ABSTRACT Salt stress is one of the most limiting environmental factors for agricultural yields in the Semiarid region of Brazil. Considering the expansion of areas with sugarcane crops in this region, the selection of more adapted plant varieties to this environment is an essential tool for the sustainability of this activity. Thus, the objective of the present work was to evaluate the physiological and biochemical responses of plants of ten sugarcane varieties to salt stress. The experiment was conducted in a greenhouse using a randomized block design, in a 6×10 factorial arrangement consisting of six salinity levels in the irrigation water (0, 1.0, 2.0, 4.0, 6.0, and 8.0 dS m-1) and ten sugarcane varieties (VAT 90212, RB 72454, RB 867515, Q 124, RB 961003, RB 957508, SP 791011, RB 835089, RB 92579, and SP 943206), with three replications. Salt waters were applied every two days to increase the soil moisture to field capacity and promote leaching. The gas exchange, chlorophyll content, and total soluble and reducing sugars of leaves were evaluated at 90 days after planting. The highest chlorophyll contents were found in plants of the varieties Q 124, RB 96103, RB 835089, and SP 943206. The effect of salinity on the sugarcane plants affected their leaf gas exchanges and total soluble and reducing sugar contents, denoting the adaptability of plants to the stress conditions evaluated. The decrease of stomatal conductance resulted in decreases in photosynthetic rates in plants of all sugarcane varieties evaluated, except for RB 867515.

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.

Response of Salak Seedlings (Salacca Zallaca) Growth to Dosage of Endomycorrhizal Spore in Quartz Sand and Zeolite Carrier Media. This study aimed to study the effect of endomycorrhizal spore dosage and carrier media that were applied directly to the roots of salak plants. The research designed as factorisl by using Randomized Block Design with 2 treatment factors. The first factor was number of endomycorrhiza spores consists of 4 levels i.e 0, 75, 150, and 225 spores per 500 g carrier media per polybag, while the second factor was the type of carrier media consist of 2 levels i.e zeolite and quartz sand. The results showed that interaction between endomycorrhizal spore dosage with   carrier   media   did   not   significantly   influence   the   growth   of   salak   seedlings. Endomycorrhizal spores in doses of 75, 150 and 225 spores per polybag increased root infection and leaf P nutrient content compared to control, but seed height, leaf area, shoot dry weight, root dry weight and total dry weight of seedlings not significantly difference. The zeolite carrier media caused root infection by mycorrhizal was higher than quartz sand media, but the P nutrient uptake and seedling growth were not significantly different. Based on the results of this study it is necessary to make a longer observation of the effect of endomycorrhizal spore doses and carrier media on the growth of salak seedlings.

ABSTRACT Water deficit in cauliflower cultivation may impair its development and yield. This study aimed to analyze the agronomic performance of cauliflower grown in a protected environment, under different water conditions and silicon (Si) doses. The experiment was arranged in a randomized block design, in a 3 x 4 factorial scheme, with three levels of water replacement [40, 70 and 100 % of the evapotranspiration (ETc)] and four Si doses (0, 50, 100 and 150 kg ha-1), with four replications. Leaf (SPAD index, area, fresh and dry weight), stem (diameter, height, fresh and dry weight) and inflorescence (diameter, fresh weight, dry weight, water content and commercial classification) characteristics were evaluated. The replacement of 40 % of the ETc showed lower results for the SPAD index in the phases II and III, leaf area, leaf and stem fresh weight and inflorescence diameter. The 70 % replacement cultivation showed a yield similar to that of the 100 % of the ETc. The use of Si was beneficial for the productive performance of the cauliflower at all levels of water replacement.

Saline level of water or soil beyond the limit tolerated by crops may impair morphological, physiological, and biochemical processes of plants in general, including tamarind. This problem requires the adoption of management and input techniques to reduce the degenerative effects of salts on plant species. In this sense, the aim of this study was to assess the effect of bovine biofertilizers on biometric variables and chlorophyll contents in tamarind seedlings irrigated with saline water. The experiment was conducted from October 2012 to January 2013, in Areia, PB, Brazil, in a randomized block design with four replications and five plants per plot in a 5 × 3 factorial scheme, consisting of electrical conductivity of water of 0.5, 1.5, 3.0, 4.5, and 6.0 dS m?1 and soil without and with common and chemically enriched biofertilizers. Leaf area, shoot dry matter, and contents of chlorophyll a, b, total, and carotenoids were assessed at 100 days after sowing. The increased water salinity reduced leaf area and seedling biomass formation, with a higher intensity in the soil without biofertilizer. The addition of biofertilizers allows the formation of tamarind seedlings irrigated with water of a salinity not tolerated by them when cultivated in the soil without the tested inputs.
