rice is the world's most important food crop. to decrease the damage of rice pests, development of insect pest management strategies in rice is necessary. biennial results for determination of a suitable method to control striped stem borer in rice showed that integration of two methods of control (biological and mechanical) is a feasible effort to reduce stem borer infestation. to assure...
agriculture sector in iran and some other countries of the world has a vital role in national development. animal husbandry sub-sector needed meat of the society, creating related jobs and producing raw materials of some industries. acquiring scientific and sound information of the current situation of regions are important and imitative step in improvement program planning. the purpose of this...
Harvest time, in olive, is an important key to achieve high quality and quantity of oil with a desired and balanced fatty acid (high oleic acid and low palmitic and linoleic acid) composition. Appropriate harvesting time varies in different locations depending on climatic and agronomic situations and identifying the right time for harvesting may bring about a high quality oil. Thus, the current...
Study of combining ability and heterosis were conducted on 12 F1 hybrids along with seven rice genotypes (three cytoplasmic male sterile lines and four restorer varieties) to know the pattern of inheritance of some morphological traits for selecting superior genotypes. The experiment was carried out according to line x tester mating design, in Sari Agricultural Sciences and Natural Resources Un...
Five rice genotypes (Hassani, Dailamani, Shastak-mohammadi, Sange-tarom and Daei-shastak) and their 10 hybrids obtained through half a diallel set were evaluated for combining ability and gene effects studies of early maturity and yield traits. Single seedlings of each entries were transplanted at 20×20 cm spacing in 2×4 plots using a randomized block design with three replications during 2004...
The Ghezel Ozan basin in an area of 50000 KM2 is in the northwest of Iran. Recognition of variables like captivity and deviation of rivers, erosion and compact surfaces, the affects of old lakes by the reflected affects on 1:50000 scaled topographic maps of the region, are some of the points which is tried to find out the changes of Quaternary of the basin. Although Ghezel Ozan basin is ended t...
Olive tree is one of the most important oleaginous crops in the world, and known for having large genetic variability. Application of molecular markers is a suitable tool to investigate the genetic pool in crops. Therefore, in the current study 29 olive cultivars were tested by ten primers constituted by inter simple sequence repeats (ISSR). Plant materials were obtained from the collection of ...
Present study aimed to assess the relationship between grain yield and its components in 116 rice genotypes in F₂ generations obtained from crosses between Tarom-Jelodar and 229R cultivars. Correlation analysis showed that the number of panicle per plant (0.758), the number of filled grains per panicle (0.604), the 100 grains weight (0.401) and grain width (0.234) had significant positive r...
TThis study was undertaken with the objective to determine the association between grain yield and its components and identifying traits have the greatest effects on grain yield of 45 mutant lines from tarom-mahaliin a randomized complete block design with three replications. Analysis of variance showed significant differences among genotypes for all traits. Mean comparison showed that line 2...
background: aflatoxins are toxic fungal metabolites enable to contaminate a wide range of natural substrates. this contamination can be host-specific for different plant species. in this study, the ability of a toxigenic aspergillus parasiticus to produce various aflatoxins on major iranian cereals was evaluated with special focus on plant susceptibility to toxin production at cultivar level. m...
