摘要:
植物整个生长周期中苗期是最重要的生长阶段之一，这一时期将影响到植物后期的生长情况及采收品质。为探索适宜板蓝根种子播种的温度。通过室内人工气候培养箱模拟实际环境控制变量来培养板蓝根种苗，分别在10、15、20、25 ℃4个温度处理条件下进行，研究观察不同温度下板蓝根幼苗的发芽率、根长、株高等形态指标的情况。结果表明：在试验温度范围值内板蓝根幼苗发芽率、胚根长、株高、子叶长、子叶宽均随温度的升高而升高，呈正比例关系，且在25 ℃处理下各项指标达到最大值。表明在人工气候培养箱中不同温度处理条件下，试验温度范围值内板蓝根在幼苗期最适宜的生长温度在25 ℃左右。
Abstract:
The seedling period is one of the most important growth stages throughout the plant growth cycle.This period will affect the growth and harvest quality of the plant in the later period.In order to explore the suitable temperature for seed planting of radix isatidis.The seedling of radix isatidis was cultivated by simulating actual environment control variables in indoor artificial climate incubator.Under the conditions of 4 temperature treatments,10,15,20 and 25 ℃,the germination rate,root length and higher morphological index of the seedlings of radix isatidis were studied at different temperatures.The results showed that the germination rate,root length,plant height,cotyledon length and cotyledon width of the root of radix isatidis were increased with the increase of temperature,and the maximum value was reached at 25 ℃.It was shown that the optimum growth temperature of isatis indigotica at seedling stage is about 25 ℃ under different temperature treatment conditions in artificial climate incubator.
