rice production system on the germination, seedling vigor of rice cv.
KDML 105 was evaluated through investigating the biochemical changes during
storage following seed coating techniques. The seeds were coated by traditional
fungicide (captan; CA), biological fungicide polymers [chitosan-lignosulphonate
polymer (CL) and eugenol incoporated into chitosan-lignosulphonate polymer
(E+CL)] and un-coated seeds as control (CO). CA significantly affected
the rice seed storability and the associated biochemical deterioration.
After 12 months storage, seed moisture content and seed water activity
increased that affected the germination rate and spread, seedling vigor;
seedling dry weight, shoot and root length, seedling growth rate and susceptible
to stress conditions. The loss of viability is associated with disturbances
of the cell membranes, the loss of enzymes; α-amylase, ascorbate
peroxidase APX and superoxide dismutase SOD activity, sugars and lipid
content accompanied by increased free fatty acid FFA and activated lipoxygenase
enzyme LOX. CL and E+CL performed the best of seed vigor, because they
could maintain the antioxidative scavenging enzymes are APX and SOD and
a high antioxidant activity. In addition, α-amylase activity and
sugar content increased which was positive correlated with seed germination
and vigor. These improvements were attributed to maintain the nutritive
reserve and dehydrogenase activity in seeds. Moreover, the biological
seed treatments stimulated the embryo growth and so speeding up the seedling
emergence.]]>Agrawal, A.A.,20028334083415Alexander, R.R., J.M. Griffiths and M.L. Willkinson,1985Asada, K.,200035514191431Zhao, F., S. Guo, H. Zhang and Y. Zhao,2006170216224Basra, S.M.A., M.N.
