Effects of Exogenous Calcium and Calcium Ion Inhibitor on Cold Resistance of Pistil of Kernel Apricot

With a kernel apricot cultivar Youzhu 07-3 as the test material, the effects of exogenous calcium and calcium inhibitor on the cold resistance of pistils were investigated. In the bud germination and enlargement period, exogenous calcium and calcium ion inhibitor were sprayed to the kernel apdcot trees, respectively. At the full-bloom stage, a certain number of flower branches of kernel apricot were sam- pied and subjected to low-temperature stress indoor, and the soluble sugar content, MDA content, SOD activity and POD activity in the pistils were determined. The results showed that exogenous calcium increased the soluble sugar content, reduced the MDA content and improved the SOD and POD activity in pistils, and it significantly relieved the cold damage to pistils and improved the cold resistance of pistils; while exogenous calcium ion inhibitor showed the opposite effects.

黄巢诗与联句的语言密码

传说黄巢所作的《题菊花》诗及其联句,最早记载于南宋后期的文献《贵耳集》中,这也是宋朝唯一的记载。此诗和联句的语言,留下了太多宋朝习用语的痕迹。'蕊寒''香冷''一处开''总首''赭黄衣'等词和短语,大都是宋朝诗人惯用的意象语言。在唐朝及先唐文献中,'蕊寒''总首'以及'一处开'等词语搭配,全无用例;'香冷'指向花,只有一例,且非菊花;'赭黄衣'也仅有一例,出现于不易流传的僻见书籍中。一个五岁的儿童,能首创出如此多的艺术语言,这在古代有记载的早慧儿童之中,绝无仅有。语言密码的破译,诸多的关联得出一个结论:它们不可能是唐人黄巢之作。

心倾谦德

心倾谦德寄年华,起步河庄尤可嘉。劲筑高坛舞清影,惊开宝地育新芽。汗浇文脉情无尽,鹏举诗囊乐未涯。莫道今秋寒蕊瘦,春来满苑怒生花。
