“…Such behavior is possibly related to the reduction of seed imbibition capacity as the water salinity level increases, because Sousa et al, 2010Sousa et al, , 2014. However, the higher the level of severity of the salt stress, the greater the dependence of plant development on genetic factors such as plant species, cultivar and phenological stage (Correia et al, 2009;Sousa et al, 2014;Sá et al, 2017). The increase in water salinity from 0.5 to 3.5 dS m -1 reduced the root dry mass accumulation of the peanut plants regardless of the genotype studied, causing a percentage reduction of 56.3% ( Figure 3A).…”

“…Peanut plants were grown in lysimeters with capacity for 0.5 dm 3 of substrate, until 30 days after sowing (DAS). The substrate for seedling production was composed of soil collected from the A horizon of an Ultisol (Lima et al, 2017) and commercial substrate (TOP Plant®) in 1:1 proportion on volume basis, respectively, which were characterized according to the methodology of Donagema et al (2011) (Table 1). For sowing, four seeds were distributed in each lysimeter, totaling eight seeds per treatment.…”

This study aimed to evaluate the emergence, growth, biomass accumulation and tolerance of peanut genotypes under salt stress. The experiment was conducted in a protected environment (greenhouse), evaluating six peanut genotypes (Tatuí, L7151, Caiapó, IAC8112, IAC881 and Havana), which were subjected to two levels of irrigation water salinity (0.5 [control] and 3.5 dS m-1), arranged in a 6 x 2 factorial scheme, in a randomized block design, with five repetitions, with two plants per plot. Plants were cultivated for 30 days after sowing in lysimeters with capacity for 0.5 dm3, filled with a mixture of non-saline, non-sodic soil and commercial substrate in 1:1 proportion on volume basis. During this period, plants were evaluated for emergence, growth, biomass accumulation, tolerance to salinity and dissimilarity. The genotypes Tatuí and L7151 are the most sensitive to salt stress in the emergence stage. Irrigation with high-salinity water reduced the growth and biomass accumulation of the peanut genotypes, and Caiapó and IAC8112 were the least affected. The classification of salinity tolerance had the following sequence: Caiapó > IAC8112 > Havana > Tatuí > IAC881 > L7151.

“…At 120 DAT, gas exchanges were measured in the plants using a portable photosynthesis meter (LCPro+ -ADC BioScientific Ltd), operating with controlled temperature of 25 o C, irradiation of 1200 µmol photons m -2 s -1 and CO 2 from the environment at 3 m height from soil surface, to obtain CO 2 assimilation rate (A) (µmol m -2 s -1 ), transpiration (E) (mol of H 2 O m -2 s -1 ), stomatal conductance (gs) (mmol of H 2 Om -2 s -1 ) and internal CO 2 concentration (Ci), in the third leaf from the apex. These data were used to calculate intrinsic water use efficiency (WUEi) (A/E) [(µmol m -2 s -1 ) (mol H 2 O m -2 s -1 ) -1 ] and instantaneous carboxylation efficiency (EiCi) (SÁ et al, 2017).…”

“…In semi-arid regions, there is a predominance of tropical soils with low natural availability of phosphorus and such lack requires greater caution with respect to phosphate fertilization management in these regions because the low availability of the nutrient associated with the water limitations found negatively affect crop development (LIMA et al, 2017;SÁ et al, 2017).…”

This study aimed to evaluate the growth and physiology of Annona squamosa seedlings under increasing irrigation depths and phosphorus doses. The experiment was conducted in protected environment, evaluating five irrigation depths and four P 2 O 5 doses, arranged in 5 x 4 factorial scheme, in randomized blocks, with four replicates and one plant per plot. Treatments were irrigation depths of 60, 80, 100, 120 and 140% of the real evapotranspiration of the seedlings -ETr and phosphorus doses of 0, 350, 700 and 1050 mg dm -3 of P 2 O 5 -. Plants were evaluated at 120 days after transplanting with respect to growth, gas exchanges, leaf water potential and total dry matter accumulation. Phosphorus dose of 350 mg dm -3 promotes satisfactory dry matter accumulation for A. squamosa seedlings, especially under 100% ETr irrigation. Leaf water potential and gas exchanges of A. squamosa are affected by water stress, through both lack and excess of water. Stomatal conductance is the variable most sensitive to the lack of water, whereas photosynthesis and water use efficiency are the most sensitive to the excess of water. Irrigation depth of 100% ETr is ideal to produce A. squamosa seedlings, but the irrigation depth of 80% ETr can be used to produce these seedlings, disregarding small losses of growth.

“…[2,3] Of all the stressors soil and water salinity inflict more on plant development especially in semiarid and arid regions. [4] In order to cope up with these unfavorable conditions, mangrove switch on to different modifications at morphological, physiological, biochemical and molecular levels. [5] Production of secondary metabolites is one of such physiological change which tends the plant to protect themselves against harmful microorganisms along with grazing threat.…”

Objective:To determine the seasonal and geographical impact on plant secondary metabolite production and antimicrobial activity.Methods: Three mangrove plants viz., Ceriops tagal, Bruguiera cylindrica and Lumnitzera racemosa commonly found in Gilakaladindi and Malakayalanka regions of Krishna Estuary, Andhra Pradesh, India were selected for the present study. The study was done during 2014-15 summer, rainy and winter in both the stations. Leaf samples were extracted with methanol and subjected to preliminary phytochemical screening. The methanolic leaf extracts were tested against bacterial pathogens Bacillus cereus, B. subtilis, Staphylococcus aureus, Escherichia coli and a fungal pathogen Candida albicans. Results:The methanolic extracts of leaves collected during rainy season showed maximum zone of inhibition at both the stations Gilakaladindi and Malakayalanka. Among the studied plants leaf methanolic extract of C.tagal was recorded maximum antibacterial activity against B. subtilis and B. cereus (18±0.05 mm), followed by Bruguiera cylindrica both at Gilakaladindi and Malakayalanka respectively. But the extracts of L.racemosa showed less inhibition activity (7±0.00 mm) in all the seasons at both the stations. Conclusion:The study demonstrated that mangroves produce bio-active compounds optimally in rainy season that are effective against microbial proliferation which may further help in synthesis of natural antibiotics in place of commercial antibiotics to heal infectious diseases.
