茶多酚抑制红壤稻田脲酶及其对水稻生长的影响

试验了茶多酚抑制红壤稻田脲酶及其对其它几种酶、水稻根系活力和水稻生长的影响。试验表明茶多酚对红壤稻田脲酶具有较强的抑制作用 ,对红壤稻田蛋白酶、过氧化氢酶和纤维素酶抑制作用较弱。茶多酚对水稻根系活力和水稻生长也有较轻微抑制作用。茶多酚较氢醌的脲酶抑活作用强、副作用小 ,茶多酚是一种有较好前景的脲酶抑制剂。

TEA-POLYPHENOL INHIBITION TO UREASE OF PADDY SOIL DERIVED FROM RED SOIL AND ITS EFFECTS ON THE GROWTH OF RICE

The authose used tea-polyphenol as inhibitor and studied its effects on the urease and some other enzymes in paddy soil derived from red soil, as well as the vitality of rice roots and the growth of rice. The results show that its inhibition to urease of the paddy soil derived from red soil was fairly strong, whereas the inhibition to protein enzyme, catalase and cellulase in the soil was relatively weak. The tea-polyphenol also had a comparatively faint inhibition to the vitality of rice roots and the growth of rice. Compared with hydroquinone, the tea-polyphenol's side effects of inhibition was weaker, hence it is a better inhibitor.
