不同LED光质对丝瓜枯萎病菌及枯萎病发生的影响
Effects of Light Quality on Fusarium Oxysporum and Fusarium Wilt Disease of Loofah (Luffa Acutangula)
摘要
Abstract
To explore the mechanism of light quality regulation on disease,effects of 11 kinds of light quality (range from 340 ～ 450 nm) on Fusarium oxysporum (Schl.) f.sp.luffae and Fusarium wilt were tested.Compared with the treatment of white light,mycelia growth of F.oxysporum was inhibited in treatments of 370 nm and 400 nm,while mycelia growth was slightly promoted in treatment of 340 nm,395 nm,410 nm,440 nm and 450 nm.Sporulation of F.oxysporum was promoted in all light treatments,and that was the highest under 370 nm light treatment.There were significant effects of promoting spore germination in treatments of 375 nm,425 nm and 440 nm,while certain inhibitory effect was found in 395 nm treatment.After the light pretreatment of 72 h,the development of wilt disease slowed in treatments of 370 nm,380 nm and 425 nm,however,certain role in promoting the development of disease was found in treatments of 375 nm,440 nm and 450 nm.关键词
