The mango (Mangifera indica L.) is native to South and Southeast Asia, from where it has been distributed worldwide to become one of the most cultivated fruits in the tropics. It is the national fruit of India. In India, harvest and sale of mangoes take place during March-May and the fruits have high economic value in India. Studies were first time conducted on mango fruits to observe the severity of fruit cracking incidence. The stone was exposed in case of longitudinal type cracking and never exposed in star type cracking. The longitudinal cracking was 3.8, 3.4 and 1.7 % and star type cracking was 0.3, 1.8 and 0.02 % during 2009, 2010 and 2011, respectively. The lesser pulp thickness and higher stone weight in fruit cracked samples may have responsible for fruit cracking. There was a close relationship between fruit cracking and 3 months average weather conditions. The maximum temperature had positive relation with total fruit cracking.  相似文献

Turkey is one of the most important Rose germplasm centers. About 25% of all rose species are native to Turkey. Flowers of some rose species, such as Rosa gallica and Rosa damascena, have been used for rose oil and rose water production in Anatolia for a long time. Fruits (rose hip) of some other species have economic value and are also used for medicinal purposes. In this paper, Rosa species found in Turkey are listed, their distribution within the provinces is listed, as well as their characteristics and uses.  相似文献

Salinity is one of the major abiotic stress factors for cultivated plants, limiting their growth and productivity in many areas of the world. This study aims to determine the ameliorative effects of humic acid (HA) and plant growth-promoting bacteria (PGPR) on amino acids, enzymes, minerals, organic acids and hormones in Hungarian vetch (Vicia pannonica) plants under salinity stress conditions. Salinity stress was established by adding 0, 10, 30 and 60 mM of sodium chloride (NaCl) to growing media. HA and PGPR treatments had positive ameliorative effects on the minerals, organic acids, hormones and enzyme activity of Hungarian vetch plants under salinity stress conditions. PGPR treatments showed better ameliorative effects than HA. This study suggests that PGPR treatments have the potential to be used as alleviator fertilizer in salinity stress conditions and may have ameliorated the deleterious effects of salt stress on Hungarian vetch plants.  相似文献

During 2003 and 2005, plant growth promoting effects of two Bacillus strains OSU-142 (N2-fixing) and M3 (N2-fixing and phosphate solubilizing) were tested alone or in combinations on organically grown primocane fruiting raspberry (cv. Heritage) plants in terms of yield, growth, nutrient composition of leaves and variation of soil nutrient element composition in the province of Erzurum, Turkey. The results showed that Bacillus M3 treatment stimulated plant growth and resulted in significant yield increase. Inoculation of raspberry plant roots and rhizosphere with M3 and/or OSU-142 + M3, significantly increased yield (33.9% and 74.9%), cane length (13.6% and 15.0%), number of cluster per cane (25.4% and 28.7%) and number of berries per cane (25.1% and 36.0%) compared with the control, respectively. In addition, N, P and Ca contents of raspberry leaves with OSU-142 + M3 treatment, and Fe and Mn contents of the leaves of raspberry with M3 and OSU-142 + M3 applications significantly improved under organic growing conditions. Bacterial applications also significantly effected soil total N, available P, K, Ca, Mg, Fe, Mn, Zn contents and pH. Available P contents in soil was determined to be increased from 1.55 kg P2O5/da at the beginning of the study to 2.83 kg P2O5/da by OSU-142, to 5.36 kg P2O5/da by M3 and to 4.71 kg P2O5/da by OSU-142 + M3 treatments. The results of this study suggest that Bacillus M3 alone or in combination with Bacillus OSU-142 have the potential to increase the yield, growth and nutrition of raspberry plant under organic growing conditions.  相似文献

The aim of the study is to determine the effect of different growth vigorous rootstocks on phenolic compounds in leaves of apple. For this purpose it was used the leaves of cultivar ‘Red Chief’ grafted on dwarf (M9), semi-dwarf (M26) and semi-vigorous (MM106) rootstocks. During mid-July, the leaf samples were taken from the middle part of annual shoots. Phenolics of the leaves were determined by HPLC analysis. While significant differences among the rootstocks for p-hydroxybenzoic acid, eriodictyol, ferulic acid and p-coumaric acid were detected, these differences were insignificant for gallic acid and quercetin. It was shown that semi-vigorous rootstocks (MM106) had higher phenolic contents in total than the other two dwarf rootstocks. In addition, apigenin-7-glucoside, chlorogenic acid, caffeic acid, rosmarinic acid, epicatechin, syringic acid, catechin, rutin, resveratrol, hesperidin, naringenin, luteolin, apigenin and acacetin could not to be detected. Data showed that there is the relationship between growth vigour and phenolic contents of apple leaves. Especially, p-hydroxy benzoic acid and p-coumaric acid contents were higher in semi-vigorous rootstock than in dwarf rootstock.  相似文献

Autochthonous apple varieties are still keeping their importance in Montenegro and they are valuable resources as human food and an important part of rural landscape. The aim of this study was to study and preserve morphological diversity of 30 autochthonous apple varieties in Montenegro between 2008 and 2010. We found a great variation on blooming period and maturation time among varieties and classified them as very early, early, mid and late for blooming and early, middle, late and very late for maturation. Fruit weight varied in wide range from 40.76 g to 206.74 g and ‘Krupnaja’, ‘Krstova?a’ and ‘Babova?a’ produced biggest fruits (191.83–206.74 g). Soluble solid content (SSC) varied between 11.0 to 16.1?% among varieties and ‘Borova?a’, ‘Aleksandrija’, ‘Krstova?a’, ‘Dapsi?anka’, ‘Bosnika’, ‘Rebra?a’ and ‘Babova?a’ had the highest SSC values imply that they can be commercially used in production of spirits, wine, concentrate and jam and also for drying. Based on 3-year average data for 25 properties, UPGMA (Unweighted Pair Group Method with Arithmetic Mean) dendrogram showed a high degree of variability among the studied varieties dividing them into 5 groups and 3 independent accessions.  相似文献

In vitro embryo culture enabled satisfactory germination of immature seeds produced in crosses from early ripening sweet cherry varieties (Prunus avium L.). Three varieties —‘Rita’, ‘Bigarreau Burlat’ and ‘Carmen’— were crossed with ‘Early Star’ as male parent. Germination rate was affected by the developmental stage of both fruit and embryo. Fruit ripening stage was a critical factor for culture infection rate that increased with maturity. In-ovule embryo culture on Murashige and Skoog medium without hormones improved the embryo size but did not increase the germination rate due to a further increase in infection rate. Ex-ovule embryo culture on Murashige and Skoog medium supplemented with BA 1 mg L?1, NAA 0.5 mg L?1, 20 g L?1sucrose, 10 g L?1 sorbitol and 6 g L?1agar during the stratification time increased embryo length. Germination was performed on Brooks and Hough medium at the 22?±?1?°C with 16/8 h light/dark photoperiod. The highest germination rate (75?%) was reached in embryos that were 3?4 mm in length, after 30-days stratification at 4?°C. Embryos in fruits at green-yellow stage that were 3?4 mm long were morpho-physiologically developed to produce bipolar seedlings, without combined application of embryo culture and micropropagation.  相似文献

Fruit skin color, total phenolics, total anthocyanins, soluble solids content, titratable acidity and total antioxidant capacity in fresh fruits of a number of local and well-known fig (Ficus carica L.) genotypes and cultivars grown in northeastern Turkey were determined. TEAC (Trolox equivalent antioxidant capacity) and FRAP (ferric reducing antioxidant power) assays were used to determine total antioxidant capacity. Fruit skin color of genotypes were found to be very diverse, i.e., light green, light purple, purple, dark purple and black. The content of total phenolics, soluble solids content (SSC) and titratable acidity greatly varied in the range from 24 to 237?mg of gallic acid equivalent per 100?g fresh weight, 18.60 to 26.30?% and 0.16 to 0.47?% in local genotypes and studied cultivars. In general, total antioxidant capacities determined by two methods expressed higher values in the local fig genotypes compared with the cultivars. The results suggested that genotype is the main factor that determines difference in the composition of bioactive compounds in figs and provide information on putative health benefits locally grown genotypes.  相似文献

Turkey is an important producer of cornelian cherries (Cornus mas L.), especially in northern Anatolia. Seed propagation and long-term human selection has given rise to a great diversity of trees. Twenty-six cornelian cherry genotypes (CC1–CC26) from the Coruh Valley in northern Anatolia were evaluated for genetic relationships by using Randomly Amplified Polymorphic DNA (RAPD) markers, based on 56 decamer random primers, seven of which showed reliable polymorphisms. These seven primers generated 80 markers, with 77 (96.25%) displaying polymorphisms. Cluster analysis of the cornelian cherry genotypes was performed based on data from polymorphic RAPD bands, by using Jaccard’s similarity coefficient and the Unweighted pair-group method with arithmetic average (UPGMA) clustering method. A similarity matrix showed that the highest genetic similarity (0.913) was between CC15 and CC16 and the least (0.129) was between CC4 and CC16. The cophenetic correlation coefficient between the similarity matrix and the cophenetic matrix of the dendrogram was relatively high (r = 0.87), supporting the validity of the dendrogram. Based on these results, RAPD analysis can be used for the characterization and grouping of cornelian cherry genotypes. Genetically divergent genotypes identified in this study may be useful for future breeding programs. This is the first study demonstrating that RAPD analyses can be used to differentiate and classify cornelian cherry genotypes.  相似文献
