包膜柠檬酸处理对雪里蕻根系活力的提高作用最为显著，包膜柠檬酸和磷肥在提高产量的同时也显著降低植株对重金属的吸收。

A new procedure for virus concentration from water samples has been developed. This method called calcium flocculation-citrate buffer method involves virus flocculation formed by 1 mol/L Ca2+ solution and its flocculating agent, virus release with sodium citrate dissolution (0.3 mol/L, pH5.0), and virus reconcentration by ultrafiltration.

研究建立了一种从水体中浓缩病毒的新方法，即钙离子絮凝-柠檬酸缓冲液洗溶法，该方法的要点是先用一定量的钙离子溶液和钙离子絮凝剂絮凝水体中的病毒，再用pH 5.0的0.3 mol/L的柠檬酸缓冲液洗溶，然后再进一步超滤浓缩。

Under different stresses, we tested the expression of citrate synthase gene in rapeseed leaf by using semi-quantitative PCR. The expression of citrate synthase gene had no obvious change in stresses of salt, dark, high illumination, while was increased at different time in treatments of water logging, drought, IAA, and 6-BA. Interestingly the effect of ABA was contrary to that of IAA. In the treatment of sclerotium blight, the expression of citrate synthase gene was depressed. There was a saddle curve of citrate synthase gene expression in the treatment of gibberellin.

对油菜幼苗进行植物生长调节物质、高温和低温、强光照和弱光照、盐、菌核病、干旱和水渍等处理，采用半定量PCR法对油菜叶片柠檬酸合酶基因的表达模式进行检测，发现在盐胁迫、暗光和强光的处理下，柠檬酸合酶基因的表达基本没有变化；在水渍、干旱、IAA和6-BA胁迫下，其表达有所升高，但出现峰值的时间不同，ABA对表达模式的影响与IAA相反，感染菌核病后其表达降低；对GA3的应答呈鞍型。
