Abstract:

The aim of this research was to study the effects and mechanism of paclobutrazol (PP333) treatments on rapeseed yield and mechanical harvesting. PP333 was foliage sprayed with different concentrations at two stages (the closing of crop and the start of flower bud), on two varieties of rapeseed Yangguang 2009 and Fengyou 520. Our results demonstrated that PP333 treatment significantly increased the rapeseed lodging resistance, silique shattering resistance and yield. PP333 of 300 mg L–1 at the bud beginning more significantly enhanced lodging resistance and silique shattering resistance, whereas 150 mg L–1 PP333 at crop closing period more significantly increased yield of the two varieties. PP333 treatment reduced seed number per pod, while enhanced pods per plant, 1000-grain weight and yield. At the same time, PP333 treatment increased root crown diameter, root-top ratio (fresh) and snapping resistance, whereas it reduced plant height and culm lodging index, resulting in reduced angle of plant lodging, which indicates an improvement in the resistance of root and stem lodging. Silique shattering resistance was increased due to increased silique water content, silique dry weight and delayed pod maturity. In summary, the crop closing period and 150 mg L–1 PP333 are the best treatment time and concentration for significantly enhancing the abilities of lodging resistance, silique shattering resistance and yield, which could meet rapeseed mechanized production.
