An efficient protocol was established for rapid in vitro propagation of Stevia rebaudiana Bertoni, using explants from mature plants. The effect of 1/2MS, MS and B5 culture media, also 27 different combinations of auxins and cytokinins was studied on in vitro growth and development of Stevia rebaudiana Bertoni. The best culture medium for shoot and root formation was 1/2MS, producing 1.30 shoot...

microbial endophytes, which make one of the most important classes of soil microorganisms, induce genetic, physiological and ecological alterations in their host plant and thus increase its yield and enable its cultivation in saline or dry soils or in climates facing biotic and abiotic stresses. the endophyte fungus piriformospora indica exhibits a high effect in plant growth and increased resi...

Background: Thymus daenensis is on e of the endemic aromatic species in Iran that its essential oil is used in food and pharmaceutical industries. Objective: In this study, the effects of plant growth stages and distillation methods on essential oil content and thymol percentage of this species were evaluated. Methods: The aerial parts of Th. daenensis were collected in three stages of plan...

The measurement of plant features is a fundamental element of plant science research and related applications. The information related to plant features is especially useful for its applications in plant growth modelling and climate control in greenhouses or plant factory. Many methods have been applied in plant growth measurement. Traditional direct measurement methods are generally simple and...

Plant growth is influenced by a variety of abiotic and biotic factors. To survive a Complex and hostile environment, plants have evolved a series of inducible defense Mechanisms that enable them to activate appropriate defense responses upon Pathogen and abiotic stress factors attacking. Besides, rhizosphere bacteria also play a very important role in maintaining healthy plant growth process, s...

In the floriculture industry, the need for heat tolerant bedding plant cultivars is increasing because of the rising temperature around the world. A pot experiment was carried out to examine the impacts of four heat stress durations (0, 7, 14 and 21 days) on growth and ornamental traits to determine the relative heat tolerance of four cultivars of calendula (Calendula officinalis). Growth and d...

     Due to the environmental problems caused by the accumulation of significant amounts of waste from peanut cultivation, it seems necessary to provide a solution for the reuse of this organic waste. Therefore, this experiment was conducted to investigate the possibility of using compost of peanut shells in potting Begonia rex. This research was based on randomized complete block desi...

The efforts were made to study the impact of vermicomposted and composted farmyard manure (FYM) along with some combination of NPK fertilizers, on field crop of garlic (Allium stivum L.). A total of six experimental plots were prepared: T1 (recommended doze of NPK), T2 (vermicompost @ 15t/ha), T3 (20 t/ha vermicompost), T4 (15t/ha vermicompost + 50 % NPK), T5 (15t/ha farmyard manure), and T6 (f...
