objective: in order to study the effect of drought stress, salicylic acid (sa) and jasmonic acid (ja) foliar application on hill reaction and photosynthetic pigments. methods:experiment was done as factorial on the basis of completely randomized design in 4 replications. irrigation in 3 levels (fc, fc and fc), salicylic acid in 2 levels (0 and 0.5 mm) and jasmonic acid in 2 levels (0 and 50...
Cucumber is one of the most important vegetable and summer crops economically and is the fourth most cultivated plant in the world after tomatoes and potatoes. In this study, the effect of plant inducers including salicylic acid and jasmonic acid on the viral disease of greenhouse cucumber with Cucumber mosaic virus (CMV) and also the expression of defense genes was investigated. Treatments inc...

In order to study the effect of seed priming with salicylic acid (SA) and jasmonic acid (JA) on emergence and early growth of pumpkin (Cucurbita pepo L.) seedlings under drought stress condition, a factorial experiment based on randomized complete block design (RCBD) with four replications was conducted at the greenhouse of Malayer university. Experimental treatments were seed priming with sal...
background & aim: sweet basil (ocimum basilicum), a plant that is extensively cultivated in some countries, is used to enhance the flavour of salads, sauces, pasta, confectioneries and other products as both a fresh and dried herb. the effect of foliar application of jasmonic acid and reduced irrigation on essential oil yield and chemical components of two iranian landrace of basil (ocimum ...
Jasmonic acid is a plant hormone that can be produced by the fungus Lasiodiplodia theobromae via submerged fermentation. From a biotechnological perspective jasmonic acid is a valuable feedstock as its derivatives serve as important ingredients in different cosmetic products and in the future it may be used for pharmaceutical applications. The objective of this work was to improve the productio...
An experiment was conducted to investigate the effects of jasmonic and humic acids on some seed germination characteristics of Roselle under the salt stress condition in a factorial experiment, adopting a completely randomized design with three replications. Treatments included four different levels of salinity stresses: 0, 70, 140 and 210 mM; four levels of Jasmonic Acid: 0, 50, 150 and 200 mM...
Background: Safflower (Carthamus tinctorius L.), is an important medicinal plant of Asteraceae family, which is a rich source of pharmaceutically active compounds including phenols, flavonoids and fatty acids. In traditional medicine this plant has been used as an herbal medicine to treat various diseases. Objective: The aim of this study was to evaluate the role of jasmonic acid to protect saf...
Two independent parameters, epicotyl height (cm) and number of induced buds were studied on Pinus pinaster explants to analyse the effects of three phytohormones (6-benzylaminopurine, jasmonic acid, ethylene) which were combined or not in 11 different treatments. Epicotyle length diminished significantly in relation to the control medium (medium without exogen phytohormones) in presence of jasm...
