Effects of mixtalol and paclobutrazol on photosynthesis and yield of rape ( Brassica napus )

摘要: Photosynthetic and yield effects of paclobutrazol mixtalol sprayed, respectively, on rape at the three-leaf stage shoot or anthesis stages were examined. They significantly increased chlorophyll content photosynthetic rates, prolonged leaf longevity, green pod area. Paclobutrazol-treated plants shorter, more branched, produced seeds. Foliar sprays podding percentage, pods per plant, seeds pod. A high seed 1809.0 kg/ha was obtained with sprayed anthesis, while significant yields also achieved treatments stage. The reduced when both growth regulators applied together, this led to reductions. No adverse from observed oil content, erucic acid, glucosinolate content. total production by 20.9%, 14.4%, 13.4%, over controls.
