摘　　要：为探究不同光质对西瓜和甜瓜幼苗质量的影响,本试验以西瓜品种甜王50和甜瓜品种青秀2号为试材,于光照培养箱中进行育苗,以白光为对照(CK),分析4种不同比例的组合光R4B1、R6B1、R4B1G1、R6B1G1处理对幼苗生长的影响。结果表明,与CK相比,组合光均促进了西瓜和甜瓜幼苗的生长,红蓝光显著促进了西瓜幼苗的生长,红蓝绿光显著促进了甜瓜幼苗的生长,西瓜和甜瓜幼苗生长的最佳光质组合分别是R6B1和R4B1G1。R6B1和R4B1G1处理可有效提高幼苗的株高、茎粗、叶面积、根系生长、物质积累等形态指标和叶片光合色素含量、可溶性糖含量、根系活力等生理生化指标,有助于幼苗进行物质积累,进而达到壮苗的效果。In order to explore the effects of different light quality on watermelon and muskmelon seedling quality,this experiment took watermelon variety‘Tianwang 50’and muskmelon variety‘Qingxiu No.2’as test materials,grew them in light incubator and taking white light as the contrast(CK).Then,the experiment analyzed the effects of combination light of R4B1,R6B1,R4B1G1 and R6B1G1 with 4 different ratio treatments on seedling growth.The results showed that comparing with the CK,combination light had promoted the growth of watermelon and muskmelon seedlings,red and blue light significantly accelerated the growth of watermelon seedlings,and red,blue and green light significantly enhanced the growth of muskmelon seedlings.The best light quality combinations for watermelon and muskmelon seedlings were R6B1 and R4B1G1,respectively.R6B1 and R4B1G1 treatments could effectively improve the morphological indexes,including plant height,stem diameter,leaf area,root system growth and matter accumulation,and physiological and biochemical indexes such as leaf photosynthetic pigment content,soluble sugar content and root system activity,etc.Those were all helpful to substance accumulation of seedlings and then achieving the effect of strong seedlings.
