繁殖方式对杉木根系不同序级生物量、形态性状及碳氮含量的影响
Effects of propagation methods on biomass,morphological traits and carbon and nitrogen contents of different orders of Chinese fir roots
[目的]了解繁殖方式对杉木幼苗根系不同序级生物量分配及生长的影响,有利于认识杉木因繁殖方式影响幼苗个体根系早期发育水平及生长策略的差异。[方法]以种子萌发、组织培养和无性扦插等繁殖方式培育 1年的杉木幼苗为研究对象,测定比较杉木根系不同序级生物量、形态性状与组织碳氮含量的差异,并分析根系生物量不同序级测定指标之间的内在关系,探究杉木幼苗因繁殖方式影响根系早期生长策略的差异性。[结果](1)不同繁殖方式培育的杉木幼苗根冠比差异达显著水平(P＜0.0…查看全部>>
[Objective]Understanding the effects of propagation methods on the biomass allocation and growth of different order roots of Chinese fir saplings is helpful to understand the differences in the early development level and growth strategies of individual roots of Chinese fir saplings due to propagation methods.[Method]Chinese fir saplings cultivated for 1 year by seed germination,tissue culture and rooted cutting were used as the research objects to determine…查看全部>>
