The Effect of Salicylic Acid on the Growth and Microtuberization of Potato (Solanum tuberosum L.) cv. Arizona Propagated in Vitro
Abstract
Salicylic acid was employed in this study at levels (0, 50, 100, 150, 200 mg/L) in culture media for shoot development from the culture of single nodal segments, the results showed that the level (100 mg/L) was the best significantly in shoot number, leaf number, leaf area, root length and number, the significant effect of (100 mg/L) was also in total soluble protein (16.78 mg/gm) in shoots, whereas the levels (100,150, 200 mg/l) were the best significantly in chlorophyll content of the shoot leaves, the level (100 mg/L) was also affected significantly in the means of microtuber weight and number(1.094), (7.125) and total soluble protein (5.146 µg /gm) whereas the levels (100 and 150 mg/L) of salicylic acid in starch percentage (12.97, 12.99 %) were better significantly than control treatment (2.55 %).
