Response of Seed Yield, Its Components, Chlorophyll Content and Proline Concentration of Mung bean (Vigna radiate L.) To Apply Sulphate Potassium Fertilizer under Salinity Stress Situation
BACKGROUND: Among the environmental stresses soil salinity is a widespread environmental problem that has been found to affect more than 77 million hectares or 5% of the cultivable land of the universe. Potassium has a positive role in plant growth under saline conditions, because this element plays an essential role in photosynthesis, osmo regulatory adaptations of plant to wa...
متن کاملEffects of Growth Stimulator Microbes on Growth and Ions Concentration of Stevia under Salinity Stress Conditions
Soil salinity and water deficit are major problems for development of agricultural production. In this study, effects of growth promoting microorganisms (inoculation with Piriformospora indica and two isolates of Streptomyces sp.) on the leaf yield and absorption rate of some elements in leaves and roots of stevia plant was investigated under salinity conditions for two consecutive years (2016-...
متن کاملEffect of Nitrogen and Phosphorus Bio Fertilizers on Some Seed Germination Traits of Two Cultivars of Quinoa under Salinity Stress
Introduction: salinity is known as the most important inhibitor of seed germination of most plants and limits the establishment of plants in arid and semi-arid regions such as Iran. The first effects of salinity on plant growth are associated with reduced seed germination and lack of uniformity in plant emergence. Currently, identification and utilization of tolerant cultivars are one of the mo...
متن کاملThe impact of salt stress on antioxidant enzymes, photosynthetic pigments, protein and proline content of Fig cultivars (Ficus carica.L)
The fig, a sub-tropical crop, consumes as a table fruit as well as a dry product. Since, salinity is the serious concern of fig production, during 2016-2018, seven fig cultivars (‘Sabzʼ, ‘Siyahʼ, ‘Shah Anjirʼ, ‘Atabakiʼ, ‘Kashkiʼ, ‘Matiʼ and ‘Barʼ) were subjected to saline water (0.5, 2, 4, 6, 8 and 10 dSm-1). Then, potein, proline, photosynthetic pigments, superoxide dismutase, catalase, guaia...
متن کاملEffect of salinity stress on some physiological characteristics and photosynthetic parameters of several Iranian commercial pomegranate genotypes
In order to evaluate the salinity tolerance of six pomegranate genotypes including Malas Dane Ghermez Esfahan, Malas Yazdi, Shirin Shahvar, Meykhosh Yazd, Malas Saveh and Malas Yousofkhani, a greenhouse experiment was conducted as a factorial based on randomized complete block design with five salinity levels of 0, 25, 50, 75 and 100 mM sodium chloride at Agricultural College of Lorestan Univer...
متن کاملEffect of biostimulants on water content and micronutrients and macronutrients of Puccinellia distans under salinity stress
Abstract: Biostimulants are a variety of compounds of plant and animal origin that are used to improve the quality of plant growth. In this study, which was conducted in 1399, the effect of commercial biostimulant Algabon®, algal biostimulant [seaweed extract (SWE)], and namid (amino acid biostimulant) on the plant Puccinellia distans to reduce the effects of salinity stress by improving growt...
