密度和激素对香樟家系幼苗生长及株型的影响研究
Effects of Planting Density and Hormones on the Growth and Plant Architecture of Camphor Tree(Cinnamomum camphora)Families
摘要
Abstract
In order to explore the effects of planting density and exogenous hormones on early growth and plant architecture of Cinnamomum camphora family seedlings,this study used two-year-old seedlings from different families as experimental material.The effects of va-rious planting densities and the application of different types and concentrations of exogenous hormones on the growth and plant architecture of C.camphora trees seedlings were ana-lyzed.The results showed that the growth and architecture of C.camphora seedlings signif-icantly varied among families with different architectures.Among them,the'Fen 1'family exhibited superior individual growth performance,while the'Zhi 2'family demonstrated op-timal plant architechture.A planting density of 5 cm×5 cm promoted increased branch height and trunk straightness of C.camphora seedlings to some extent but limited overall growth,whereas a density of 20 cm×25 cm provided a more balanced performance in both growth and plant architecture of C.camphora seedlings.The application of exogenous hormones had nota-ble effects on seedling plant architecture,with the combination of NAA+6-BA particularly pro-moting desirable architectural traits.These findings provide technical support for the early control of plant architecture in timber-oriented C.camphora seedlings,and also lay a foun-dation for further studies on the regulatory mechanisms of C.camphora.关键词
