Study of Drought Stress on Aba Accumulation and Proline among in Different Genotypes Forage Corn

摘要

In order to investigate the role of physiological factors, proline and ABA in the drought resistance of forage corn varieties, an experiment was carried out under drought (medium stress and high stress) and control conditions. A split plot design experiment using randomized complete block with four replication was used, so that irrigation treatment was considered as main plots and varieties forage corn as sub plots. Significant difference was found among the varieties at the proline and ABA. Results also indicated that drought stress dose affect different activity levels of proline and ABA. Therefore, selection for drought resistance by evaluation of proline and ABA in these varieties is useful.
