The mycelial growth of Rhizoctonia solani was promoted by vanillic acid and syringic acid at levels of 0.1~1 mM/L, and it was inhibited remarkably by p-counaric acid of over 1mM/L and modestly by ferulic acid. The radial extent of mycelia of Fusarium solani was increased significantly by ferulic acid of 0.1~1 mM/L and limitedly by p-coumaric acid. vanillic acid had paradoxcial effects on the growth, positively at low levels and negtively at high levels, on which Syringic acid had a slight effect.

试验结果显示：浓度为0.1~1mM/L的丁香酸对西洋参立枯丝核菌菌丝生长具有促进作用，香草酸也有一定的促进作用，但不呈浓度效应，浓度在1mM/L以上的香豆酸对其有显著的抑制作用，阿魏酸也有一定抑制作用；对于西洋参根腐菌，阿魏酸对其生长有明显促进作用，香豆酸也有一定促进作用，香草酸表现为低浓度促进，高浓度抑制作用，0.1~1mM/L丁香酸对其生长基本无影响。

Through the SEM observation, we discover the single lotus fiber is composed of several tiny fibers with diameter approximately 4μm, and has horizontal burls in the lengthwise direction. spacing 3~5μm.

经SEM观测，发现莲纤维是由数根直径约4μm的单丝横向缔合而成，纵向有横节，间距3μm～5μm。

This experiment selecetd apex , flower bud and radicle of Camellia sinensis cv. Longjing 43 as research objects picked from the tea garden of Anhui Agricultural University. In this experiment ,three kinds of Chromosomal techniques were used ,including conventional sheeting method , disassociating cell wall hypoosmotic method and macrocoils method.

本试验以安徽农业大学茶园中龙井 43 的芽尖、花蕾以及其茶籽培养的幼根为研究对象，采用传统的压片法、去壁低渗法、风油精法三种制片方法，进行系统的比较和分析，这三种方法均能找到茶树体细胞有丝分裂相。
