Evaluation Of Cone And Seed Quality Of Siberian Stone Pine (Pinus Sibirica Du Tour) For Plus-Tree Selection, Svetlana Velisevich, Alexander Popov Jan 2022

Evaluation Of Cone And Seed Quality Of Siberian Stone Pine (Pinus Sibirica Du Tour) For Plus-Tree Selection, Svetlana Velisevich, Alexander Popov

Turkish Journal of Agriculture and Forestry

Siberian stone pine (Pinus sibirica Du Tour) is a cone-bearing species with outstanding nutritious seeds, health-supporting properties, and nut oil. Currently, the main volume of pine nuts is harvested in natural forests, which causes damage to ecosystems. The best solution to this problem would be harvesting nuts on special pine nut plantations established on the basis of high-seeding clones. However, it is hampered by the low efficiency of the existing methods for assessing plus-tree productivity. This work focused on cone analysis in two sites used for plus-tree selection: a 42-year-old sparse forest plantation and a 186-224-year-old closed natural forest. The …

Houba Retrotransposon-Based Molecular Markers: A Tool For Variation Analysis In Rice, Gözde Yüzbaşioğlu, Si̇bel Yilmaz, Nermi̇n Gözükirmizi

Turkish Journal of Agriculture and Forestry

Rice is one of the most important crop plants as well as a model organism used for genetic studies. Transposons, especially retrotransposons, have a significant impact on the rice genome. A considerable percentage of the rice genome is composed of transposons (about 35%). Thus, transposons are an important internal factor for the genome evolution of rice varieties. In this study, we performed fing?erprint analyses of 37 Oryza sativa L. Cultivars using an IRAP marker. For this purpose, we designed IRAP primers specific to Houba (Tos5/Osr13), RIRE1 and Hopi (Osr27), and Osr30 retrotransposons, the most abundant retrotransposons in the rice genome. …

Comparison Of Manual Measurements And Computer-Assisted Image Analysis In Fish Morphometry, Miloslav Petrtyl, Lukás Kalous, Devri̇m Memi̇ş

Turkish Journal of Veterinary & Animal Sciences

Fish usually have a simple body shape and many morphological characters can be easily obtained by 2-dimensional image analysis. Measuring errors are often analyzed using data from several researchers or repeated measurements, but the testing of accuracy and repeatability based on different methods has rarely been examined. Here we report the comparison of manual measurements using Proma 150D digital calipers and computer-assisted image analysis in LUCIA software to evaluate the accuracy of both methods and the suitability of digital images for exploration of fish morphology. Eighteen morphometric characters of 20 specimens of Prussian carp were examined by 2 researchers. The …

The Within-Tree Variation In Wood Density And Shrinkage, And Their Relationship In Populus Euramericana, Behzad Kord, Ali Kialashaki, Behrouz Kord

Turkish Journal of Agriculture and Forestry

The patterns of wood density and shrinkage in different directions in 22-year-old Populus euramericana trees from one clone were studied in an experimental plantation in Iran. Sample disks were taken from each tree to examine wood density and shrinkage variation from pith to bark at 5%, 25%, 50%, and 75% of total tree height. The results indicate that radial position and height significantly affected all wood physical properties. Within-tree wood density and shrinkage varied at each height level, decreasing along the stem from the base upwards. Moreover, within the samples, at the same height level wood density and shrinkage in …
