Growth stage-based response of wheat (Triticum aestivum L.) to kinetin under water-deficit environment: pigments and gas exchange attributes

摘要: Plant growth regulator, kinetin, is known to modulate the key physiological processes under abiotic stresses in different crops. However, kinetin-mediated response at stages of crop plants lagging behind. Therefore, a field experiment was conducted appraise potential role exogenously applied kinetin alleviating effects water scarcity on wheat. Three levels (0, 75, and 150 mg/L) were used either as seed treatment or foliar spray vegetative post-anthesis stage. Water deficit markedly reduced shoot fresh mass, plant chlorophyll level, flag leaf photosynthesis, stomatal conductance, transpiration rate. Degradation greater subjected water-deficit conditions. growing continuous conditions had significantly lower concentration b than those treated with stage receiving normal irrigation. Inhibited photosynthes...
