Effects of Diethyl Aminoethyl Hexanoate Seed Soaking on Germination Characteristics of Psathyrostachys juncea
摘要
Abstract
To further improve the seed germination ability of Psathyrostachys perennis Keng(syn.P.perennis Keng),seeds of the cultivar'Moqinwula'were used to investigate the effects of exogenous plant growth regulator diethyl aminoethyl hexanoate(DA-6)on seed germination characteristics.The results showed that both DA-6 concentration and soaking dura-tion had significant effects on seed germination,exhibiting a typical low-promotion and high-inhibition effect.Among all treatments,soaking seeds in 100 mg/L DA-6 for 14 hours was identified as the optimal combination.Under this condition,the seed germination percentage,germination energy,and germination index reached 76.00%,50.00%,and 80.86,respec-tively,which were significantly higher than those of the control group by 40.74%,114.32%,and 52.36%,respectively.In conclusion,soaking seeds of P.perennis Keng in 100 mg/L DA-6 solution for 14 hours prior to sowing was an effective pretreatment method to break seed dormancy and improve seedling establishment quality.This approach provides a valu-able reference for ecological restoration using native grass species and successful establishment of cultivated grasslands.关键词
