Effect of Soda Saline-sodic Stress on the Panicle Traits and Yield Components of Rice Variety Changbai 9

doi:10.7668/hbnxb.2010.S2.014

Abstract

Abstract: "Studied on panicle traits and yield components of rice variety Changbai9 in pot following soda saline-sodic stress.The results showed that with soda saline-sodic stress increased amount of secondary branches,grains of secondary branches,ripened grains of secondary branches were significantly decreased.Amount of secondary branches on panicle was considered as the most important effecting factor for single panicle yield.Yield of Changbai9 were significantly reduced due to total amount of spike decreased under saline-sodic stress.Therefore,water and fertilizer regulation was more important to increase number of florets on panicle and decrease degradation of secondary branches at Changbai9 booting stage under saline-sodic environments."

Key words: Rice, Salinity and sodicity, Panicle traits, Yield
