Kinnow Plants (Citrus nobilis x Citrus deliciosa) Disease-Induced Alterations in Biochemical Composition: A comparison of Healthy and Gummosis-Infected Plants

DOI: 10.22161/ijeab.112.9

Abstract:
A economically significant citrus cultivar, the Kinnow mandarin (Citrus nobilis x Citrus deliciosa) is grown extensively throughout the Indian subcontinent, especially in northern india. In Rajasthan state, Kinnow is mainly produced in Sri ganganagar and Hanumangarh district. Kinnow plants affected by some diseases like; Citrus canker, Phytophthora, Greening (Huanglongbing), Gummosis, Citrus scab, Black fly infestation, Dieback, Anthracnose and sooty mold. Disease management is more important for decrease losses of fruit yield. A comparative analysis of the chosen biochemical parameters between healthy and diseased plants was attempted in the current study. Gummosis-infected Kinnow plants (Citrus nobilis x Citrus deliciosa) show notable biochemical alterations, according to the study, including higher concentrations of Alkaloids compounds, Phenolic, Terpenoids, Proline, MDA (Malondialdehyde) and ROS (Reactive oxygen species) and lower Chlorophyll content. According to these alterations, the disease caused a complex response in the plants that impact both primary and secondary metabolism.

Keywords:
