The Effects of Different Strength of MS Media on In Vitro Propagation and Rooting of Spathiphyllum

ANADOLU JOURNAL OF AGRICULTURAL SCIENCES (2022)

Dicle Dönmez Mansur HAKAN EROL Belgin Biçen Özhan Şimşek Yıldız Aka Kaçar

The Spathiphyllum, is an indoor ornamental plant belonging to the Araceae family. Spathiphyllum genus, which has 36 species in nature, is a very strong growing and easy to care for an indoor plant. Vegetative propagation of spathiphyllum is known to be difficult. For this reason, current production does not meet the demand sufficiently. Today, plant tissue culture methods are used in addition to classical production methods to meet the increasing demand for spathiphyllum. In the present study, we aimed to detect the effects of different strengths (full, ½, and ¼) of MS media on micropropagation and rooting of spathiphyllum. Shoot tips of spathiphyllum ‘chico’ variety were cultured in different strengths of MS media containing 1 mg L-1 BAP for micropropagation. Plantlets obtained from micropropagation were transferred to different strengths of MS media containing 1 mg L-1 IBA for rooting. Plantlets in magenta boxes were removed and replaced in a controlled greenhouse. The best strength of medium was detected as the full MS in all parameters in vitro propagation. The rooting rate was determined 100% for each medium. However, there are significant differences among the media in view of the number of roots, length of roots.

Genetic diversity within Turkish watermelon [Citrullus lanatus (Thunb.)Matsumura & Nakai] accessions revealed by SSR and SRAP markers

TURKISH JOURNAL OF AGRICULTURE AND FORESTRY (2016)

I. Solmaz Yıldız Aka Kaçar Nebahat Sarı Özhan Şimşek

The genetic diversity of Turkish watermelon genotypes selected from the watermelon genetic resource collection was evaluated by simple sequence repeat (SSR) and sequence-related amplified polymorphism (SRAP) markers. Most of the accessions were collected from various geographical regions of Turkey. Different Citrullus species, wild relatives, foreign landraces, open pollinated (OP), and commercial hybrid cultivars were also assessed for genetic relatedness. Fourteen SSR primers and 31 SRAP primer combinations were used in the experiment. Both SSR markers (100%) and SRAP markers (97.3%) generated high polymorphisms. Based on the SSR and SRAP data, the genetic similarity coefficients were calculated, and dendrograms were constructed using the unweighted pair-group method with arithmetic average (UPGMA). Cluster and principle coordinate analyses indicated that Citrullus lanatus var. Lanatus subspecies genotypes collected from the different regions of Turkey were closely genetically related. Overall, our results displayed low genetic variability within the Turkish watermelon germplasm in contrast with their high morphological diversity.

The effects of mechanical pruning on fruit yield and quality in 'Star Ruby' grapefruit.

Journal of Food Agriculture & Environment (2010)

Bilge Yıldırım Turgut Yeşiloğlu Meral İncesu Müge Kamiloğlu Faruk Özgüven

Increasing the high-quality yield of a cultivated fruit species is an important method for improving its ability to compete in world markets. A high fruit yield and an increase in the proportion of marketable fruit will aid in obtaining the market objectives for the species. To this end, pruning is a very important horticultural practice. Mechanical pruning has numerous advantages over classical pruning, such as enabling control over the tree size and providing mechanization in large and dense orchards that make hand pruning applications difficult and expensive. Mechanical pruning is used widely in developed countries for many horticultural crops including citrus. In Turkey, established citrus orchards generally have dense foliage and planting, making pest and disease management very difficult. It is necessary to improve orchard management and to introduce new technologies to production areas. Thus, the introduction of mechanical pruning into Turkish citrus orchards may have the potential to improve production. In this study, our aim was to determine the effects of mechanical pruning applications on the 'Star Ruby' grapefruit, the most commonly grown grapefruit variety in Turkey. Our pruning treatments included the following: 1) hedging, 2) topping and 3) hedging and topping. The study was carried out with thirteen-year-old Star Ruby grapefruit trees that were budded onto local sour orange (Citrus aurantium L.) rootstock. The trees were planted using semi-dense spacing (8 m x 4 m) in orchards established in Adana between 2004 and 2006. The orchard was then mechanically pruned each year. Our results indicate that the highest yield was obtained from the topping-hedging treatment, while the lowest yield was obtained from the topping treatment. Mechanical pruning, especially the topping treatment, increased the fruit size as compared to the control. Taken together, our results demonstrate that mechanical pruning is a potential option for grapefruit planted in semi-dense orchards. The small decrease in yield due to the mechanical pruning may have been caused by the repeated application over three years.

In Vitro Culture of Turkish Origanum sipyleum L.

American Journal of Plant Biology (2017)

Başar Sevindik Tolga İzgü Özhan Şimşek Mehmet Tütüncü Pembe Çürük

Origanum sipyleum L. is a species that is endemic to Turkey with known medicinal and aromatic properties and with a long historical use in Turkish folk medicine. Micropropagation serves as one possible method to clone and protect O. sipyleum . In this study, nodes, which served as the explants, were cultured on Murashige and Skoog (MS) basal medium supplemented with different concentrations of BA (0.1, 0.5, 1.0 mgL -1 ) and GA 3 (0.1, 0.2 mgL -1 ). Shoots were transferred to MS medium containing different concentrations of IBA (0, 0.5, 1, 1.5, 2, 2.5, 3 mgL -1 ) for root induction. Shoot regeneration, rooting, survival and acclimatization were possible. As many as 85% of nodes formed an average of 6 shoots/node on MS medium supplemented with 0.5 mgL -1 BA and 0.2 mgL -1 GA 3 . Rooting was most successful in 62.5% of shoots on MS medium with 1.5 or 2.5 mgL -1 IBA. Plantlets derived from all IBA combinations were transferred to autoclaved peat and perlite (1:1, v/v) and acclimatized in a greenhouse, with 79.1% survival. This protocol represents the first comprehensive in vitro regeneration protocol for endemic (Turkish) O. sipyleum .

Relationships among myrtle accessions from Turkey as revealed by fruit characteristics and RAPD

Sedat Serçe Kazım Gündüz Yıldız Aka Kaçar

Myrtle, Myrtus communis L., is one of the most important and widespread shrubs (maquis) throughout the Mediterranean region. Its fruits ripen during the period of mid-fall to early winter and are generally dark-colored although white-colored wild forms rarely exist. In Turkey, both forms are present in addition to a white and large-fruited type, cultivated in small orchards and marketed locally. We studied two sets of myrtle accessions from Hatay, Turkey. Set 1 consisted of two wild accessions, dark- and white-colored forms, and six cultivated selections, while Set 2 contained three open-pollinated individuals from each accession of Set 1. We evaluated fruit characteristics of including fruit weight, width, length, soluble solids, pH and acidity. The accessions considerably differed in all the traits tested except for soluble solids. We also examined genotypic variation of Sets 1 and 2 using 26 RAPD primers and analyzed the data by cluster and principle components analyses. The results revealed that although some of the half-sib families (e.g., 8 a, b and c) were grouped based on their maternal parents, no overall pattern was apparent. These results suggest that myrtle pollination appeared to be not restricted to the self-pollination and the cultivated types have a narrow genetic base.

Citrus production with its many varieties is of importance since it provides economically important products for Turkish exports.Sour orange is a rootstock commonly used for propagating the different scion varieties.Knowledge of the genetic diversity of the rootstock accessions would be useful in order to improve citrus breeding programs.We studied genetic relationships and diversity of 51 accessions of sour orange (Citrus aurantium) and their relatives using SSR (simple sequence repeat) and SRAP (sequence-related amplified polymorphism) molecular markers.Twenty-one SRAP primer combinations were tested on these accessions and relatives, producing 167 polymorphic fragments, with a mean of 8.0 and a mean polymorphism information content ©FUNPEC-RP www.funpecrp.com.
