The Fig (Ficus carica.L) is a woody perennial crop, cultivated worldwide in subtropical regions. Since, salinity is the main concern of fig industry, therefore, studying the pattern of ion absorption and accumulation contribute during the stress in different plant organs can lead understanding the mechanism of tolerance/sensitivity. So, during 2016-2017, seven fig cultivars (‘Sabzʼ, ‘Siyahʼ, ‘S...

water salinity and drought are the major abiotic stresses limiting turf grass growth. on the other hand, shortage of waterresources and salinity of water and soil in the arid and semi-arid zones such as iran, are the restricting factors in developinglawn turf grasses. an experiment was conducted to evaluate the combined effects of water salinity and deficit irrigation ontall fescue (festuca aru...

The effects of irrigation water salinity on growth, chlorophyll contents, proline and nutrients accumulation and K/Na ratio in three walnut cultivars was investigated. Three irrigation water salinity levels with electrical conductivities of 1,5, 3, and 5.0 dS/m and tap water as a control treatment were used in a randomized design with four replications. Irrigation practices were realized by con...

the possible alleviating effects of salicylic acid on protection of cowpea (vigna unguiculata) cv. parastu under water stress conditions were investigated in the university of zanjan agriculture research station during 2008. water stress was imposed by withholding irrigation at 50% flowering (flowering water stress, fws) and when 50% of the pods grew 2-3cm (pod-formation water stress, pfws). sa...

introduction: in iran, tuberose is ranked the forth after gladiolus, rose and carnation. these flowers are known as high quality products among which maximum exportation belongs to tuberose and gladiolus. in plant cultivation and development, adequate provision of nutrients is of crucial importance. tuberose needs plenty of nutrients to obtain the desirable quality and flowering. hence, tuberos...

drought is one of the most important factors limiting growth and yield in many parts of the world. in order to evaluate the effects of drought stress on some morphological and physiological traits of two cultivars of bean, two red beans (derakhshan and goli) in four drought treatments including 25%, 50%, 75%, control 100% field capacity were studied in a factorial experiment based on complete r...

development of a green belt with suitable plant species around the source of emission can mitigate the atmospheric contamination. selection of such plant species are required to combat air pollution based on their tolerance level. present study was undertaken to evaluate the tolerance level of higher plants in east of esfahan city, iran, during 2011 in terms of assessing air pollution tolerance...

effect of seed priming by salicylic acid and application of controlled water stress in flowering stage on some physiological characters such as relative water content, chlorophyll index, photosynthetic rates, transpiration rates, stomatal conductance, and leaf internal co2 concentration was investigated on cowpea (vigna unguiculata l. cv. parastoo) plants. experiment was done as a split block d...
