摘  要:
以"农大牛角椒"为试材,以双色和三色光源为处理,研究不同配比红蓝光源对辣椒幼苗形态建成及生理特性的影响,以期为LED光源在园艺栽培中的应用提供参考。结果表明:红蓝黄光比5∶4∶1处理辣椒幼苗的株高、根长、侧根数、叶数、干鲜质量均最大,分别为6.00cm、6.01cm、12.75条、5.17片、0.458g、0.069g,茎粗以红蓝黄光比5∶3∶2处理最大,为1.32mm。所有处理对辣椒幼苗的可溶性蛋白质含量均有促进作用。红蓝紫光比5∶3∶2处理的辣椒幼苗CAT、POD活性最高,分别为55.40 mmol·min-1·g-1和302.46U·min-1·g-1;红蓝绿光比5∶4∶1处理的可溶性糖含量最高,为0.028%;红蓝黄光比5∶3∶2处理对辣椒幼苗根活力影响最大,为0.203mg·g-1·h-1;所有处理均有利于形成辣椒幼苗叶绿素a、叶绿素b及叶绿素总量。从隶属函数法综合评价来看,红蓝黄光比5∶4∶1位列第一,可作为促进辣椒幼苗生长的最优光源组合。

摘  要:
Hot pepper was taken as materials and double color and three color light sources as processing,the effects of different blue and red ratio of light quality combination on morphogenesis and physiological characteristics of hot pepper seedling were studied,in order to provided the reference for application of LED light source in horticulture planting.The results showed that the plant height and fresh weight and dry weight and root length and lateral root number and leaf number of RBY 5∶4∶1 light quality treats were all the highest,which were 6.00 cm,6.01 cm,12.75 roots,5.17,0.458 g,0.069 g,respectively.The stem diameter of RBY 5∶3∶2 light quality treat was the highest,that was1.32 mm.All treats were beneficial of improving the content of soluble protein of hot pepper seedling.The activities of CAT and POD of RBP 5∶3∶2 light quality treat were the highest,which were55.40 mmol·min-1·g-1 and 302.46 U·min-1·g-1.The content of soluble sugar of RBG 5∶4∶1 light quality treats was the highest,which was 0.028%.The Root activity of RBY 5∶3∶2 light quality treat was the highest,which was 0.203 mg·g-1·h-1.All treatments were beneficial of improving the content of chlorophyll a and chlorophyll b and chlorophyll.Comprehensive evaluation,RBY 5∶4∶1 could be looked as the best light for improving the growth of hot pepper seedling.
