Inoculation of rapeseed under different rates of inorganic nitrogen and sulfur fertilizer: impact on water relations, cell membrane stability, chlorophyll content and yield

Seeds from the maize /Zea mays L./ variety Kneja 310 and landrace B0E0170 were subjected to controlled accelerated aging test (AA) for 72 hours and 120 hours at temperature 41±0.5°C and 100.0% air relative humidity. For the control variant, not subjected to the АА test seeds were used. After AA test, all seed variants were germinated and were used for an analysis of germination energy. The emerging coleoptiles were studied for the presence of anti-oxidative response (MDA, hydrogen peroxide, cell membrane stability), and morphological parameters and relative chlorophyll content were assessed as well as. A vegetation pot experiment was performed with the AA-72h variant and 15-day seedlings were morphologically and physiologically assessed. The aim of the study was to evaluate the relationship between the vitality of the seeds and their stress response to the controlled AA test, which simulated low-temperature storage. The germination rate of seeds and the fresh and dry weight of coleoptiles following ageing treatments were decreased. These results correlated well with the increased accumulation of total hydrogen peroxide and MDA content and the decrease of cell membrane stability. Negative changes were observed in chlorophyll content index, fresh and dry weight and leaf area of 15-day seedlings in pot trial. It was concluded that the controlled accelerated ageing could be used as a model for estimation of seed deterioration in maize after long-term storage.

Soybean Genotypes

An experiment was conducted in a venylhouse at the environmental stress site of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during September to December 2012 to study the effect of drought stress on proline content, soluble sugar content, chlorophyll content and cell membrane stability of soybean genotypes. Four studied genotypes viz., Shohag, BARI Soybean-6 and BD2331 (relatively stress tolerant) and BGM2026 (susceptible) were tested against two water regimes such as water stress and non-stress. Results indicated that due to drought stress there was an increase in proline content and soluble sugar content and decrease in chlorophyll a content, chlorophyll b content, total chlorophyll content, chlorophyll a/b ratio and cell membrane stability. Proline and soluble sugar showed more content in tolerant genotype than in susceptible ones. Chlorophyll reduction was most significant and cell membrane stability was found minimal in susceptible genotypes. From the result, genotype BGM2026 which recorded the lowest proline, soluble sugar content and highest chlorophyll reduction and cell membrane injury was considered as drought susceptible. The variety/genotype of soybean such as BARI Soybean-6, Shohag and BD2331 were more drought stress tolerant and better mechanisms of drought tolerance.Bangladesh J. Agril.
