印度芥菜（Brassica juncea（L.）Czern＆Coss.）容易受到多种病害的为害,如黑斑病、白锈病、霜霉病和白粉病。抗性的生化基础研究清楚地表明酚类物质的含量对于提高植物的抗性水平很重要。因此,本研究采用了来自不同遗传背景的印度芥菜亲本的3个杂交组合为材料,研究了酚类物质含量的基因型效应。研究采用了RH8113×RC781（R×R）、UDN69×RH9624（R×S）和Varuna×Sarita（S×S）3个杂交组合的6个世代材料（P1、P2、F1、F2、B1和B2）。分别在正常（E1:10月21日）和迟播（E2:11月23日）两种环境条件下,对不同世代杂交后代进行了评价,紧密家系区组设计（compact family block design）,3次重复,试验在希萨尔的CCS哈里亚纳农业大学植物育种系的研究地内进行。不管亲本是否抗白锈病,播种后35天和播种后65天的植株中酚类物质的含量,均以E1环境下高于E2环境下。抗病品种酚类物质的含量高于感病品种。感病后,感病品种与抗病品种相比,酚类物质含量表现出了大幅度的下降,说明感病后能否保持高水平的酚类物质含量对于产生抗白锈病性更为重要。在本研究中的大部分杂交组合中,酚类物质的含量受到加性效应及非加性效应以及上位性效应的控制。根据本研究的结果,我们主张在分离群体中进行群内杂交,将有助于负责控制酚类物质含量的等位基因的累积。上位性效应的存在说明,为了提高酚类物质的含量,应当在高分离世代中进行目标性状的选择。

1998年进行旱地秋植甘蔗的田间试验，研究了15个早熟、中迟熟甘蔗品种的生理特性，结果表明，中迟熟甘蔗品种B0128的甘蔗产量超过其它品种，收获时蔗汁的蔗糖分最高，而且九月份的叶面积指数，叶片叶绿素a、b含量和脯氨酸含量也最高。六、九月份的叶面积指数，一月中旬的叶绿素a、b含量和蔗汁蔗糖分都与甘蔗产量极显著正相关。脯氨酸含量与甘蔗产量之间也有正的关系。因此，在选育耐旱甘蔗品种时就应该考虑这些生理特性。

The CDEX-10 experiment searches for light weakly interacting massive particles, a form of dark matter, at the China Jinping Underground Laboratory, where approximately 10 kg of germanium detectors are arranged in an array and immersed in liquid nitrogen. Herein, we report on the experimental apparatus, detector characterization, and spectrum analysis of one prototype detector. Owing to the higher rise-time resolution of the CDEX-10 prototype detector as compared with CDEX-1 B, we identified the origin of an observed category of extremely fast events. For data analysis of the CDEX-10 prototype detector, we introduced and applied an improved bulk/surface event discrimination method. The results of the new method were compared to those of the CDEX-1 B spectrum. Both sets of results showed good consistency in the 0-12 ke Vee energy range, except for the 8.0 keV K-shell X-ray peak from the external copper.
