欧美杨幼苗对不同光照时长的响应
Growth of Populus×euramericana Plantlet under Different Light Durations
[目的]为了明确不同光照时长在杨树早期育苗过程中对其幼苗生长的影响。[方法]本文以16个欧美杨无性系幼苗为研究对象,利用全光谱LED灯设计11 h、12 h、13 h、14 h、15 h和自然光(CK)六个光照处理。进行了150 d的光照处理实验,每隔15 d对幼苗的苗高(H),地径(GD),节数(NN),叶片数(NL)和叶片相对叶绿素含量(SPAD值)进行调查和测量。通过建立并筛选生长模型的方式展示欧美杨幼苗对不同光照时长的响应,同时对其生长节…查看全部>>
[Objective]The aim of this study was to investigate the effect of different light duration on the growth of Populus plantlets during the early seedling raising process.[Method]In this paper,16 seedlings of Populus×euramericana clones were taken as research objects,using full-spectrum LED lights,six light treatments of 11 h,12 h,13 h,14 h,15 h,and CK(greenhouse natural light)were designed to examine the response of Populus×euramericana plantlets to light dura…查看全部>>
