Research into extreme drought tolerance in resurrection plants using species such as Craterostigma plantagineum, C. wilmsii, Xerophyta humilis, Tortula ruralis, and Sporobolus stapfianus has provided some insight into the desiccation tolerance mechanisms utilized by these plants to allow them to persist under extremely adverse environmental conditions. Some of the mechanisms used to ensure cell...

Drought is considered one of the most acute environmental stresses presently affecting agriculture. We studied the role of exogenous glutathione (GSH) in conferring drought stress tolerance in mung bean (Vigna radiata L. cv. Binamoog-1) seedlings by examining the antioxidant defence and methylglyoxal (MG) detoxification systems and physiological features. Six-day-old seedlings were exposed to d...

It was reported that Nuclear Factor Y (NF-Y) genes were involved in abiotic stress in plants. Foxtail millet (Setaria italica), an elite stress tolerant crop, provided an impetus for the investigation of the NF-Y families in abiotic responses. In the present study, a total of 39 NF-Y genes were identified in foxtail millet. Synteny analyses suggested that foxtail millet NF-Y genes had experienc...

using plant growth regulators at the stresses environment can improve plant growth and crop production. hence, in this research response of photosynthesis rate, chlorophyll, soluble sugar and flower dry weight of chamomile to methyl jasmonate under different salinity levels was studied. values of 0 (control), 75, 150, 225 and 300μm methyl jasmonate (meja) with salinity levels of 2, 6, 10 and 14...

A greenhouse experiment was conducted to evaluate the comparison of nutrient use efficiency, antioxidant assay, and nutritional quality butter-head lettuce in five cultivation systems. For this experimental study, a split-boxes arrangement completely randomized design (CRD) with three aeroponics systems (high pressure (T1), low (T2), ultrasonic nozzle (T3)), hydroponic system (T4), conventional...

Aims: This objective of this work was to evaluate the effects water deficiency on physiological aspects oiticica plants, as well capacity potassium fertilization attenuate such effects.
 Study Design: The treatments were distributed in an entirely randomized design (DIC), consisting a 4x4 factorial, with four levels (K) and turning, five repetitions.
 Place Duration Study: experiment ...

abstract three pear genotypes (nazkeh, lasoreh and qevilah), grown in 2l containers, were studied under four irrigation regimes in order to evaluate the leaf relative water content (rwc), photosynthesis, leaf gas exchanges and plant dry weight induced by water stress. control treatment everyday was irrigation. irrigation was practiced when soil water potential reached at -0.4, -0.8, and -1.2 mp...

The effects of potassium fertilizer (K2SO4) levels K0, (0), K1,(150) and K2,(250 kg/ha) in two species of Brassica napus (Hyola 401 Hybrid) and Brassica juncea (landrace cultivar), under three irrigation regimes, control (irrigation after 50%,), moderate stress, (irrigation after 70%), and severe stress (irrigation after 90% soil water depletion) were studied in a factorial experiment laid out ...

Water plays a crucial role in maintaining plant functionality and drives many ecophysiological processes. The distribution of water resources is continuous change due to global warming affecting the productivity ecosystems around globe, but there lack non-destructive methods capable monitoring leaf content that would help us understanding consequences redistribution water. We studied utilizatio...

Salinity is the second major obstacle after drought conditions that hinder high productivity of plants. Many factors contribute to salinity problem, consequently affects plant physiology, growth as well production. Therefore, this research aims determine effects betaine-rich Nano fertilizer on physiological parameters sweet corn (Z. mays var. saccharata) and A. thaliana under salt stress. In st...
