Waterlogging is a significant abiotic stress that reduces the oxygen supply to roots in rhizosphere, impairing plant growth and development. Cowpea highly sensitive waterlogging, their grain yield affected by genotype stage. Understanding physiological responses of cowpea waterlogging crucial for developing strategies improve crop waterlogged environments. In this two-year field trial, we quantified impact ten days on morpho-physiological attributes, seed components, quality two genotypes...

Increased environmental fluctuations because of climate change have been forecasted in many agricultural regions to increase the frequency, intensity, and duration drought episodes, which threaten sustainability future crop production. Although cowpeas are drought-tolerant, recent evidence shows that soil water stress early stages vegetative growth significantly impairs development, with detrimental impacts on yields. Diversity has extensively genotyped sequenced enhance tolerance based...

Seed germination is the stage in which plants are most sensitive to abiotic stress, including salt stress (SS). SS affects plant growth and performance through ion toxicity, decreasing seed percentage increasing time. Several priming treatments were used enhance under SS. The objectives of this study (1) identify shorten emergence period, (2) evaluate against SS, (3) induce synchronized germination. Salt-sensitive ‘Burpee Bibb’ lettuce seeds treated with 0.05% potassium nitrate, 3 mM...

Lettuce is an economically important crop for small and medium-sized growers. When grown in adverse environmental conditions, lettuce vulnerable to a deterioration of yield quality. Research concerning the impact elevated potassium (K) levels on leafy vegetables, such as lettuce, lacking. Therefore, seeds dark-red ‘Lollo’ were germinated under greenhouse conditions at 25/20 °C (day/night). Plants transferred into 11-L containers placed growth chambers 25 33 °C. with K treatments 117.3...

Waterlogging induces growth and developmental changes in sensitive crops such as cucumber (Cucumis sativus L.) during early plant development. However, information on the physiological mechanisms underpinning response of plants to waterlogging conditions is limited.
