Title

Stepwise Regression Analysis of Citrus Genotype Under Cold Stress

Pages

  00-00

Abstract

 Background: Citrus is among the cold temperature (freezing) susceptible plants. The performance of storage and breeding of horticultural crops is mainly dependent on the correlation among the traits. Objectives: The present study was conducted to identify the physiological and biochemical traits of some Citrus cultivars with the greatest influence on Stress Tolerance and determine the direct and indirect effects of these traits on the median Lethal Time (LT50) using integrated pathway analysis (i. e., Stepwise Regression and causality coefficient). Methods: Pathway analysis (i. e., Stepwise Regression and causality coefficient) based on additive models, which is among the robust statistical methods to describe the relationship among the traits, was used to investigate the physiological and biochemical charac, teristics of four Citrus cultivars (i. e., Japanese mandarin, Thomson orange, Ruby Star grapefruit, and Lisbon lemon) at temperature levels (-8,-4, and +4°, C) in a completely randomized design with three replications in 2021. Results: The results showed that Japanese mandarin and Thomson orange cultivars had the highest Stress Tolerance (LT50). The results of the correlation coefficient demonstrated that the highest positive and significant correlations belonged to the LT50 with total flavonoid (0. 443**), chlorophyll a with chlorophyll b (0. 613**), carotenoid with chlorophyll a (0. 929**), chlorophyll b (0. 573**), and total chlorophyll (0. 849**), relative moisture content with malondialdehyde (0. 559**), glycine-betaine with catalase (0. 919**), hydrogen peroxide with total flavonoid (0. 405**), and catalase (0. 611**). Conclusions: The results of Stepwise Regression for all traits indicated the importance and critical role of total flavonoid, proline, and LT50 characteristics.
