Impacts Of Logging And Prescribed Burning In Longleaf Pine Forests Managed Under Uneven-Aged Silviculture, Ferhat Kara, Edward Francis Loewenstein
Impacts Of Logging And Prescribed Burning In Longleaf Pine Forests Managed Under Uneven-Aged Silviculture, Ferhat Kara, Edward Francis Loewenstein
Turkish Journal of Agriculture and Forestry
The longleaf pine (Pinus palustris Mill.) ecosystem has historically been very important in the southeastern United States due to its extensive area and high biodiversity. Successful regeneration of longleaf pine forests requires an adequate number of well-distributed seedlings. Thus, mortality of longleaf pine seedlings during logging operations and prescribed burning appears to be important. Longleaf forests have been commonly managed using even-aged silvicultural methods, but, recently, interest in the use of uneven-aged (UEA) methods has increased in these forests. Research on the impact of UEA logging in longleaf forests is limited. In addition, the influence of overstory density on the …

In order to develop genotypes having a stable higher yield, it is necessary to characterize genetic resources based on drought adaptation, determine the suitable genotypes, and use them in breeding programs. This study was carried out in greenhouses, plant growth chambers, and research farms of the Faculty of Agriculture at Atatürk University. A total of 64 certified and local bread wheat genotypes were used to test survival after drought, coleoptile length, and seedling vigor. There were significant differences with respect to the selection parameters in this study. Seedling survival ranged from 18.5% to 51.1% and coleoptile lengths were 3974 mm. …
In Vitro Storage Of Some Pear Genotypes With The Minimal Growth Technique, Maqsood Ahmed, Muhammad Akbar Anjum
In Vitro Storage Of Some Pear Genotypes With The Minimal Growth Technique, Maqsood Ahmed, Muhammad Akbar Anjum
Turkish Journal of Agriculture and Forestry
Shoot cultures of 9 pear genotypes collected from different areas of Azad Jammu and Kashmir (northern Pakistan) were maintained on MS medium supplemented with 30 g L^{-1} of sucrose + 7 g L^{-1} of agar + 1 mg L^{-1} of BAP. For in vitro preservation shoot tips were excised from these cultures and transferred onto different media, i.e. full strength, ¼ strength, ½ strength MS medium, and full strength MS medium containing 2.5% or 3.5% (w/v) mannitol. The cultures were assessed for their survival after storage periods of 3, 6, 9, and 12 months. To test the regenerability of the …

Comparison Of Rooting Capabilities Of Turkish Tea Clones, Eyyüp Altindal, Fi̇kri̇ Balta
Turkish Journal of Agriculture and Forestry
In this study, single leaf cuttings of 10 Turkish tea (Camellia sinensis) clones Hamzabey-1, Ardeşen-1, Fener-3, Hayrat-1, Çiftekavak-1, Muradiye-10, Tuğlalı-10, Gündoğdu-3, Kömürcüler-1 and Derepazarı-7 were rooted under greenhouse conditions at seven different collection times without using any plant hormones. The cuttings were collected on 28 August, 4 September, 11 September, 19 September, 25 September, 4 October and 10 October. Rooted plants were removed from rooting medium in mid-May. Plant survival, root dry weight, shoot dry weight and shooting percentage were recorded depending on the tea clones and collection times. The highest survival percentage by mean values of collection times was …
