Effects of Water Deficit and Chitosan Spraying on Osmotic Adjustment and Soluble Protein of Cultivars Castor Bean (Ricinus communis L.)

摘要: The present study was aimed investigating the effect of water deficit and chitosan spraying on osmotic adjustment soluble protein cultivars castor bean under field condition. experiment carried out as a split factorial based randomized complete block design with three replications. results showed that caused increase significant (P<0.05) in concentration sugars proline content leaves bean. most amount total obtain Levels (D2: Water beginning flowering stage, D3: seedling 0.042%) minimum related to treatment control (D1: Irrigation , 0.014%) maximum (D3: stage) Irrigation). Also Deficit decrease Protein content. mean comparison shows Irrigation, 26.79%) from Flowering 21.04%). also had between different (P<0.01) sugars.
