Morphophysiological and yield attributes of groundnut varieties under different salinity stress conditions

The study sought to evaluate the response of three groundnut genotypes (Binachinabadam-3, Dacca-1 and Zhingabadam) to various salt concentrations (D0 – Control, D1 – 2.5 dS/m, D2 – 5.0 dS/m, D3 – 7.5 dS/m, D4 – 10.0 dS/m, D5 – 12.5 dS/m) through observation of morphological and physiological characters. Based on relative performance of yield contributing characters and nutrient contents of leaves and stem, Binachinabadam-3 emerged to be a tolerant variety and based on root shoot characters, Dacca-1 appeared as tolerant while Zhingabadam always performed as sensitive variety. Salinity treatments had most adverse effects at flowering stage and followed the trend of sensitivity as flowering stage > vegetative stage> pre sowing stage > pod filling stage. All varieties were found to be tolerant up to salinity level of 7.5 dS/m.

AbstractPlant bioregulators (PBRs) represent low-cost chemicals for boosting plant defense, especially under stress conditions. In the present study, redox based PBRs such as thiourea (TU; a non-physiological thiol-based ROS scavenger) and hydrogen peroxide (H2O2; a prevalent biological ROS) were assessed for their ability to mitigate NaCl stress in rice variety IR 64. Despite their contrasting redox chemistry, TU or H2O2 supplementation under NaCl [NaCl + TU (NT) or NaCl + H2O2 (NH)] generated a reducing redox environment in planta, which improved the plant growth compared with those of NaCl alone treatment. This was concomitant with better K+ retention and upregulated expression of NaCl defense related genes including HAK21, LEA1, TSPO and EN20 in both NT and NH treated seedlings. Under field conditions, foliar applications of TU and H2O2, at vegetative growth, pre-flowering and grain filling stages, increased growth and yield attributes under both control and NaCl stress conditions. Principal component analysis revealed glutathione reductase dependent reduced ROS accumulation in source (flag leaves) and sucrose synthase mediated sucrose catabolism in sink (developing inflorescence), as the key variables associated with NT and NH mediated effects, respectively. In addition, photosystem-II efficiency, K+ retention and source-sink relationship were also improved in TU and H2O2 treated plants. Taken together, our study highlights that reducing redox environment acts as a central regulator of plant’s tolerance responses to salt stress. In addition, TU and H2O2 are proposed as potential redox-based PBRs for boosting rice productivity under the realistic field conditions.

An experiment was conducted at the net house of Department of Agronomy, Bangladesh Agricultural University, Mymensingh from July to December 2012to investigate the ameliorative effect of green manure and gypsum application on the yield of transplant Aman rice variety BRRI dhan40 under various levels salinity stress. Sodium chloride induced salinity was imposed at tillering stage of plant development. The levels of salinity were 0, 25 and 50 mM NaCl. Green manure @ 0, 5 and 10 t ha gypsum @ 0 and 1 g kg-1 and 1 soil were applied to ameliorate the salinity stress effect. 1 g kg-1 soil were applied to ameliorate the salinity stress effect. Results revealed that the different levels of salinity had significant adverse effect on plant height, number of tillers hill-1, number of effective tillers hill-1, number of ineffective tillers hill-1, 1000-grain weight, grain yield, biological yield and harvest index (HI). All the plants were affected badly when they were exposed to salinity level of 50 mM NaCl. Application of green manure and gypsum helped them ameiorate salinity either individually or in combination at all salinity levels. Grain yield reduction at 50 mM salinity level was 38.64% compared to control which was minimized to 19.04% by the application of green manure @ 10 t ha-1. Grain yield reduction was also minimized from 37.08% to 27% at the same level of salinity by the application of gypsum@ 1 g kg-1soil. Similar amelioration effect was also observed in case of straw yield. The amelioration was improved further when both green manure and gypsum were applied. Without any salinity stress grain yield was 4.49 t ha-1, which was reduced to 2.61 t ha-1 (41.87% reduction) when the crop was stressed with 50 mM salinity. Application of green manure @ 10 t ha-1 and gypsum @ 1 g kg-1 soil improved grain yield to 4.00 t ha-1, where yield reduction was just 10.91%. Similar improvement was also found in straw yield. The results of the study conclude that salinity stress in transplant Aman rice var. BRRI dhan40 could successfully be ameliorated through application of green manure@ 10 t ha-1 and gypsum@ 1 g kg-1 soil.Bangladesh Agron. J. 2014, 17(1): 1-10
