Lignin is a major component of the secondary cell walls of vascular plants, and an obstacle in the conversion of plant cell wall polysaccharides into biofuels. Erianthus spp. are large gramineous plants of interest as potential energy sources. However, lignocelluloses of Erianthus spp. have not been chemically characterized. In this study, we analysed lignins, related compounds, enzymatic sacch...
Background: Basil (Ocimum basilicum L.), a member of the Lamiaceae family, has traditionally been used as a medicinal plant in the treatment of headaches, coughs, diarrhea, constipation, warts, worms, and kidney malfunctions. Objective: To investigate the foliar application effects of bio-stimulators and bio-fertilizers on morphological and phytochemical traits of basil (Ocimum basilicum L.). ...
Nowadays, introduction of conversion technologies to solve environmental problems in accumulation of sugarcane bagasse, as an alternative to peat, in the ornamental plants industry seems necessary. For this purpose, in an experiment, the effects of substitution of sugarcane bagasse + cow manure vermicompost with peat in 60% peat + 30% vermiculite + 10% perlite medium were examined on growth and...
in order to investigate the effects of plant growth promoting bacteria on growth characteristic of wheat, an experiment was conducted at the research greenhouse, faculty of agriculture, ferdowsi university of mashhad, iran, in year 2009. a completely randomized design based on factorial arrangement (3×6) with three replications was used. the first factor consisted of three cultivars of wheat (c...
abstractbackground and objectives: satureja khuzestanica is valuable and endemic medicinal specie that growing widely in southwest parts of iran. this specie is rich of phenolic compound carvacrol, therefore have considerable biological activities. satureja khuzestanica is a new medicinal plant in iran, and little research has been done on. thus, the present study with the aim of evaluating the...
This study was conducted to evaluate the response of germination, seedling growth and antioxidant enzymes activity 15 chickpea cultivars to salinity at the University of South Korea Dankook a factorial experiment in a randomized complete block design with four replications. The treatments include chickpea cultivars and, salinity levels of water (water with electrical conductivity 0.7 dS/m as a ...
Leaf characteristics of mature 2, 3 and 4-year-old North American ginseng (Panax quinquefolius L.) leaves on fruiting and non-fruiting (NF) plants were studied. Leaflets of the 2-year-old plants had the lowest fresh and dry weight, area, volume and internal gas volume. Inflorescence removal in 3-year-old plants did not affect leaf characteristics or ginsenoside concentration but in 4-yearold pl...
To evaluate effect of different irrigation regimes and mycorrhizal fungi on the growth and yield of mungbean NM92 [Vigna radiata (L.) Wilczk], a field experiment was conducted in split plot arrangements using randomized complete block design (Irrigation after 50, 100, 150 and 200 mm evaporation from pan class A as main plots and mycorrhiza species, Glomus mosseae, G. intraradices and a non-inoc...
introduction major cultivated cotton regions of iran are located in dry and semiarid climates, therefore water deficiency or drought stress is inseparable part of cotton production systems in these regions. so identification and introduction of drought tolerant cotton genotypes is crucial. showed that water stress decreased plant growth rate, leaf area and finally photosynthesis in cotton. in a...
Plant growth regulators (PGRs) have an important role in callus induction and organogenesis of plant explants cultured in vitro conditions. Callus has a proper potential for plant regeneration through indirect organogenesis and embryogenesis as well suspension culture, genetic transformation and production of secondary metabolites. In current experiment, leaf explants of Petunia × hybrida F1 we...
