Read More Background and Objectives Mulberry (Morus spp.) is a tree of the family of Moraceae. There are 24 species of Morus and one subspecies, with 100 known varieties. The various methods used in classification of Morus were mainly based on the conventional systematic studies and agronomic characters. Despite the widespread genetic diversity in Iranian mulberry tree, so far, the identification of these trees has not been selection, introduction and cultivation. In order to identify mulberry trees during 1387-1392, they were collected from different provinces (Tehran, Mazandaran, Kurdistan, Markazi, Khuzestan, Fars, West Azarbaijan, Isfahan, Hamedan, Khorasan, South Khorasan, Semnan, Ardabil, Kohgiluyeh and Boyer-Ahmad, East Azerbaijan) according to the IPGRI (International Institute for genetic reserves). The aim of this study was evaluation of genetic diversity and mulberry clustering genotypes, on the basis and quantitative characteristics and to determine the genetic distance between them. Material and Methods Mulberry trees are widely distributed in Iran. After reviewing the population of mulberry according to descriptor of IGPRI throughout the country, 118 specimens of mulberry from genotypes were selected and they were evaluated for their morphological characteristics. Some of these characters are quantitative and some others were measured and recorded based on coding UPOV. After collecting the data, descriptive statistics were extracted and analyzed. With the assumption of variance analysis distinguished genotypes into treatment and regions within each area as replication, design used nested. Mean comparison of quantitative traits LSD. Results The result of ANOVA showed average comparison of genotypes investigated difference was significant for all studied characteristics: the leaf margin, petiole length, flower diameter, which represent the coefficients of variation that were higher diversity among genotypes investigated. Therefore, there is the possibility of selecting genotypes for different values of an attribute. The characteristics that have high coefficients of variation are more diverse than the character coefficient with low variations. Discussions Analysis of simple correlation coefficients showed a significant positive correlation during the harvest time of fruit ripening r=0.82, the shape of inflorescence at the time of fruit ripening r=0.71, shape of inflorescence at the time of fruit ripening r=0.71 at 1% level. Brix with the shape by time of fruit ripening r=0.60 Brix of fruit shape r=0.28 fresh weight at the time of ripening r=0.81, significant positive correlations were calculated at 5% level. The results of mulberries ripen over an extended period of time unlike many other fruits. Using cluster analysis to the “Ward” based on morphological characterization at a distance of 15; genotypes were divided in three main groups. In order to determine the most important morphological characters to differentiate among the population of principal component analysis was used (PCA).The first components to 0.65 percent of total respectively. Overall, the results showed that great morphological variation among the plants population.

Read More Background and objectives Kiwifruit is a good source of natural antioxidant substances, in particular vitamin C. The studies on kiwifruit post harvest handling and storability would be helpful in marketability of high quality fruits and indeed it would be beneficial to our country’s economy. In order to examine the effects of summer pruning combined with calcium chloride spray and duration of storage on some quality features of kiwifruit, the present research was undertaken as a complete block design in factorial arrangement with four replications. Materials and methods The project was conducted during 2008-9 in a commercial orchard in Chalos, Iran. The CaCl2 was applied in four concentrations (0, 0.5, 1.0 and 1.5 %) and pruning was carried out in four levels including no pruning, leaving 2, 4, 8 leaves after the last fruit. Storage period included four levels between two to six months. Result It was found that, summer pruning could increase calcium content of pulp. The total soluble solids decreased by pruning treatments but no significant changes were recorded for other quantitative traits. Calcium chloride applications significantly enhanced calcium content of pulp section (p<0.001). Furthermore, the interaction of calcium chloride and time may significantly influence firmness, vitamin C content, pH, total acidity and total soluble solids. Maximum total acidity (1.118 g/100 ml), vitamin C content (60.111 mg/100 ml) was observed following spraying 1% CaCl2. Also, the lowest pH (3.445) and total soluble solids (12.7%) and maximum firmness (1.475) were recorded following application of 1.5% CaCl2, six months after storage. Discussions The results showed that the treatments had a significant effect on some traits and summer pruning improves fruit calcium's. Absolute increasing on fruit calcium density means sprayed calcium can penetrate in fruit epiderm and it can be because of weakness in cell membrane during development that can simplify calcium penetration. Also, summer pruning can increase fruit quality and improving antioxidant system and vitamin C by effect on light and air circulate in tree canopy and can increase calcium density in fruit texture by enhancing transpiration in fruits, because cutting the end part of developing shoots make reduction in competition between element absorption especially calcium element and make it flowed to set fruit.
