Summary

Ensuring food security for the increasing population is one of the challenges for next decades. As frontiers of crop production, plant physiologists are the most responsible for the improvement of crop production steadily. However, there are several challenges which hindering crop production which includes various abiotic and biotic stresses as loss of soil productivity and natural biodiversity. With the present global climatic change, these abiotic stress factors are taking place more frequently than earlier times leading to the vulnerability of crop productivity, and creating challenges for the farming community to feed the ever-growing population of this universe. Exploring the physiological bases of plant stress tolerance is very important in developing plant stress tolerance. To address this issue researchers are working in understanding the physiological and molecular mechanisms of abiotic stress responses and tolerance. A remarkable progress has also been made in developing crop varieties tolerant to environmental stress. This special issue is indented to bring together a galaxy of eminent experienced scientists to present latest developments in this field.

  • Epi-Brassinolide Positively Affects Chlorophyll Content and Dark-Reaction Enzymes of Maize Seedlings
  • Abstract Brassinosteroids participate in many physiological processes in plants; however, their regulatory roles on the activities of the enzymes involved in dark phase of photosynthesis remains elusive. In this study, detached leaves and protoplasts of maize seedlings were treated with epi-brassinolide (EBR) and brassinazole followed by the determination of the contents of chlorophyll (a+b) and soluble sugars, and the activity of dark reaction enzymes and the expression of the relevant genes. The results showed that chlorophyll (a+b) content increased by 7.4% under 0.1 μM EBR treatment for 48 h; furthermore, chlorophyll (a+b) content increased by 34% in detached leaves that were… More

  • The Enhancement of Soil Fertility, Dry Matter Transport and Accumulation, Nitrogen Uptake and Yield in Rice via Green Manuring
  • Abstract Readily available chemical fertilizers have resulted in a decline in the use of organic manure (e.g., green manures), a traditionally sustainable source of nutrients. Based on this, we applied urea at the rate of 270 kg ha−1 with and without green manure in order to assess nitrogen (N) productivity in a double rice cropping system in 2017. In particular, treatment combinations were as follows: winter fallow rice-rice (WF-R-R), milk vetch rice-rice (MV-R-R), oil-seed rape rice-rice (R-R-R) and potato crop rice-rice (P-R-R). Results revealed that green manure significantly (p ≤ 0.05) improved the soil chemical properties and net soil organic carbon… More
