Effect of Illumination Intensity on The Yield and Agronomic Traits of Gentiana scabra Bge
摘要
Abstract
This study evaluated the effects of different illumination intensity on The Yield and Agronomic Traits of Gentianascabra Bge.under three natural illumination conditions of 25%,50% and 100%(bare land cultivation). The result showed that different illumination intensity have no significantly affected on aerial part traits of Gentiana scabra Bge.The highest value of leaf length were found in 50% natural illumination treatment,which were signifi-cantly higher than 100% and 25% natural illumination treatments.The highest value of stem diameter were found in 100% and 50% natural illumination treatments,which were significantly higher than 25% natural illumination treat-ment.Different treatments of root characters have different effects on root length,single root weight,root thick-ness and the number of fibrous root.The highest value of root length and single root weight were found in 100%and 50% natural illumination treatments,which were significantly higher than 25% natural illumination treatment. There were no significant difference between the treatments of root thickness and the number of fibrous root.The highest value of plot yield were found in 50% natural illumination treatments,which were significantly higher than 100% and 50% natural illumination treatments.Comprehensive analysis of agronomic traits,the optimum natural illumination treatment was 50%,which could promote the plant growth of Gentiana scabra Bge.and increase the yield.关键词
