitable germination conditions for Hyssopus cuspidatus Boriss.,seeds were used as materials to study their germination characteristics under different temperatures(15,20,25,30,35℃),hormone solutions(100 mmol/L IAA,6-BA,GA₃),and salt solutions(NaCl,Na₂CO₃)at various concentrations.Parameters including germination rate,germi-nation potential,seedling plumule length,radicle length,fresh weight,and dry weight were measured.Regression analysis was employed to determine the seed tolerance to salt stress.The results showed that the optimal temperature for seed germi-nation of H.cuspidatus was 20℃.Soaking seeds with exogenous hormones GA₃ and 6-BA improved the germination rate,germination index,and vigor index,exhibiting a positive promoting effect on seed germination.With increasing salt concen-tration,all germination indices of NaCl soaked seeds showed promotion at low concentrations but inhibition at high concentra-tions.For Na₂CO₃ soaked seeds,all indices showed a gradual decreasing trend.The seeds of H.cuspidatus exhibited higher tolerance to NaCl,with a lethal concentration of 212.48 mmol/L.These findings provided a reference for seedling propagation and selection of standardized planting bases for Hyssopus cuspidatus Boriss.关键词
