- 摘要:
- 以中药材知母种子为试材，采用聚乙二醇（PEG）干旱胁迫和混合盐胁迫的方法，研究知母种子在胁迫条件下的发芽势、发芽率以及胚根与胚芽长等生长性状指标，以期为知母人工栽培提供科学依据。结果表明：随着PEG浓度和NaCl与NaHCO3（1∶1）混合溶液浓度的增加，知母种子萌发均受到抑制，种子发芽势、发芽率、胚芽与胚根长度与直径都与之呈显著的负相关。PEG不同浓度梯度胁迫下，知母种子发芽势由16%降至4%，发芽率由80%降至52%，且知母种子萌发的致死浓度为15%；NaCl与NaHCO3（1∶1）混合溶液胁迫下，知母种子发芽势由16%降至6%，发芽率由80%降至14%，且知母种子萌发的致死浓度为1.20%。知母种子有一定的耐干旱及耐盐胁迫能力。
- Abstract:
- Taking the seeds of Anemarrhena asphodeloides as materials,the germination potential,germination rate,radicle length and germ length of Anemarrhena asphodeloides seeds were studied under PEG stress and mixed salt stress,in order to provide scientific basis for artificial cultivation of A.asphodeloides.The results showed that as the increasing of the concentrations of PEG and salt,the seed germination of A.asphodeloides was inhibited,the germination potential,the germination rate，length and diameter of radicle and germ showed a significant negative correlation with it. Under the PEG stress,A.asphodeloides seed germination potential decreased from 16% to 4%,the germination rate decreased from 80% to 52%,and the lethal concentration of the seed germination was 15%. Under the stress of NaCl and NaHCO3 (1∶1) mixed solution,the A. asphodeloides seed germination potential decreased from 16% to 6%,the germination rate decreased from 80% to 14%,and the A. asphodeloides seed germination lethal concentration was 1.20%.The results showed that the A. asphodeloides seed has certain resistance to drought and salt stress.
