摘要:
灰霉病是百合的主要病害之一，严重影响百合生产，筛选高抗种质资源是百合抗病育种的重要途径之一。本研究对不同百合种质资源叶片进行离体接种，结合扫描电镜观察，并进行活性氧、相关酶活性的测定。结果表明，卷丹百合属于高感（HS）种质，岷江百合-1、岷江百合-2、杂交种2065-1属于中抗（R）种质，宜昌百合、湖北百合、Champion Diamonds、雷林石、Craming Diamonds、红唇、杂交种2065-22属于高抗（HR）种质。接种灰霉菌后，高抗种质湖北百合叶片中过氧化氢含量变化更为剧烈，同时超氧阴离子含量会出现2次峰值，而高感种质卷丹百合则只有1次峰值。接种灰霉菌后，百合叶片中超氧化物歧化酶（SOD）活性与百合抗病性具有相关性。
Abstract:
Grey mold is one of the main diseases of lily, which seriously affects lily production. Thus, screening of high resistant lily germplasm is an important aspect of lily disease-resistant breeding. In this study, the leaves of different lily germplasm resources were inoculated in vitro, leaf structure and conidia growth condition were observed through scanning electron microscopy, and reactive oxygen species (ROS) and the related enzyme activities were determined. The results indicated that Lilium lancifolium belonged to the high-sensitivity (HS) germplasm. Lilium regale-1, Lilium regale-2 and the hybrid 2065-1 belonged to the middle resistance (R) germplasms. Lilium leucanthum, Lilium henryi, Champion Diamonds, Lellin Stone, Craming Diamonds, Red Lips, hybrid 2065-22 belonged to high resistance (HR) germplasms. After inoculation with Botrytis cinerea, the content of H2O2 in leaves of high resistant germplasm Lilium henryi changed dramatically, and the content of superoxide anion showed two peaks, while only one peak was found in Lilium lancifolium. After inoculation with Botrytis cinerea, the activity of superoxide dismutase (SOD) in lily leaves was correlated with the disease resistance.
