Effects of gibberellin acid(GA)and paclobutrazol(PP333) utilization on growth and fatty acids of safflower
摘要
Abstract
To regulate safflower growth and seeds quality,hormone effects were investigated by using GA(30, 100,170mg/L)and its biosynthesis inhibitor PP333(30,90,150mg/L). Hormones were sprayed at elongation stage. Several agronomic traits were measured and fatty acid in vegetative organs and seeds were analyzed by gas chromatography/mass spectrometry( GC-MS). Results showed that GA increased plant height and branch length significantly,and decreased primary branches and total capitulums per plant. Initial flowering date was delayed for 1-4 days. GA spray significantly increased flower linoleic and linolenic acid contents. GA(30mg/L)increased seed linoleic acid to 67 . 83%,which was significantly higher than that of water control( 62 . 58%). PP333 signifi-cantly decreased branch length,delayed the initial flowering date for 1-2 days with little effects on other traits. PP333(150mg/L)increased seed oleic acid to 20. 05%,which was significantly higher than that of control (15. 24%). It also remarkably increased the seed O/L at 20d after flowering. These results indicated that 30mg/L GA could be used to improve seed linoleic acid,and 150mg/L PP333 to improve oleic acid.关键词
