Abstract:
Climate change has significant devastating effect on abiotic stress in vegetable production. Vegetable cropping systems must have high resilience to climate change, so that production practices can achieve economic profitability and environmental sustainability. Different abiotic stress including flooding, drought and extreme temperatures have drastic effect towards vegetable crop production leading to reduced yield potential of vegetable crops are photoperiod reduction, water availability and poor vernalization leading to total crop failures. Recent researches infer that adaptation to counteract environmental stresses and improving the tolerance can be possible through alteration of the root system through grafting over selected vigorous rootstocks. Some of the successful achievements include grafting of Bitter melon (Momordia charanthia) cv. New Known on rootstock of Luffa (Luffa cylindria Roem) cv. Cylinder leading to flooding tolerant genotype. Similarly, drought resistance have been achieved by grafting Tomato (Solanum lycopersicum) cv. M28 scion with Tomato (Solanum lycopersicum) cv. Beaufort rootstock. Besides there are evidences of mitigating thermal stress through grafting of Cucumber (Cucumis sativus) cv. Jinyan No. 4 scion with Figleaf Guard (Cucurbita ficifolia) and Luffa (Luffa cylindrica) cv. Xiangfei rootstock. Salinity tolerance has also been achieved by grafting Cucumber (Cucumis sativus L.) cv. Jinchun No. 2 scion with Pumpkin (Cucurbita moschata Duch.) cv. Chaojiquanwang rootstock. Therefore in this context, vegetable grafting has been reported to be highly efficient, eco-friendly plant surgical technique for development of climate resilience crop production in order to combat with different abiotic stress.
