The effects of inabenfide (0. 05 to 2 g per nursery box) on rice plants were: one, the lengths of the second, third and fourth leaf sheaths significantly shortened; two, the foliage dry weight per cm of plant height, which is an indicator of good rice seedlings, increased; three, both angles of erectness of rice seedlings and a-naphthylamine oxidation increased; and four, the longitudinal length of epidermal cell of the fourth leaf sheath significantly shortened. Inabenfide was most effective

Full ripening, 1000-kernel weight and yield per hectare increased. The relation between the lodging degree and yield was investigated.
