5-aminolevulinic acid induces regulation in growth, yield and physio-biochemical characteristics of wheat under water stress

The production of wheat crop is below average in many regions of the world which is ascribed to adverse environmental conditions including drought stress. The present study was conducted to appraise the beneficial role of exogenouslyapplied 5-aminolevulinic acid (ALA) on growth, yield and some key...

The present study was conducted to appraise the beneficial role of exogenouslyapplied 5-aminolevulinic acid (ALA) on growth, yield and some key physio-biochemical characteristics of two commercially important wheat cultivars (Shafaq-06 and Uqab-2000) under well watered [100% field capacity (FC)] and water-deficit (60 and 80% FC) conditions.

Foliar spray of ALA at the rate of 50, 100 and 150 mg/L along with control (no spray (NS) and/or water spray (WS)) significantly enhanced chlorophyll a and b pigments, qN, NPQ, qP, K+, Ca2+ and P accumulation in both roots and shoots, proline, GB, total phenolics and malondialdehyde (MDA) contents and yield. The wheat Shafaq-06 was better in shoot dry weight, qN, NPQ and Fv/Fm, shoot and root K+, root Ca2+, proline, GB accumulation and yield attributes, while Uqab-2000 was better in chlorophyll a contents, root P and MDA contents. Overall, better growth and yield of Shafaq-06 than Uqab-2000 under water deficit regimes was found to be associated with ALA improved leaf fluorescence (qN, NPQ and Fv/Fm), shoot and root K+, root Ca2+, proline and GB accumulation.
