Responses ofUlva proliferaandUlva linzato Cd2+stress were studied. We found that the relative growth rate (RGR), Fv/Fm, and actual photochemical efficiency of PSII (Yield) of twoUlvaspecies were decreased under Cd2+treatments, and these reductions were greater inU. proliferathan inU. linza.U. proliferaaccumulated more cadmium thanU. linzaunder Cd2+stress. WhileU. linzashowed positive osmotic adjustment ability (OAA) at a wider Cd2+range thanU. prolifera.U. linzahad greater contents of N, P, Na+, K+, and amino acids thanU. prolifera. A range of parameters (concentrations of cadmium, Ca2+, N, P, K+, Cl−, free amino acids (FAAs), proline, organic acids and soluble protein, Fv/Fm, Yield, OAA, and K+/Na+) could be used to evaluate cadmium resistance inUlvaby correlation analysis. In accordance with the order of the absolute values of correlation coefficient, contents of Cd2+and K+, Yield, proline content, Fv/Fm, FAA content, and OAA value ofUlvawere more highly related to their adaptation to Cd2+than the other eight indices. Thus,U. linzahas a better adaptation to Cd2+thanU. prolifera, which was due mainly to higher nutrient content and stronger OAA and photosynthesis inU. linza.

Abstract Metabolomics can indicate the physiological and biochemical responses of mosquitoes to different stimulants, including insecticides, which allow them to adapt to different inhospitable environments. Though metabolic differences between insecticide-resistant and -susceptible strains have been established for other mosquito species, such as Anopheles and Culex, it is yet to be done for Aedes albopictus (Skuse). In this study, nuclear magnetic resonance (NMR) spectroscopy–based metabolomic analysis performed on Ae. albopictus deltamethrin-resistant and -susceptible strains showed significant differences in amino acid, organic acid, and sugar metabolism. Concentrations of neutral amino acids and sugars tended to be lower in the deltamethrin-resistant strain than in the deltamethrin-suceptible strain, but the concentration of basic and acidic amino acids and organic acids increased. All these changes might accommodate biochemical and physiological needs in deltamethrin-resistant mosquitoes, such as enzyme synthesis and detoxification. This was further confirmed by the predictable draft metabolic map. This is the first report using NMR spectroscopy to investigate the metabolic differences between deltamethrin-resistant and -susceptible strains of Ae. albopictus. To a certain degree, this demonstrates how Ae. albopictus develop insecticide resistance by metabolic reprograming to survive under the insecticide pressure.

Background: Pulses play an important role in Indian agriculture and they are the rich sources of protein. Redgram is an essential food legume, mostly cultivated under rainfed condition in India. Due to increasing population the demand of pulses is increased; hence the redgram productivity has to be increased to meet out the requirement. To overcome this problem an investigation was carried out to study the effect of crop geometry, modified canopy architecture and 1% PPFM application on morpho-physiological and biochemical responses of rainfed redgram during north-east monsoon season. Methods: The treatments comprised of varied crop geometries viz, broad casting (farmer’s practice), high density planting at 30 × 30 cm and recommended spacing of 60 × 30 cm; modified canopy architectures viz. nipping of primary branches at 45 and 60 days after the receipt of soaking rain and foliar application of 1% PPFM spray at 50% flowering to avoid the moisture stress. Result: The results revealed that sowing at 60 × 30 cm spacing with nipping at 45th day recorded significantly higher seed yield and protein yield of redgram in rainfed condition. Further, nipping at 45th day showed higher level of relative water content (51.6%) associated with lower level of proline (26.61 mg g-1).

Corn (Zea mays L.) is one of the most important cereal crops in many countries due to its high nutritive value and a raw material for many industrial products. This research was conducted to determine the optimum concentration of the foliar application of amino acids biostimulants at appropriate growth stage for achieving more efficient use of the foliar application on sweet corn (Zea mays saccharata) var. merkur. The foliar application used in this study was the commercial product (PerfectoseTM, liquid) which is a well known product and commonly used for different crops in Jordan. The experiment was conducted at the greenhouse during the summer of 2015. Corn plants were sprayed with four different concentrations: 1, 2, 3 and 4ml/L at three different growth stages: 7th leaf, tasseling and milk stage, while the control plants were sprayed with distilled water only. The morphological characteristics (plant height, root length and ear length), physiological characteristics (leaf relative water content and leaf water potential), and biochemical characteristics (chlorophyll content, nitrogen, phosphorus, potassium and protein content) were recorded during the experiment. The results indicated that the corn plant height, leaf water potential, chlorophyll content, nitrogen, phosphorus, potassium and protein content were significantly affected by the foliar application treatments, while the rest of the parameters studied were not significant. The treatments 4ml/L at milk stage and 1ml/L and 2ml/L at 7th leaf stage were most effective in the majority of parameters studied. It can be concluded that using foliar application of amino acids biostimulants could positively enhance sweet corn morphological, physiological and biochemical characteristics.

Poplar clone Kranti was selected to assess the morphological, physiological and biochemical responses under drought at different levels of water stress, as it is a common clone used to be grown in Uttarakhand for making paper and plywood. The cuttings of Populus deltoides L. (clone Kranti) were exposed to four different watering regimes (100, 75, 50 and 25% of the field capacity) and changes in physiological and biochemical parameters related with drought tolerance were recorded. Alterations in physiological (i.e. decrease in relative water content) and biochemical parameters (i.e. increase in proline and soluble sugar content and build-up of malondialdehyde by-products) occurred in all the three levels of water stress, although drought represented the major determinant. Drought treatments (75%, 50% and 25% FC) decreased plant height, radial stem diameter, harvest index, total biomass content and RWC in all the three watering regimes compared to control (100% FC). Biochemical parameters like proline, soluble sugar and MDA content increased with severity and duration of stress, which helped plants to survive under severe stress. It was analyzed that for better wood yield poplar seedlings should avail either optimum amount of water (amount nearly equal to field capacity of soil) or maximum withdrawal up to 75% of field capacity up to seedling establishment period (60 days). Furthermore, this study manifested that acclimation to drought stress is related with the rapidity, severity, and duration of the drought event of the poplar species.
