Introduction: Drought stress is the most influential factors affecting crop yield particularly in irrigated agriculture in arid and semiarid regions. Drought, being the most important environmental stress, severely impairs plant growth and development, limits plant production and the performance of ...

Fennel (Foeniculum vulgare) is one of the most important medicinal plants with many usages in medical, food and cosmetic industries. Development method of two early and medium maturity synthetic cultivars of fennel with the aim of drought tolerance is discussed. The synthetic cultivars were...

Introduction: In arid and semi-arid regions, drought stress as the main factor and salinity stress as a secondary factor reduces plant growth and yield. Water limitation can damage pigments and plastids, reduce chlorophyll a, b, rate and grain filling period. One of the important strategies for...

Introduction: Recently addition of cheap and available organic compounds to soils has attracted attention of many researchers. Mineral salts are an important plant stress factor, having adverse impacts on urban trees and road verges where salts are used for de-icing. Material and methods: Here we...

Background and objectives: Long term exposure of tissue culture plants to unusual environmental conditions during in vitro production (e.g. high relative humidity, low CO₂ concentration during the photoperiod, high ethylene concentration and restricted air movement) induce poor development of...

Knowledge of the pollination system and the amount of self-Incompatibility is the first step for choosing appropriate breeding method. This study was conducted to investigate the amount of self-incompatibility and selfing in 25 genotypes of cocksfoot Dactylis glomerata, a perennial forage grass,...

Savory (Satureja khuzistanica) is one of the nine endemic species which have phenolic compounds such as carvacrole and thymol in its essential oil and rosmarinic and other phenolic acids in its extract, has strong antioxidant and antimicrobial properties and remarkable effects on several diseases....

Background & Objective: The aim of this study was to investigate the effect of biochar obtained from pruning wastes of pomegranate trees comparing with vermicompost Oenothera biennis under drought stress. Materials & Methods: Treatments were different levels of organic modifier application...

Purple (Cercis siliquastrum L.) is one of the most important species in landscaping and afforestation. Due to both ecological and economical values, knowledge on the water needs and resistance of purple to different levels of drought stress is essential. Therefore, an experiment in a completely...

This study was conducted in greenhouse condition to investigate the growth, morphological and physiological changes and some antioxidant enzyme activities of one-year-old seedlings of Alnus subcordata C. A. Mey. inoculated with Rhizophagus irregularis mycorrhizal fungi under water deficit stress in ...
