Effect of paclobutrazol on seed germination and seedling quality of rice

WANG Xiao-bo1,SONG Ting-ting2 1.College of Agronomy,Jilin Agricultural University,Changchun 130118,China; 2.Qingdao Xingpai Crop Science Co.Ltd.,Qingdao 266034,China)  
The effect of paclobutrazol on seed germination and seedling quality of rice(Oryza sativa L.) was studied.The seeds of Jinongda 808 were soaked in 400,500 and 600 times diluted paclobutrazol solutions.The results showed that the germination process can be accelerated by 500 times diluted paclobutrazol.The seed germination rate,germination index and leaf area were enhanced by 26%,4.8%~11.11% and 4.12% respectively,but plant height was decreased by 40%.Thus improved the accumulation of dry matter,increased root volume,and very favorable towards the cultivation of seedling.
