Abstract
Growth and yield responses to plant density (6.75 × 10 4 , 9.75 × 10 4 and 12.75 × 10 4 plants ha –1 ) and stage of transplanting (30, 35 and 40 days after sowing) of winter oilseed rape cultivar HO 605 were investigated in two field trials in the 1996/97 and 1997/98 growing seasons at Zhejiang University Farm, Huajiachi Campus, China. Results revealed a progressive decrease in leaf area per plant in response to increasing plant density and delayed transplanting, though leaf area m –2 and leaf area index were higher in high‐density plants. Number of effective branches and pod per branch decreased with increasing plant density and delayed transplanting. There were no significant differences in the mean seed weight among treatments. Although the average number of seeds per pod was significantly lower for high‐density plants and delayed transplanting, the economically highest seed yields were realized in relatively high‐density plants. Seed oil content was negatively affected by increasing plant density, but no significant differences were observed with delayed transplanting. The highest seed yields of 1730.7 and 1748.1 kg ha –1 with no significant differences were observed for plant densities of 9.75 × 10 4 and 12.75 × 10 4 plants ha –1 , respectively, transplanted at 35 and 30 days after sowing.
