Caper is a multi-purpose halophytic plant growing in semi-arid or arid environment. The present study aims to evaluate the effect of different salt ratios of CaCl2 to NaCl on antioxidant defense system, photosynthesis pigments and morphophysiological parameters of caper under drought stress. Predictive regression modeling, principal component analysis (PCA), Pearson's correlation and path analysis were implanted to explore the possible relationships among inter correlated variables and understanding the possible mechanisms. Based on the PCA results, caper had a highest shoot and leaves growth, content of pigments, proline and antioxidant enzymes (peroxidase, superoxide dismutase, catalase, and ascorbate peroxidase) activity and the lower leaf tissue density at the salt ratio of 1:3 (CaCl2:NaCl) under 75% FC. Predictive equation models with high significant R2 were developed for the estimation of antioxidant enzymes activity and proline content (>0.94) as well as pigments (>0.58) were developed. Path analysis studies indicated that proline is the most important regressor (significant positive effect) in four antioxidant enzymes activities while in the case of chlorophylls, leaf tissue density was the most effective variable (significant negative). It was found that caper has a better performance under moderate to high NaCl-salt stress and mild droght stress. Moreover, the network of inter correlated variables revealed that there is a close relationship between antioxidant defense system, pigments and morpholoigical parameters of caper under stress condition. The results of this study would be a useful guide for caper producers as well as plant ecophysiological researchers.

Capparisspinosa L. (caper) is a halophytic plant that grows in semi-arid or arid environments. The current study used an integrated experimental and computational approach to investigate the network of inter-correlated effective variables on the activity of antioxidant enzymes, proline, and photosynthetic pigments in stressed caper. To investigate the possible relationships among intercorrelated variables and understand the possible mechanisms, predictive regression modelling, principal component analysis (PCA), Pearson's correlation, and path analysis were implemented. PCA successfully discerned different salt ratio- and drought-specific effects in data in the current study, and treatments with higher growth indices are easily recognizable. Different salt ratios did not have a significant effect on the activity of four antioxidant enzymes, proline and photosynthesis pigments content of caper. While at the mean level, the activity of four antioxidant enzymes of SOD, POD, CAT, and APX significantly increased under drought stress by 54.0%, 71.2%, 79.4%, and 117.6%, respectively, compared to 100% FC. The drought stress also significantly increased the content of carotemoid (29.3%) and proline (by 117.7%). Predictive equation models with highly significant R2 were developed for the estimation of antioxidant enzyme activity and proline content (> 0.94) as well as pigments (> 0.58) were developed. Path analysis studies revealed that proline is the most important regressor in four antioxidant enzyme activities, while leaf tissue density was the most effective variable in the case of chlorophylls. Furthermore, the network of intercorrelated variables demonstrated a close relationship between caper's antioxidant defence system, pigments, and morphological parameters under stress conditions. The findings of this study will be a useful guide to caper producers as well as plant ecophysiological researchers.
