Response and Defence Mechanisms of Vegetable Crops against Drought, Heat and Salinity Stress

Environmental pollution, increasing CO2 atmospheric levels and the greenhouse effect are closely associated with ongoing climate change extreme climatic events we witnessing all over Earth. Drought, high temperature salinity among main environmental stresses that negatively affect yield of numerous crops, challenging world food safety. These effects more profound in vegetable crops which generally susceptible to than field or tree crops. The response single combined stressors involves various changes plant morphology physiology molecular processes. Knowing mechanisms behind these responses may help towards creation tolerant genotypes long-term. However, imediacy problem requires urgently short-term measures such as use eco-sustainable agricultural practices can alleviate negative pollution allow adapt adverse conditions. In this review, abiotic were examined, namely drought, heat stress, focusing on involved most common responses. Moreover, cultural techniques, biostimulants, grafting genomic sequencing increase quality tomato crop under conditions also presented.
