study the effects of inoculation with two arbuscular mycorrhizal (am) fungi, gm (glomus mosseae t.h. nicolson & gerd.)gerd & trappe) and gi (glomus intraradices  n.c. schenck & g.s. sm.) on the  herb yield, essential oil (eo) content and nutrient acquisition of basil (ocimum basilicum l.) under drought stress conditions,the experiment conducted with 9 treatments and 4 replications. drought stre...

Nine monoterpenoids related to carvone and seven glucosides were isolated from the water-soluble portion of the methanolic extract of the caraway (fruit of Carum carvi L.), and their structures were clarified by spectral investigation. Among them, eight monoterpenoids and six glucosides were new.

abstract indian meal moth, plodia interpunctella hübner (pyralidae) is one of the most important stored-product insects that are controlled by fumigants. however, the use of plant essential oils and their constituents may have the advantage over conventional fumigants in terms of low mammalian toxicity and can be used as alternatives to conventional fumigants. therefore, in this research, repel...

Salinity is a major yield reducing factor in coastal as well as arid irrigated rice production systems. Salt induced abiotic stress is an acute problem, interrupting the metabolic processes of plants, resulting in reduced growth and productivity. Proline is an amino acid which increases in plants under abiotic stress. Salinity stress affects the metabolism of plants leading to severe crop damag...

Carum copticum L. is a medicinal plant of the Apiaceae family with medicinal properties. In this study, the effects of UV-B radiation on the photosynthetic pigments and essential oils as well as phenols and anthocyanin of the seedling and callus of C. copticum were investigated under in vitro conditions. For this purpose, the experiment was set up in a completely randomized design, with three r...

Background: Ferulago angulata is an important medicinal plant and endemic to Iran which is an endangered Plant. Objective: The aim of this study was to achieve an efficient method for propagation of this plant and evaluation of essential oil content and composition in habitat. Metthods: Essential oils were extracted by hydrodistillation using Clevenger-type apparatus and its composition was ...

Salinity stress is one of the main limiting factors for optimum agricultural productivity of safflower, Carthamus tinctorius L., in arid and semi-arid regions. It could leads to significant changes in plant biochemical, physiological, and growth traits. Salinity induced endogenous rise in jasmonic acid and its methyl esters (MeJA) has been reported. In the present study, effects of salinity str...

Effects of salt stress on germination, seedling growth and activity of antioxidant enzymes in leaves of six cultivars of canola (Brassica napus L.) were investigated on two F1 hybrids (Hyola401, Hyola330) and four open pollinated cultivars (Zarfam, Okapi, RGs003 and Sarigol). Seeds were germinated under various levels of salinity (0, 50, 100, 150 and 200 mM NaCl solutions). An increase in NaCl ...
