Application of green walls still has not attracted interest among the contractors and people, and this can be due to poor growing performance of the plants on these systems. This study investigated the effect of four growing media types (30% cocopeat + 65% perlite + 5% vermicompost, 30% soil + 65% perlite + 5% vermicompost, 30% mushroom compost + 65% perlite + 5% vermicompost and regular soil a...
Effects of water stress on fruit fresh and dry weights were investigated in peach trees, Prunus persica (L.) Batsch., with varying crop loads: light, moderate and heavy. In well-watered controls, tree water status was independent of crop load. In trees receiving reduced irrigation, the degree of water stress increased with increasing crop load. Water stress induced fruit fresh weight reductions...
satureja rechingeri, belonging to the family lamiaceae, has been recently used in the pharmaceutical industry due to its high level of carvacrol in the essential oil. the domestication and breeding of suitable s. rechingeri variety has been started since few years ago in iran. the initial screening of natural populations, grown in the same environment, was performed and 58 talent clones were se...
Background & Aim: Deanaie thyme (Thymus daenensis Celak.), a member of the Lamiaceae family. Thymus in one of the most important medicinal and aromatic plants that was used in pharmaceutical, food, cosmetics hygienic industries in most of developed countries. Recent studies have showed that thyme have strong antibacterial, antifungal, spasmolytic and antioxidant acti...
Background and objectives: The application of growth-facilitator materials to improve germination, early establishment, and plants growth can increase the success of rangeland improvement, planting, and pasture construction projects. In addition, growth facilitators can improve the quantity and quality of vegetation cover and production in dry-farming lands by increasing the success of cultivat...
Silicon (Si) is one of the beneficial elements for plants, which improves quantity and quality of yield, decreases evaporation and transpiration and enhances plant resistance to abiotic stresses. In order to evaluate the effect of Si and nano-silicon (N-Si) on growth, morphological and photosynthesis attributes of tomato, cultivar Falcato, an experiment was carried out in a hydroponic system, ...
For comparing the effects of two planting substrates on vegetative growth, flowering rate, fruit appearance and qualities, yield of four bell pepper (Capsicum annum L.) cultivars, a greenhouse 4×2 factorial experiment was done by using a completely randomized design with 4 replications. First factor was 80% cocopeat + 20% perlite and 80% mosspeat + 20% perlite and the second one was four bell p...
Seed priming is the most important technique for increasing the germination power. This study was conducted to investigate the effects of halopriming and hydropriming on improvement of seed germination in black locust (Robinia pseudoacacia L.) in a completely randomized design with 4 replications. Halopriming treatments of KNO3 with concentrations including (100, 250, 500, 750 mM) and hydropr...
Biochar reduces the bioavailability of a wide range of pollutants, especially heavy metals (HMs).To evaluate the effects of waste biochar of cutflower rose on growth characteristics and accumulation of lead (Pb) and cadmium (Cd) HMs of in lettuce, a factorial experiment, based on completely randomized design, with four replications was conducted. The amount of rose biochar at 3 levels (0, 5 and...
the autotetraploidy was achieved in basil using tip meristem treatment of seedlings with various concentrations of colchicine solution (0, 0.05, 0.1, 0.2, 0.5 and 0.75% (w/v) ph = 6). a significant increase in the essential oil content was observed in tetraploids as they carry the potential of productivity of 69 % more oil over the diploids. a field experiment was conducted to investigate the e...
