The effects of irrigation water salinity (12 dS m−), imposed at maximum tillering (35−40 days after sowing, DAS) or booting (50−60 DAS) or grain filling (75−85 DAS) stage of wheat, on growth and yield of the crop was demonstrated. The experiment comprised four treatments – I1: irrigation by fresh water (FW) at all three growth stages (control), I2: irrigation by saline water (SW) at maximum til...

abstract silicon (si) is considered one of the beneficial elements for plant, however recent studies show that si plays an important role in plant resistance to environmental stresses , like salinity. an experiment was conducted to study the effect of si and nacl salinity on the growth, yield and fruit quality of strawberry (fragaria × ananassa duch) cv “selva” was grown hydroponically in the c...

Madder (Rubina tinctorum L.) is mainly cultivated in central part of I.R. of Iran that is an arid and desert area with scarce and saline water resources. Its root is used as herbal medicine and food additives and its shoot (top) is used as forage crop. However, little is known about its salinity tolerance and soil water limits for growth. The objectives of the present study were to investigate ...

A new split-root system was established through grafting to study cotton response to non-uniform salinity. Each root half was treated with either uniform (100/100 mM) or non-uniform NaCl concentrations (0/200 and 50/150 mM). In contrast to uniform control, non-uniform salinity treatment improved plant growth and water use, with more water absorbed from the non- and low salinity side. Non-unifor...

abstract seed germination is an important phase of plant development during which soil water availability is crucial. salinity can affect seed germination in two ways: 1) change of osmotic potential of available water, 2) toxicity effects. in this experiment, interactive effects of salinity and water deficit on germination criteria of two species of a, littoralis and a. logopoides were studied ...

Understanding mechanisms of salt tolerance, physiological responses to salt stress, and screening genotypes for breeding programs are important scientific issues remained to be investigated in pistachio. Therefore, current study was carried out to investigate response of different pistachio cultivars (G1, G2, Kaleghochi and UCB1) to salinity treatments (0.6 as control, 10, 20 dS m-1 using salin...

this study was carried out to evaluate the effect of probiotic (bacillus latrospores and bacillus licheniformis) on growth and survival of silver carp larvae (hypophthalmichthys molitrix). rotifers (brachionus plicatilis) were used as live prey vehicle for probiotic transport. they were cultured in sea water with 15 ppt salinity and nannochloropsis oculata microalgae was used as feed. five trea...

kochia (kochia scoparia l. schard) is an annual, halophyte and drought resistant plant that can be irrigated with saline water and a valuable source for forage under drought and saline ecosystem. in order to evaluate the germination characteristic of kochia under different temperatures and salinity stress levels, an experiment was conducted at physiology lab of ferdowsi university of mashhad, i...
