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.

  • Analysis of Growth and Productivity of Green Chickpea Using Nitrogen and Phosphorus Fertilization
  • Abstract Chickpea contains high levels of protein, vitamins and minerals. Acceptable chickpea yield is the result of meeting nitrogen and phosphorus requirements. The effect of appropriately meeting such requirements reflects on growth and can easily be evaluated using growth analysis. This research determined: (a) The effect of nitrogen and phosphorus fertilization on phenology, net assimilation rate, number of green leaves, leaf area, leaf area index and leaf area duration; (b) Green chickpea yield and number of pods due to fertilization; and (c) The combination of nitrogen and phosphorus fertilization that yields the most net revenue. Nitrogen and phosphorus fertilization was evaluated;… More

  • Rapid Propagation of Rhynchostylis retusa in Vitro
  • Abstract An efficient regeneration system of Rhynchostylis retusa was established to provide technical reference for the application of tissue culture tube seedlings in production. The mixtures of callus and protocorm from aseptic germination were used as explants. The optimal media of each stage was selected for callus proliferation, protocorm occurrence and growth, rejuvenation and rooting via a single, complete combination and orthogonal experiment. The results showed that the optimal medium for callus proliferation, protocorms occurrence and growth was 1/2 Murashige and Skoog (MS) medium adding 50 g·L−1 banana puree, 0.1 mg·L−1 α-naphthaleneacetic acid (NAA), 1.5 mg·L−1 6-benzylaminopurine (6-BA) and 1.0 mg·L−1 More

  • Phenotype Analysis and Fine Mapping of the Male Sterile Mutant ms10 in Rice (Oryza sativa L.)
  • Abstract There is a positive correlation between fertility and yield, and the decrease of fertility is bound to a greatly reduced crop yield. Male sterile mutants can be used in hybrid rice. Therefore, rice male sterility has an important value in research and application, and the study of related mutants is also very vital. The mutant ms10 (male sterile 10) reported in this study was induced by ethyl methane sulfonate (EMS) in the indica maintainer line Xinong 1B. There was no significant difference between the ms10 and wild type in the vegetative growth stage. However, in the reproductive growth stage, ms10 More

  • Effects of Exogenous α-Ketoglutaric Acid on 2-Acetyl-1-Pyrroline, Yield Formation and Grain Quality Characters of Aromatic Rice
  • Abstract The improvement of grain quality in aromatic rice is very important for farmer to increase their income. Present study was conducted with a two-year field experiment and three aromatic rice cultivars in order to study the effects of exogenous α-ketoglutaric acid on yield formation, grain quality characters and the biosynthesis of 2-acetyl-1-pyrroline (2-AP, key component of aromatic rice’s fragrance) in aromatic rice. At heading stage, 0.50 mmol L–1 (T1) and 1.00 mmol L–1 (T2) α-ketoglutaric acid solutions were overhead sprinkle to aromatic rice plants, respectively while the treatment which was overhead sprinkled with distilled water was set as control (CK).… More

  • Character Identification of an Early Flowering Mutant
  • Abstract The concept of gene-function-genetic trait was introduced to explore the effects of early flowering on the growth and development of maize at the jointing stage and to obtain early flowering mutants using ethyl methanesulfonate mutagenesis. First, we studied gene expression, phytohormones, and lignin content to explore the physiological peculiarities of the early flowering mutant. Then we analyzed the genetic features of the mutants during the jointing stage by measuring physiological and biochemical indices of drought tolerance. The results showed that the photosynthetic rate of the mutant was significantly higher than that of the control and the rate of accumulation of… 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
