抗蚜虫转基因枸杞株系的光合生理特征 总被引:4,自引:0,他引:4
对5个转基因枸杞株系的光合生理进行测定,结果表明:有1个株系的叶片叶绿素(CHI)含量显著低于对照,叶绿素荧光参数和光合气体交换参数也显著低于对照,其它4个株系与对照相比变化不大。说明转基因对枸杞植株的光合生理影响不大。 相似文献

壳聚糖涂膜对枸杞鲜果常温保鲜的研究(英文) 总被引:1,自引:0,他引:1
[Objective] The aim was to study the preservation of fresh Chinese wolfberry fruit via chitosan coating. [Method] Using Chinese wolfberry "Ningqi No. 1" as experimental material, the fresh fruits were coated by different concentrations of chitosan(0.75%, 1.00%, 1.25%, 1.50% and 1.75%) at room temperature to study the changes in weight loss rate, rate of rotten fruits rot, soluble solid content and vitamin C(Vc) content. [Result] Of all the treatments, the fruits coated with 1.25% chitosan showed lowest rate of rotten fruit and weight loss rate, and highest Vc and soluble solid content, presenting the optimal fresh-keeping effect. [Conclusion] Chitosan coating is helpful for the preservation of fresh Chinese wolfberry fruit at room temperature. 相似文献
