nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
Pollination and fertilization of canola flowers are the main factors of canola seed production. In order to study the effects of insect pollinators on seed quantity and quality of three chosen cultivars of canola, namly, S.L.M., Okapi and Talaye, a split plot experiment in a complete randomized block design with four replications was carried out in Isfahan region. Main plots consisted of canola...
An experiment was conducted to investigate the heterosis in 12 F1 hybrids of durum wheat using agronomic and morphological traits. Parents were selected according to the estimated genetic distances based on the results of a two-year field experiment, which were then crossed to produce F1 hybrids. Twenty-three genotypes (including 11 parents and 12 hybrids) were evaluated using a randomized co...
abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...
analysis of genetic diversity in germplasm collections can facilitate reliable classification of accessions as well as identification of subsets of core accessions with possible utility for specific breeding purposes. to investigate the pattern of genetic variation in tall fescue (festuca arundinacea schreb) germplasm, a field experiment was accordingly conducted. seeds of 25 iranian, 11 hungar...
inter simple sequence repeat (issr) markers were used to assess the genetic diversity among 23 outcross and self pollinated populations of fennel collected from different geographical regions of iran and some european countries. the experiment was carried out to determine the effect of self-pollination on morphological traits and genetic diversity in the next generation. fifteen primers produce...
this study was conducted to evaluate genetic diversity of durum wheat cultivars using multivariate analyses on agronomic and morphological traits. thirty genotypes were planted in a randomized complete block design with three replications in 2003. agronomic and morphological characteristics including days to flowering, days to pollination, days to maturity, plant height, spike length, grain wei...
the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
مراتع حدود نیمی از خشکی های جهان را در بر دارند و پوشش گیاهی آن در نتیجه تأثیر متقابل محیط و موجودات زنده به وجود آمده است و به عنوان یک اکوسیستم طبیعی مدیریت می شوند. علاوه بر مراتع، راه ها در عصر حاضر نیز از اجزا مهم و زیرساخت های اصلی زندگی نوین و توسعه کشورها به شمار می روند. جاده ها ساخته دست بشر هستند و جوامع گیاهی کنار جاده تحت تأثیر ساخت و ساز قرار دارند. پوشش "رودرال" به مجموعه ای از پ...
The use of intra-varietal crossing is an important element to increase seed yield and improve a variety. aim the research was identify influence different options pollination sweet pepper on productivity other quantitative traits.
 It has been established, that re-pollination within variety in relation self-pollination causes reduction offspring period before fruit ripening by 3–7 days. Fo...
