外源乙烯及氯化钴对磷胁迫下杉木幼苗根系生长的影响
Effects of exogenous Ethylene and Cobalt chloride on root growth of Chinese fir seedling under low phosphorus stress
本文通过研究不同浓度乙烯利对低磷环境下杉木幼苗根系形态以及生理指标的影响,为揭示杉木幼苗适应养分胁迫环境内在机制提供参考依据。采用沙培法,分别在供磷和不供磷环境下添加不同浓度的乙烯利(0g/kg、0.01g/kg、0.1g/kg、02g/kg、0.4g/kg)氯化钴浓度为(0g/kg、0.01g/kg、0.05g/kg、0.1g/kg、0.2g/kg)进行试验。结果表明:1)不同添加剂对杉木幼苗的根长、根表面积和根体积之间达到显著差异(p<…查看全部>>
By studying the effects of different concentrations of ethephon on the root morphology and physiological effects of Chinese fir seedlings under a low-phosphorus environment,it provides a reference for revealing the internal mechanism of Chinese fir seedlings adapting to a nutrient-stress environment.The different concentrations of ethephon(0 g/kg,0.01 g/kg,0.1g/kg,0.2g/kg,0.4 g/kg)and Cobalt chloride(0 g/kg,0.01 g/kg,0.05 g/kg,0.1 g/kg,0.2 g/kg)were used und…查看全部>>
