Abstract: Young leaves of Kabuli chickpea as well as soybean Xiangdou No.3, which are the current plants that studied in our laboratory were selected as materials. Effects on protoplasts yield and survival rate of different enzyme combination, concentration of D-Mannitol in enzyme combinations, pH of enzyme combinations and enzymolysis time are detected. The results showed that, the best condition for Xiangdou No.3 leaf protoplasts isolation is to rotate the cut materials for 6 hours in enyzme solution under temperature of 27 ℃ and rotate speed of 45 r/min for 6 h. Onozuka R-10 (0.5%), Hemicellulase (0.8%), Macerozyme R-10 (0.8%) in combination with Pectolyase Y-23 (0.4%) dissolving in CPW solution with MES (0.1%) and Mannitol (10%), pH 6.0 was found best for protoplasts isolation of Xiangdou No.3 leaves.The best condition for protoplasts isolation of Kabuli chickpea is to put the cut materials into enzymatic hydrolysate enzymolyse for 7 to 8 hours under temperature of 27 ℃ and rotate speed of 45 r/min on water bath shaker, the optimum combination of enzyme consists of Onozuka R-10 (0.5%), Hemicellulase (0.8%), Macerozyme R-10 (0.8%), MES (0.1%) and Mannitol (10%) dissolved in CPW solution with pH 4.8. The protoplasts prepared with the methods above are used in subcellular location and the effects show well.
