Characterization of genetic variability in a population is pertinent as genetic diversity within population and within species determines the extent of improvement achieved through crop improvement 8 methods. One hundred ninety six F recombinant inbred lines (RILs) of tef, developed by single-seed descent method from a cross between two tef varieties DZ-01-196 and DZ-01-2356, were evaluated to ...
Development of a reproducible, versatile and efficient in vitro plant regeneration system is highly warranted for Indian soybean varieties for their mass multiplication in view of their commercial significance. Accordingly a protocol for direct shoot organogenesis in soybean variety JS 335 has been developed. Using cotyledonary node explants significant organogenic responses, mean shoot number ...
To observe the comparative effects of poultry manure, household waste compost and fertilizers and their combinations on growth and yield of maize (Zea mays L.), this experiment was conducted in the crop field of the Department of Soil Science, University of Chittagong, Bangladesh during Rabi season in 2010-2011. There were ten treatments, one control and nine fertilizer combinations. In three s...
Background and aim: The genus Satureja L. (Lamiaceae) includes 12 species of annual and perennial herbaceous plant in Iran. Satureja species have economic and medicinal importance because of their high essential oil content. In addition, they are used as culinary herbs and in the food, perfume and cosmetic industries. The aim of this study was to inve...
This experiment was conducted to determine the effect of salinity and nitrogen on growth and yield of tomato and concentration and total uptake of some nutrients in different parts of plant in hydroponics culture. Nitrogen (N) was used at 0, 1.5 and 3% levels as NH4Cl and NH4H2PO4 and salinity consisted of 0, 30 and 60 mM as NaCl and CaCl2 (2:1 w/w). A completely randomized design experiment wa...
Nickel (Ni) is the most recently discovered essential element for higher plants. But there is limited information about the effect of this element on yield and nitrogen (N) metabolism of different plants. In this research, the interaction of Ni supplement and N source was studied on nitrate accumulation and growth of lettuce (Lactuca sativa L. cv. Baker) in solution culture. In a greenhouse exp...
in other to evaluation of morphological and phenological traits of 24 populations, from four species chamomile of the genus of anthemis, an experiment were carried out using randomized completely blocks design (rcbd) in three replications in alborz research station in karaj, iran during 2011-12. 13 traits including: length and width of canopy diameter, plant height, number of flower, shoot fres...
Selenium (Se) is a beneficial element for plant but at high concentrations, it is toxic and causes in plant growth retardation. There is limited information about the effects of Se on salinity-induced damages on wheat. Therefore this study was carried out to investigate interaction of salinity and Se on root and shoot dry matter yield, activity of GPX, and concentrations and uptake of selected ...
Evaluation of essential oil yield, morphological and phenological traits of seven populations of twoChamomilespecies )Matricaria aurea and M. recutita), were carried out using Randomized Completely Blocks Design (RCBD) in three replications in Alborz research station in Karaj, Iran during 2011-2012. Data were collected for 12 morphological and phenological traits. Analysis of variance showed si...
The superiority of hybrids has long been exploited in agriculture, and although many models explaining "heterosis" have been put forth, direct empirical support is limited. Particularly elusive have been cases of heterozygosity for single gene mutations causing heterosis under a genetic model known as overdominance. In tomato (Solanum lycopersicum), plants carrying mutations in SINGLE FLOWER TR...
