  The attitude of policymakers and designers of green space is increasing toward to native-ornamental species to plant in the urban space because of their adaptation and resistance against severe weather and ecological conditions which can result in cost minimization and long-term survival in green spaces. Hence, the current study was carried out in the west of Mazandaran Province on three wild and domestic species, including Cyclamen, Primula, and Viola. Morphological traits were the appearance of blossom, length and width of leaf, pedicel, petiolate, and flower. Homogeneity of variance was done by Levene test and two groups, including wild and domestic species, were also compared by independent t-test. Results showed that all measured traits were higher in the domestic species than in wild species except wild species of Viola which had higher length, width, and area than the domestic one. All domestic species showed longer flowering period than wild ones. Two species of domestic and wild Primula enable to be green after flowering period, but domestic Viola and wild Cyclamen disappeared after the period. Moreover, wild Viola and domestic Cyclamen survived after flowering finalization پرونده مقاله

  The cyclamen (Myrsinascea) as the flowers growing in some temperate regions, are of high ecological and botanical importance and endangered as well. Therefore, to provide an opportunity to identify and protect its species, Iranian native cyclamen was studied. Plants were collected (in winter and spring) from three northern provinces of Iran, i.e., Guilan, Mazandaran, and Golestan, and their morphological traits (14 quantitative and 10 qualitative traits) were assessed. Based on the analysis of variance, there were significant differences in some recorded traits, e.g., leaf number, flower number, flower color, and flower and leaf shape, which would allow selecting plants with more optimal traits. The cluster analysis divided the plants into three groups. Accordingly, the plants collected from the Shadan region in Golestan province and those collected from the Sinava and Shahsheshmeh regions in Chalus County, Mazandaran province differed from the plants collected from the other regions. The plants were collected from the Abpari and Lavij regions in Nur County, the Pasand region in Behshahr County, the Qarnabad region in Gorgan County, and the Deylaman region in Siahkal County were placed in the same group due to their similar morphology although they had been collected from three different provinces. The first group included the cyclamens of the Qarnabad region in Gorgan County, the Lavij region in Nur County, the Deylaman region in Siahkal County, the Pasand region in Behshahr County, and the Abpari region in Nur County. These plants had lowly toothed leaf margins, long petals, and few seeds. The second group included the cyclamens of the Shadan region in Kordkuy County. These plants had longer and heavier hypocotyls, larger and wider leaves, and smaller flowers. They showed the highest number of seeds, hypocotyl diameter, length, and weight, flower number, leaf length and width, leaf area, petiole and peduncle length, and peduncle diameter. The third group included the cyclamens of the Sinava and Shahsheshmeh regions in Chalus County. They had the highest petal width but the lowest peduncle diameter, leaf length, width, and area, flower and leaf number, and hypocotyl weight, length, and diameter. The cyclamens native to Iran are highly diverse in morphological traits and they need to be further investigated by cytogenetic, phytochemical, and molecular methods. پرونده مقاله

  3 - Pollen Germinability and Cross-Pollination Success in Persian Cyclamen (Cyclamen persicum Mill.)

  Low seed yield is a limiting factor for cross breeding and hybrid seed production in cyclamen. This study was performed to investigate pollen germination and its relation to cross-pollination success and fruit set in this plant. In order to achieve a high level of pollen germination, the effect of different concentrations of chemical compounds were examined on in vitro pollen germination of cyclamen in modified Brewbaker and Kwack medium, containing sucrose (10 and 20%), calcium nitrate (0, 200 and 300 mg l-1), and boric acid (0, 100 and 200mg l-1 ) at two pH levels (5.5 and 6.5). Maximum pollen germination was obtained in media containing higher concentration of calcium and boron regardless of sucrose concentration and pH level. Pollen germination percentage was genotype-dependent. Cross-pollination was performed among four different genotypes characterized by various pollen germination percentages. There was a direct correlation between cross-pollination success and pollen germination percentage. Genotypes with 30% higher pollen germination led to 10% increase in fruit set. پرونده مقاله

  سیکلامن یکی از گیاهانی است که جنبه صادراتی دارد و همچنین در صنعت داروسازی کاربرد دارد. از این رو افزایش تعداد گل دوام و ماندگاری گلهای شاخه بریده آن مورد اهمیت است. الکل در غلظت های کم بر این خواص تاثیر مثبت دارد. به همین جهت هدف از این پژوهش اثر تیمارهای الکلی ( اتانول &ndash; متانول ) بر تکوین مریستم زایشی تغییر در تعداد شاخه های گل و امکان به تأخیر انداختن پیری در گل های شاخه بریده سیکلامن می باشد از این رو گلدانهای حاوی قسمت های رویشی گیاه سیکلامن) (Cyclamen persicum Miller. که هنوز وارد مرحله زایشی نشده بودند از گلخانه پرورش سیکلامن در تهران تهیه شدند. سپس نمونه های شاهد سه روز در هفته به میزان ده سی سی آب مقطر به برگها اسپری شد و نمونه های تحت تیمار با همان روش تحت تأثیر تیمارهای الکلی اتانول و متانول با غلظت های و درصد قرار گرفتند. در این پژوهش غنچه های گل در سه مرحله تکوین برداشت شدند و با روش های متداول سلول &ndash; بافت شناسی مراحل تکوین مریستم زایشی تشکیل غنچه ها و اجزای گل مورد بررسی قرار گرفتند. نتایج حاصل از بررسی غنچه های هم سن و هم اندازه در نمونه های شاهد و تحت تیمار نشان داد که الکل ( اتانول &ndash; متانول ) مراحل تکوین بخش های مختلف اجزای گل را تسریع می کند. پرونده مقاله
