BACKGROUND AND AIMS Although mangroves have been extensively studied, little is known about their ecological wood anatomy. This investigation examined the potential use of vessel density as a proxy for soil water salinity in the mangrove species Rhizophora mucronata (Rhizophoraceae) from Kenya. METHODS In a time-standardized approach, 50 wood discs from trees growing in six salinity categorie...

in order to evaluate the effect of different levels of salinity and three nitrogen nutrition on biochemical reactions and changes in dry weight of shoot and root on psyllium (plantago ovata f.), a glasshouse experiment in a complete randomized design with three replications in 2009 at university of zabol was conducted. salinity treatments in this experiment were 0, 100 and 200 mm of nacl and ni...

Salicylic acid can mitigate the impacts of salinity and drought stresses in crops. To study the effect of salicylic acid under iso-osmotic drought and salt stresses on nutrients absorption and growth of linseed (Linum usitatissimum L.), an experiment was conducted based on a completely randomized design with three replications in Yasouj University in 2016. Treatments included salinity and droug...

The aim of the present project is to investigate the effect of salinity on growth, biochemical parameters and fatty acid composition in six varieties of safflower as well as identification of stress tolerant variety under saline (8 d Sm) condition. It was observed that salinity significantly decreased the dry weight and fresh weight of safflower varieties. Nitrate reductase (NRA) and nitrite re...

Salinity is an abiotic stress factor that can cause significant crop yield losses. Nitrogen (N) is an essential plant element that is usually limited in most agricultural soils. Recently, incorporation of additives such as N-(n-butyl) Thiophosphoric triamide (NBPT) and Dicyandiaminde (DCD) into N fertilizers has been done with the purpose of increasing N use efficiency of crops. To our knowledg...

Salinity is one of the most important constrain affecting crop growth and productivity. Hence studying salinity at morphological and biochemical point of view has become the basis for understanding salinity and plant interactions. Under stress, plants survive by enhancing the osmolyte accumulation by complex metabolic activities. Present investigation deals with the effect of salinity on growth...

A pot experiment was conducted during 2010-11 in the Department of Agriculture Botany Janta P.G. College Ajeetmal, Auraiya(U.P.), India. Eight genotypes of wheat are selected with varying in their salt tolerance level, to evaluate effect of salinity on germination, growth, and yield related parameters. Lower salinity (3dsm -1 ) did not affect the germination, growth and yield attributing parame...

The effect of salinity and nitrogen on yield, vitamin C, citric acid and nutrient distribution of tomato in hydroponics culture was investigated. Tomato seeds were first let germinate in yonolit pots with wet coco peat and then their seedlings were transferred to plastic tanks containing 5 liters nutrient solution. Treatments were three levels of salinity (0, 30 and 60 mM as NaCl and CaCl2) and...

In this study, the effects of salinity stress (NaCl) on the activity of Catalase (CAT), Guaiacol Peroxidase (POD), and Superoxide dismutase (SOD) were studied in leaves of fifteen oilseed rape (Brassica napus L.) cultivars (Champlain, Hayola401, Licord, Modena, NK Aviator, NK Karibik, NK Octan, Okapy, Opera, PF, RGS, RNX 3621, SLM046, Talayeh, Zarfam). Plants were grown in a greenhouse under co...

An experiment was conducted for a period of eight weeks under laboratory conditions to determine the effect of different salinity levels on the survival and growth of crablings of mud crab, Scylla serrata. The different salinity levels tested were: 5 ppt, 10 ppt, 15 ppt, 20 ppt and 25 ppt. The differences in growth increment in terms of body weight (BW) were significant (p<0.05) among different...
