Leaf morphology, particularly in crop, is one of the most important agronomic traits because it influences the yield through the manipulation of photosynthetic capacity and transpiration. To understand the regulatory mechanism of leaf morphogenesis, an Oryza sativa dominant mutant, rolled and erect leaf 1 (rel1) has been characterized. This mutant has a predominant rolled leaf, increased leaf a...
Cultivated soils often are either deficient or possess toxic concentrations of one or more mineral elements that adversely affect emergence, growth, maturity, production potential, and/or nutritional quality of common bean (Phaseolus vulgaris L.). Our objective was to study the inheritance of resistance to soil Zn deficiency. The resistant `Matterhorn' was crossed with the susceptible 'T-39'. T...
This article analyzes the results of research conducted by scientists in study plants region. Taking into account laws distribution regions, dominant desert, hill, mountain and pasture regions South Uzbekistan are given an ecological phytocenotic description. In particular, expedition to distributed each region, experimental highlighted. According it, information on Latin name plants, status, a...
1. Different views exist as to what traits will lead to dominance when plants compete for light. One view is that taller plants with better relative positions in the canopy will exclude shorter plants because they intercept almost all light and thus can achieve a higher carbon gain. Alternatively, resource competition models predict that plants that are capable of positive net photosynthesis at...
the distribution and abundance of high aquatic plants in the gorganroud river was examined at five stations in four seasons (20 samples) over one year period during 2009-2010. we identified 21 species of aquatic plants from 21 genera, belonging to 9 families. these species were determined as 3 halophytic species (14.2%) and 18 high aquatic plants (85.7%).the highest species diversity was observ...

After first being ground-nesters and predators or scavengers, ants became arboreal with the rise of angiosperms and provided plants a biotic defense by foraging for prey on their foliage. Plants induce ants to patrol on their leaves through food rewards (e.g., extra-floral nectar and food bodies), while ants attend hemipterans for their honeydew. Most arboreal-nesting ants build their own nests...
a notable amount of medicinal plants grow in iran and local communities in different parts of the country have developed a deep knowledge of various uses of plants during their old history. several ethnobotanical studies have been conducted by the traditional medicine and material medica research center (tmrc) to investigate the use of medicinal plants by local people. some of these studies hav...
Around the world rangelands that have been degraded, such as historical desert grasslands now dominated by woody shrubs, are resistant to restoration efforts. The goal of this descriptive research was to examine the potential for black grama (Bouteloua eriopoda [Torr.] Torr.) recovery by remnant plants in a degraded area as a function of plant location across a landscape. Our objectives were 1)...
