Abstract
Treatments with methylglyoxal bis (guanylhydrazone)(MGBG) apparently decreased pollen fertility and bagged seed settings of Nongken 58S short day fertile rice plants, without affecting its normal growth. 10 -4 mol·L -1 MGBG was the optimum concentration for short day fertile rice plants, whereas MGBG in different concentrations did not function very well when spraying on long day sterile rice plants. The treatment mainly reduced the seed settings of the middle and bottom branches in short days and had little effect on those of the top branches. MGBG treatment resulted in an increase of putrescine content and a reduction of spermidine and spermine; the latter of which could be inferred as one of the causes of sterility.
