Morus genus includes more than 20 species, some of which are commercially important mulberries with different fruit color and shape. Even though the trees of those species are propagated by rooting of cuttings in practice, mulberry seeds are of importance for breeding studies and rootstock seedling propagation. For that reason, this study was conducted to improve the seed performance of four mulberry species by different pre-sowing treatments including; 3% KNO3, GA3 at 500 ppm, organic priming with herbal tea brewed from marigold flowers petals and hydro priming. Results of the parameters of emergence characteristics and seedling vigor were evaluated. According to the results that varied between different species and pre-treatments, since emergence percentage and time, and seedling vigor were improved by the treatments, it was concluded that pre-sowing applications, especially GA3 and hydro priming, were beneficial in improving the seed performance of mulberry species included in the study.
The objective of this study was to evaluate seed characteristics of sponge gourd, to establish a core collection of sponge gourd with the germplasm collected throughout the Hatay region. A mini-core collection was assessed for morphological performance and some seed traits. Substantial variations of seed characteristics: seed length, seed width, seed thickness (mm), seed index (length/width), seed size (length × width, mm 2 ), seed colour, seedcoat surface, seed shape, seed wing, and 100-seed weight were investigated. Seed length, width and thickness were varied as 15.12-8.97 mm, 9.71-6.25 mm and 2.86-2.16 mm respectively. The seed sizes were determined from small (31 DÖ 06) to big (31 DE 04). Seed colours were ranged from black to white, even a brown colour like 07 MA 01. A hundred seed weights were observed as 16.43 g (31 AL 02) and 7.41 (31 DÖ 06). The results of dendrogram indicated that seed traits of the sponge gourd genotypes were separating in five groups. This collection of sponge gourds will be useful for the gene pools and a wide range of phenotypic variations to provide a good source of diversity for developing of sponge gourd cultivars in breeding programs.
The aim of this study is to determine some fruit characteristics of 19 different lines hybridized by previous regular studies. These lines were examined in order to determine the differences among volatile components and reveal the differences in comparison with the parents. Plant height (cm), fruit weight (g), fruit width (mm), fruit length (mm), fruit flesh thickness (mm), pungency, immature fruit color and mature fruit color were determined of parents and F4 lines. As a result, a wide range of variations were determined between lines and parents in terms of all parameters apart from pungency. Especially in terms of volatile components, it has been found that some active substances are found only in the father and white genotype (Fenchol, spathulenol and geranyl acetate), some of them only in the mother and orange genotype (α-terpineol, dihexyl azelate and 2-hexadecanol). It was concluded that volatile compounds of the species can be used as a marker for breeding studies.
Seeds of the tree tomato (Solanum betaceum Cav.) were treated with allelopathic plant extracts: ferula gum (FER, 0.2 g gum L-1, 25°C, 24 h), lantana petal extract (LAN, 4 g dried petal L-1, 25°C, 24 h) and marigold petal extract (TAG, 4 g dried petal L-1, 25°C, 24 h) along with an untreated control to determine the effect of these extracts on seedling emergence and performance. The pre-sowing influence of the allelopathic extracts (FER, LAN and TAG) on the emergence percentage (%), mean emergence time (days), emergence index, coefficient of velocity of emergence (%), seedling length (cm), seedling fresh weight (mg), seedling dry weight (mg), and stimulatory allelopathic index (%) was investigated in tree tomato seeds. The results revealed that pre-sowing treatment with the studied allelopathic plant extracts showed higher seedling emergence and performance. The greatest advantage of the pre-sowing treatment was observed in the TAG treatment. Allelopathic TAG treatment resulted in 15% higher seedling emergence rates, 3.3 d faster mean emergence time, 153 mg heavier seedling weights, and higher emergence index compared to untreated seeds. In addition, the effect of allelopathic FER and LAN treatments was better than the control.
Having wide range of genetic resources, Hatay is the largest sponge gourd producer of province of Turkey. This study was conducted to determine the status and morphological diversity of the livestock breeding with a field survey in the districts of Hatay Province. As a result of the survey, 34 genotypes were collected that thought to be morphologically different. When the distributions of genotypes were examined, the genotypes were selected from Arsuz (5 genotypes), Defne (7 genotypes), Samanda? (1 genotypes), Antakya (5 genotypes), D?rtyol (6 genotypes), Yaylada?? (4 genotypes), Alt?n?z? (4 genotypes), Payas (1 genotypes) and Erzin (1 genotypes). Two genotypes (?31 AN 03? and ?31 AL 04?) from which the seeds did not germinate were extracted from the morphological characterization studies. Thirty-two genotypes selected from Hatay with 3 genotypes obtained from Adana, South Korea, and China in total of 35 genotypes were compared in terms of 49 different morphological characteristics. Variations between the genotypes were not identified for the observations made on these 49 features regarding cotyledon color, stem shape, tendrils, leaf margin, growth habit, sex type and peduncle separation from fruit. As a result of analysis of basic components and cluster analysis based on morphological characterization features, genotypes were included in six different groups. However, the effect of the districts on which genotypes were collected on this grouping could not be determined.
