گیلاس وحشی یکی از پهن برگان بومی سریع الرشد در جنگلهای هیرکانی می باشد که می تواند چوب باارزشی تولید کند. بذر گیلاس دارای خواب عمیقی است و تنوع زیادی در روشهای شکستن خواب بذر آن وجود دارد. با توجه به اهمیت گیلاس وحشی، این مطالعه به منظور غلبه بر خواب و جوانه زنی بذر آن انجام شد. برای این مقصود، بذر لازم از منطقه علی آباد کتول واقع در جنگلهای استان گلستان جمع آوری شد. سپس برای شکستن خواب بذر لای...
Phenology, as one of the most important subjects of ecology, is the study of periodic plant life cycle events and how these are influenced by variations in climate and ecological conditions. In this research, phonological observations of 5 species (Prunus dulcis, Prunus avium, Prunus armeniaca, Pyrus communis, Prunus domestica) were studied in Iranian orchard of National Botanical Garden of Ira...
Nature of Work: Many species of Prunus are notoriously intolerant of poor drainage. In some cases, inundation of the root system for only a few days can be sufficient to kill certain of these plants (1). Research conducted on commercial fruit trees, however, has shown there to be considerable variation in flood tolerance among different species and hybrids of prunus (3). For example, comparison...
Cherry laurel (Laurocerasus officinalis Roemer Syn: Prunus laurocerasus L.) is a perennial wild fruit plant that is widely distributed in and around South-Eastern Black Sea, Marmara Sea, the Caspian Sea in the North and the East. However, breeding success of cherry laurel depends on early harvest, transient differences in taste, fruit color and flavor due to large number of biotic and abiotic s...
The sequence of events which occurs during the ripening of the Passe-Crassane pear fruit have been previously studied. In this work, we have investigated the ripening of another climacteric fruit (Pyrus malus L. cv Golden Delicious) and of a nonclimacteric fruit (Prunus avium L. cv Bigarreau Napoléon). We show that both climacteric fruits exhibit the same preclimacteric sequence of events. Diff...
Prunus (Rosaceae) includes many commercially important fruit crop species that exhibit self-incompatibility (SI), including sweet cherry (P. avium L.), Japanese apricot mume Sieb. et Zucc.), plum salicina Lindl.), armeniaca and almond dulcis [Mill.] D. A. Webb.). These S-ribonuclease-based gametophytic SI, which prevents self-pollen tube growth in the pistil. The successful production of self-f...
This study aimed to identify fungal species associated with trunk diseases of sweet cherries (Prunus avium) in several commercial cherry orchards Beijing, Guizhou and Shandong provinces, China. In total, eighteen strains that fitted well into the concept Diaporthe were isolated. Based on both morphological multi-locus phylogenetic analyses internal transcribed spacer region (ITS), beta-tubulin ...
Prunus necrotic ringspot virus (PNRSV) causes yield loss in most cultivated stone fruits, including sweet cherry. Using a small RNA deep-sequencing approach combined with end-genome sequence cloning, we identified the complete genomes of all three PNRSV strands from PNRSV-infected sweet cherry trees and compared them with those of two previously reported isolates.
We conducted SSR analyses of 59 accessions, including 29 traditional plum (Prunus domestica), 24 sweet cherry (Prunus avium), and 1 sour cherry (Prunus cerasus) selected from East Anatolian gene sources and 3 plum and 2 cherry reference accessions for molecular characterization and investigation of genetic relationships. Eight SSR loci [1 developed from the apricot (UDAp-404), 4 from the peach ...
گیلاس یکی از مهم ترین میوه های مناطق معتدله در دنیا است. اکثر ارقام گیلاس به دلیل خود ناسازگاری، همواره مشکلاتی را از نظر تلقیح و میوه دهی به همراه داشته اند، لذا برای تولید میوه تجارتی نیاز به گرده دهنده مناسب و سازگار دارند. در این آزمایش گیلاس رقم قرمز رضاییه به عنوان گرده گیرنده با دانه گرده ارقام زرد دانشکده، پروتیوا، صورتی لواسان، حاج یوسفی، مشکین شهر و همچنین قرمز رضاییه گرده افشانی شد. ...
