The 11 Chinese and 10 Japanese silkworm varieties were feed with NPV,and the disease incidence was investigated.The result showed that the highest disease incidence in Chinese silkworm varieties was 27,the average incidence was 45.56%,and of which the lowest was E-chun,the average incidence was 34.86%.The highest disease incidence in Japanese silkworm varieties was 812,the average incidence was 48.84%,and of which the lowest was 9902,the average incidence was 32.62%.SPSS analysis indicated that there was no significant difference between the Chinese silkworm varieties,and there were significant differences between the Japanese silkworm varieties.9902 had the strong resistance to NPV,and 812 had low resistance to NPV.

[目的]研究桑枝提取物对红色毛癣菌的抑制活性，揭示其抑菌功效的物质基础，为利用桑枝开发治疗足癣的生物制剂提供理论参考依据，也为临床治疗真菌感染提供实验依据。
植物钠氢反转运蛋白(NHX)在植物钠钾离子平衡、细胞pH 调节中起着重要的作用.桑树是一种传统的经济树种，其桑叶是家蚕的主要饲料来源，然而它也可以适应多种不同的极端环境，如高盐环境.然而，目前对桑树NHX 基因的功能还知之甚少.本研究，我们克隆和鉴定到了7 个桑树NHX 基因，通过对其进化和基因结构分析表明，桑树NHX 基因家族主要分为3个亚家族.对其表达模式分析发现MaNHX 基因在策沙和粤桑这
[目的]探讨桑枝提取物及其6 种多酚单体化合物(氧化白藜芦醇,白藜芦醇,桑皮苷A,芦丁,槲皮素和桑色素)保护DNA 免受紫外线损伤的能力,并评估这六种常见多酚单体化合物在桑枝提取物保护DNA 活性中的贡献度,为桑枝开发利用奠定理论基础。[方法]利用75％的乙醇为提取溶剂,超声波辅助提取桑枝粉末,滤液低温低压浓缩；将桑枝提取物及所含的六个单体化合物与质粒DNA混合均匀,于紫外线下照射30min,再利
植物三聚体G 蛋白由α、β 和γ 三个不同亚基组成，在植物响应和抵抗非生物胁迫中具有重要的作用.然而，植物G 蛋白在干旱胁迫下的作用机制并不完全清楚，特别是β 亚基的功能还存在争议.本研究，我们发现拟南芥(Arabidopsis thaliana L.)G 蛋白β 亚基的突变体agb1-2-1 和agb1-3-2 对干旱的敏感性要强于野生型植株.将桑树(Morusalba L.)G 蛋白β 亚基编
激光诱导击穿光谱(Laser-induced Breakdown Spectroscopy)简称LIBS,是一种基于原子发射谱线的物质成分元素分析技术。相比与传统分析方法,其具有所需样品少、样本制备简单、样本损伤小、分析检测迅速、多元素同时检测等优点,目前已经广泛应用于固态、液态、气态等各类物质成分元素分析中,它也被视为未来进行快速分析检测的一种新型技术。
