background: biostimulants are amino acids and organic components, which can play main role in the plant growth and dry matter accumulation. objective: determine the influence of foliar application of active amino acids on quality and quantity yield of melissa officinalis l. methods: this study was conducted in a research farm at the institute of medicinal plants on the base of randomized comple...
The impact of a native, leaf-feeding chrysomelid beetle (Phaedon sp. nr. oviformis) on bittercress (Cardamine cordifolia: Cruciferae), was evaluated in an exclusion experiment. Multivariate statistical analysis showed a significant increase in plant performance in the rotenone exclusion compared to performance in the paired control treatment. Plant response to the reduction of herbivory was a c...
abstract to investigate the effects of paclobutrazol (pbz) on vegetative and reproductive growth of strawberry cv. selva a factorial experiment in a completely randomized design with three replications was carried out in greenhouse of agriculture college, isfahan university of technology. pbz was applied in two methods, drench and foliar spray, at 0, 0.5, 1, 1.5 and 2 mg active ingredient per p...
a field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (hibiscus sabdariffa l.) in 2014/15 cropping season at wondo genet agricultural research center experimental site (at wondo genet station). two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, wg-hi...

A major component in a crop growth model is leaf area development, which has a major influence on photosynthesis and transpiration. The knowledge about the leaf area development of wheat especially in high temperature environments is incomplete. The aim of this study was to quantify leaf production and senescence of 15 spring wheat cultivars. Field experiments were conducted at the research far...
The rice plant need the silicon element more than other nutrition elements, but its importance has not been clearly known. In order to study of silicon effect on the growth and yield of rice (Tarom Hashemi variety), an experiment was carried out in pot and field conditions with three replicates in the greenhouse and in the field of Rice Research Institute of Iran (Amol) in 2009 and 2010. Three...
A generation mean analysis was conducted to study genetic of yield and yield related traits of bread wheat in drought stress condition. In this research F1, F2, BC1 and BC2 generations were developed created using Kavir and Roushan as parents. The generations and parents were evaluated in a randomized complete block design with three replications and the traits including yield, flag leaf area, ...
