Physiological and Yield Performance Is Partially Linked to Water Use Efficiency of Eggplant Genotypes in a High-Tech Glasshouse

Eggplant (Solanum melongena L.) has become an increasingly common vegetable grown in glasshouses. This study emphasized on the physiological traits and productivity of three eggplant cultivars (Longa, Lydia, Tracey) a high-tech glasshouse to determine genotypic differences agronomical, morphological, responses. The parameters as well these were evaluated. results showed that Tracey had significantly higher leaf growth than Longa Lydia. exhibited values net CO2 assimilation (A), stomatal conductance (gs), transpiration rate (Tr) Tracey, whereas larger gs, Tr, intracellular concentration (Ci) number flowers per node compared two other varieties, but fruits did not statistically differ among cultivars. Tracy produced highest yield (fruit weight fruit m2) due length expansion despite lowest level A Interestingly, translated into better water use efficiency (WUE) agronomic term, its intrinsic WUE (A/gs) was However, significant correlations between photosynthetic only found certain stages growth. Therefore, further research work with emphasis source sink partitioning large genotypes is required investigate varietal performance greenhouse eggplants. Then, information can be protected cropping set up benchmark for large-scale sustainable production eggplants less consumption horticultural industry.
