This study was carried out on some domestic and foreign late blooming varieties and their genotypes obtained as a result of hybridization in the almond collection parcel of Harran University Faculty ...of Agriculture in Sanliurfa/Turkiye in the summer period of 2020. In the research, 5 different cultivars and 6 hybrids were examined in the orchard. In the study, 3 trees of each variety and 9 leaves from 2 directions of each tree were taken. North and South directions were taken into account when taking leaf samples. According to the findings, when the leaf characteristics were examined in general, the highest values in terms of leaf width, leaf length, petiole length and leaf area were found in ‘Type-7’ hybrids among cultivars and hybrids. As a result of stoma analysis on the lower surface of the leaves, the highest overall average (196.47 unitsmm-²) was determined in Type-3, while the lowest (127.10 units/mm²) was found in ‘Ferragnes’ variety. As a result of the analysis, when all the average values were taken into account, it was determined that the leaf area was 16.74 cm², the average stomata density was 153.51/mm² and the leaf area was 256975.74/leaf stomata. It is thought that the study will be descriptive for almond varieties and hybrids grown in the same ecology.
Bu araştırma, Güneydoğu Anadolu Bölgesi'nin kurak ve yarı-kurak ekolojik koşullarına sahip Şanlıurfa ilinde iki ayrı bahçede yetiştirilen hünnap (Ziziphus jujuba Mill.) genotiplerinin meyve, yaprak ...ve stoma özelliklerinin belirlenmesi amacıyla 2021 yılında yürütülmüştür. Araştırmada incelenen hünnap genotiplerinde meyve ağırlığı 2.78-20.28 g, meyve boyu 21.77-39.47 mm ve meyve eni 18.62-37.23 mm, yaprak alanı 3.11-7.01 cm2, yaprak eni 1.31-2.65 cm ve yaprak boyu ise 3.29-5.09 cm arasında belirlenmiştir. Hünnap genotiplerinde stoma sayıları 323.30 adet mm-2 (kültür hünnap)-333.31 adet mm-2 (yabani hünnap), ortalama stoma boyu ve eni değerleri ise sırasıyla 27.22 (yabani hünnap)-28.00 µm (kültür hünnap) ve 18.21 (yabani hünnap)-20.05 µm (kültür hünnap) arasında tespit edilmiştir. Elde edilen bu sonuçlara göre daha küçük yaprak alanına sahip olan yabani hünnap genotipinin stoma sayısı, stoma eni ve boyu değerlerinin istatistiksel olarak kültür hünnap genotipinden farklılık göstermediği belirlenmiştir. Bu bakımdan, birim alandaki stoma yoğunluğunun diğer türlere göre daha fazla olması nedeniyle, hünnap bitkisinin kurak ve yarı-kurak ekolojilerde ağaçlandırma çalışmalarında başarılı olarak kullanılabileceği düşünülmektedir.
This research was carried out in 2021 to determine the fruit, leaf and stomata characteristics of jujube (Ziziphus jujuba Mill.) genotypes grown in two separate orchards in Şanlıurfa province, which has arid and semi-arid ecological conditions in the Southeastern Anatolia Region. In the jujube genotypes examined in the study; fruit weight was 2.78-20.28 g, fruit length was 21.77-39.47 mm, fruit width was 18.62-37.23 mm, leaf area was 3.11-7.01 cm2, leaf width was 1.31-2.65 cm and leaf length was 3.29-5.09 cm. In the jujube genotypes, the number of stomata is 323.30 units mm-2 (culture jujube)-333.31 units mm-2 (wild jujube), mean stomatal length and width are 27.22 (wild jujube)-28.00 µm (culture jujube) and 18.21 (wild jujube)-20.05 µm (culture jujube). According to these results, it was determined that the number of stomata, stomatal width and length values of the wild jujube genotype, which has a smaller leaf area, did not differ statistically from the culture jujube genotype. In this respect, it is thought that the jujube plant can be used successfully in afforestation studies in arid and semi-arid ecologies, due to the fact that the stomatal density per unit area is higher than other species.
In this study, an in vitro propagation protocol of Poncirus trifoliata L. (Raf.) rootstock, which is one of the main rootstocks used in citrus, was created. Monocular node parts of the plant, which ...is the source of explant, were cultured in MS nutrient media containing BAP at dissmilar concentrations (0.5-1.0-2.0 mg/l). Afterward, it was observed that shoot appearance and tillering were achieved in the node explants cultured in MS nutrient medium comprising 1.0 mg/l BAP. The shoots were removed to a new culture in MS nutrient media containing NAA and IBA for rooting. While 30% rooting was achieved in the rooting medium, 62% of the rooted plantlets were acclimated to external conditions. 2 mg/l BAP and 2 mg/l silver nitrate (AgNO3) doses were supplied to the MS medium. The results of this study were obtained and a compound was found to the yellowing and leaf fall problem. As a result, in vitro propagation of Poncirus trifoliata, which is among the important citrus rootstocks, was tried, and its rooting ability was investigated in different nutrient media concentrations after shoots were obtained from different explants.
The aim of the research is to develop a suitable micropropagation protocol for the Poinsettia (Euphorbia pulcherrima Willd.) plant, which is used as an ornamental plant. In the sterilization step, ...mercuric chloride together with sodium hypochlorite is approved as the best option. Thus, contamination of explants is eliminated. At the shoot propagation stage, BA is absolutely necessary as all doses of BA increased shoot propagation compared to the control. The highest number of shoots per explant (2.62 shoots/explant) and the longest shoots (2.16 cm) were obtained from 1.0 mg.L-1 BA medium. The highest number of leaves (20.41 leaves/explant) was obtained from 2.0 mg.L-1 BA medium. Kinetin was also effective when adding different concentrations to the culture medium compared to the control. In general, BA is more effective than Kinetin in these parameters. Kinetin, on the other hand, performed much better than BA in terms of shoot number. On the other hand, the highest rooting percentage (58.2%) was obtained from the addition of 0.3 mg.L-1 NAA. The highest root number (5.10 roots/explant) was obtained by adding 0.1 mg.L-1 NAA. Good performance was found in the acclimatization phase with plantlets transferred to the soil with a high survival rate reaching 100%. Most of the plantlets started growing well. The plantlets grew well and did not show morphological abnormalities. In addition, a successful plant regeneration was achieved by adding 1.0 mg.L-1 BA and 0.5 mg.L-1 NAA on the callus produced in leaf disc explants and a very good organogenesis was determined in terms of roots and shoots.
In this study, the regeneration shoot tip and nodal explants grown in vitro conditions of ‘Garnem’ hybrid rootstock were investigated, the effect of different phytohormone and concentrations on ...obtaining adventitious shoots from different explants was investigated, so an efficient protocol was developed for in vitro regeneration of ‘Garnem’ hybrid rootstock These outputs of the study can be a reference resource for future in vitro and biotechnological studies on the rootstock in question. The differences of PGR in MS medium culture containing node explants infinite (0.5-2.0 mg / l) BA (benzyladenine) were investigated. Upon the research, it was observed that the number of shoots andproliferationwere achieved in explants of nodal cuttings that were taken to culture in MS medium containing 2.0 mg / l BA. It has been determined that the most effective culture medium for the elongation of shoot length is MS medium containing 0.5 mg / l BA, 30 g / l sucrose and 5.5 g / l agar. Shoots growing in length were transferred to a new culture with ½ MS medium 0.5-2.0 mg / l IBA (indole-3-butyric acid) to be rooted. While rooting at a rate of 42.8% was achieved in ½ MS medium containing 2 mg / l IBA, 47.2% of rooted plantlets were acclimatized to ex- vitro conditions. Rooted plantlets obtained under in vitro conditions were transferred to plastic containers with 3 different environments in order to get accustomed to external conditions. At the end of the 8th week, the vitality rates of the plantlets were determined. While the viability rate of the plantlets transferred to the medium containing peat: perlite at the ratio of 1: 1 was found to be 47.2%, the viability rate of the plantlets in the environment containing only perlite was found to be 32.8%, and the viability rate of the plantlets in the environment containing only peat was found as 23.6%
