A glasshouse study was conducted to measure the effects of salinity and drought stresses on growth and chemical and biochemical composition of 4 onion cultivars. The cultivars were Dessex, Texas Early Grano (Texas), Dehydrator, and PX492. Salinity treatments included control, 45mM NaCl, 45mM NaCl + 5mM CaCl2 and drought treatments were control (maintaining soil moisture at field capacity) and...

Cadmium (Cd) is one of the main elements that cause heavy metal pollution, which important types environmental pollution. There a constant quest to reduce or eliminate effects Cd Plant growth-promoting rhizobacteria (PGPR) these possible solutions. PGPRs not only increase plant growth but also protect plants against organic and inorganic stresses. In this study, three different Pseudomonas stra...

A symbiotic relationship exists between the endophytic fungi of the genus Neotyphodium and many cool-season grasses. Endophytes can alter the growth as well as morphological and physiological characteristics of the host plant, thereby influencing the persistence and survival rate of infected plants. This study was conducted to evaluate the effects of endophyte on phenotypic characteristics of I...

The ontogeny of carrots (Daucus carota cv. 'Spartan Premium') grown under greenhouse conditions in pots of organic soil infected with Meloidogyne hapla was influenced detrimentally as early as 4 days after seeding, as determined through analysis of plant surface area, dry weight, fresh weight, net assimilation rate, relative growth rate, and leaf-area ratio. Only 58% of the diseased carrots wer...

In Iran, Acacia victoriae is not native to tree in Iran but it is used for important goals such as stabilize hills and the beautify landscape in the southern regions of the Iran, especially in the Khuzestan and Ilam provinces. Researches that include the development of native and non-native trees, which are compatible with the conditions of dusting areas in the western provinces of Iran, are ve...
