Abstract: With experiment cultivated in pots and contrived simulation of water adversity,method to determine soil moisture by electronic balance(made in Shanghai)and W.E.T Sensor(ML2x type,made in USA),the effect of water adversity on malondialdehyde(MDA,membrane lipid peroxidation product)content in leaves of different type super rice varieties from beginning to 30 d after panicle initiation was studied.The results showed that water treatment accelerated membrane lipid peroxidation and leaded to MDA content raise significantly,moreover,the influencing degree enhanced with growing process,lasting days of water controlled and leaf position fall.The MDA content in rice leaf was increased by water treatment,especially under-layer leaf,which obviously leaded to damage of enzyme and cell membrane,accordingly affected cell normal physiological metabolism.The MDA content and its increment of the 3rd leaf from top was higher,secondarily the 2nd leaf from top,and the effect flag leaf was relevantly lower.The effect of water adversity on MDA content in different rice varieties showed difference because of different sensitivity to stress,the influence of Shanyou 63 was greater,next,Ⅱyou 602,that of Liangyoupeijiu and Guodao 6 was less.

Key words: Super rice, Water adversity, Growth and development of panicle, M alondialdehyde( M DA)
