Mechanized harvesting of cucumbers offers significant advantages compared to manual labor as both shortages and costs of labor increase. However the efficient use of machines depends on breeding plants with longer peduncles, but the genetic and molecular basis of fruit peduncle development in cucumber is not well understood. In this study, F2 populations were developed from a cross between two ...
Drought is one of the main dangers for optimum production of wheat. Achieving optimal results in breeding programs require to make informed choices of parents based on general and specific combining ability.In order to study the genetic characteristics, general and specific combining abilities and gene actions under drought stress conditions, a half diallel cross including 9 varieties of wheat ...
Drought stress is a critical and inevitable phenomenon damages successful crop production in various intensity every year in different parts of the world during different times. This research was done to evaluate the effects of drought stress on some traits related to leaf (leaf weight, leaf area and chlorophyll content) root (root weight) and shoot (weight and length) further enzymatic antioxi...
Agropyron is one of the most resistant plants to biotic and abiotic stresses. It plays an important role in forage yield in rangelands. Genetic variability based on different markers is the important step in crop improvement. In order to evaluate the genetic variation of different Agropyron species based on morphological and chemical traits, this experiment was carried out in the Agriculture an...
most sweet cherry cultivars are as found as self-incompatible and therefore for commercial fruit production, compatible pollinizers are needed. controlled pollination and microscopic examination of pollen tube growth in the style are two classical methods for determination of compatible and incompatible pollen donor cultivars. this experiment was carried out to explore the compatibility of ‘zar...
ten gerbera cultivars (‘labinel’, ‘lilla’, ‘alp’, ‘alberino’, ‘bonnie’, ‘avemaria’, ‘mammut’, ‘lexus’, ‘‘terramixa ’ & ‘sarolta’) were evaluated for their growth, yield and quality characteristics under protected conditions during 2011. among the cultivars studied, there were highly significant variations observed for growth, yield and quality parameters. longest stalk length (60.3 cm) was ...
abstract an investigation was accomplished during 2007 and 2008 to test effect of hormonal treatment and cutting position on rooting of sebri , shekari and natanz cultivars of pear (pyrus pyrifolia.) the experimental design was a two way factorial in a completely randomized method and with pgr5 treatment (iba and iba with naa in four levels in the first year and four higher levels of iba in sec...
Agricultural robots were designed based on the characteristics of target crop. In this study, two varieties black pepper including Kaimunda and Panniyur 1 evaluated for physical parameters to design a robotic harvester. The main objective study was measure analyze properties regard, studies conducted spike, peduncle, berry, vine separately. results showed that average length diameter spikes Kar...
تجزیه ژنتیکی برخی صفات مورفولوژیک در گندم از طریق تجزیه میانگین نسلها در شرایط تنش و عدم تنش رطوبتی
Study of heritability, types of genes action and determination of effective breeding strategy to improve physiological and morphological traits especially under drought stress conditions are very important. For such purpose, an experiment was carried out using the generations of the crosses between two pure lines (Kavir × Roshan) under drought stress and non-stress conditions based on randomiz...
