摘要
为了促进形成一套剑麻抗斑马纹病的鉴定技术,本研究对剑麻斑马纹病最适宜接种条件进行了探讨,并利用活体叶片接种和离体叶片接种两种方式,以抗性不同的8个剑麻种质为试验材料,在人工气候箱和恒温室中进行剑麻抗斑马纹病接种试验,并与大田抗病性进行比较。结果表明:针刺法接种,25～30℃保湿培养是该病最适宜的发病条件;两种接种方法都能比较准确地鉴定剑麻种质对斑马纹病的抗病性,而活体叶片接种较离体叶片接种鉴定抗病性更加准确。
To promote a set of identification technology for agave resistance to zebra disease,the most appropriate inoculating conditions of agave zebra disease pathogen were explored,and in vivo inoculation in glasshouses and in vitro in artificial climate chambers were performed with 8 agave germplasms for checking disease resistance.The results were compared with those obtained from open fields.The results showed that needle penetration inoculation,25-30 ℃ and moisture retention were the most appropriate inoculating conditions.Both inoculating methods could identify the disease resistance and in vivo inoculation was more accurate.
