Investigations On The Pollen Viability, Germination Capability And Production Of Pollen, Pollen Tube Growth In Some Selected Turkish Almond Types And Texas Cultivar Under Adana Ecological Conditions, Sinan Eti̇, Sevgi Paydaş, Ayzin B. Küden, Nurettin Kaşka, Şükriye Kurnaz, Mürüvvet Ilgin

Turkish Journal of Agriculture and Forestry

In this research the fertilization biologies of mid and late flowering 4 almond types (101-9, 101-13, 101-23 and 106-1) selected from different parts of Turkey and Texas cultivar were studied. For this purpose, first of all, pollen viability tests with TTC and FDA and pollen germination tests in 0 %, 5 %, 10 %, 15 % and 20 % sucrose mediums by hanging drop method were performed. On the other hand, the amount of pollen production and their morphological homogenity levels were determined. In addition, besides self and open pollinations with cross pollinations the pollen tube growth rates were investigated. …

The Effect Of Different Cutting Stages And Seeding Rates On Forage And Seed Yields Of Narbonne Vetch (Vicia Narbonensis L.), A. Emin Anlarsal Jan 1996

The Effect Of Different Cutting Stages And Seeding Rates On Forage And Seed Yields Of Narbonne Vetch (Vicia Narbonensis L.), A. Emin Anlarsal

Turkish Journal of Agriculture and Forestry

The aim of this study was to determine the most suitable seeding rate and cutting stage of Narbonne Vetch (Vicia narbonensis L.) for forage and seed production. This experiment was arranged as split plot design with three replications for forage production. Cutting stages (early bloom, middle bloom, beginning of podding) were main plots and seeding rates (16, 18, 20, 22, 24 kg/da) were considered as sub plots. Another experiment was arranged in Randomized blocks to determine the effect of same seeding rates on seed yield. Plant height, green froage yield and hay yield increased seeding rate. Hay yield decreased with …

A Research On The Effects Of Fermentation Type And Additives On Quality And Preservation And Development Of Adequate Technique In Brined Vine-Leaves Production, Fikri Başoğlu, İsmet Şahi̇n, Mihriban Korukluoğlu, Vildan Uylaser, Arzu Akpinar Jan 1996

A Research On The Effects Of Fermentation Type And Additives On Quality And Preservation And Development Of Adequate Technique In Brined Vine-Leaves Production, Fikri Başoğlu, İsmet Şahi̇n, Mihriban Korukluoğlu, Vildan Uylaser, Arzu Akpinar

Turkish Journal of Agriculture and Forestry

Various processes were applied to vine-leaves (used in stuffed vine-leaves) to maintain their colour, taste and aroma. Lactic acid, citric acid or salicilic acid of 0.25 % each were added into brine for fermentation of Sultani, Alphons and Erenköy beyazi vine-leaves. Fermentations were carried out in two ways. First one was spontaneous fermentation but in the second one Lactobacillus brevis, Lactobacillus plantarum and Pediococcus pentosaceus were added in a rate of 3 % as starters. Colour, salt (%), pH, acidity (%), reduced sugar (%) analyses were carried out in fresh vine-leaves. Changes in the amount of salt (%), acidity (%), …

The Effects Of Bottom Heating On Rooting Of Hardwood Cuttings With Different Number Of Buds Of Some Grapevine Rootstocks Resistant To Nematodes, Semih Tangolar Jan 1996

The Effects Of Bottom Heating On Rooting Of Hardwood Cuttings With Different Number Of Buds Of Some Grapevine Rootstocks Resistant To Nematodes, Semih Tangolar

Turkish Journal of Agriculture and Forestry

In this experiment, the effects of bottom heating on rooting of hardwood cuttings with different number of buds of Dog Ridge, Salt Creek, Harmony, 1616 C and 1613 C which are nematode-resistant rootstock varieties were investigated, and rooting percentage, degree of rooting, total number and length of roots were determined. The highest values were obtained from the bottom heated cuttings with had three and four buds. The results showed that 1616 C had superior rooting ability than the other rootstocks in all characteristics tested. The rooting percentage was about 80-90 % and the rooting quality was sufficient, bottom-heated Salt Creek …

Effect Of Colchicine Treatment With Different Doses And Periods On In Vitro Chromosome Doublication In Haploid Watermelon, Nebahat Sari, Kazım Abak Jan 1996

Effect Of Colchicine Treatment With Different Doses And Periods On In Vitro Chromosome Doublication In Haploid Watermelon, Nebahat Sari, Kazım Abak

Turkish Journal of Agriculture and Forestry

Differents colchicine doses (0.5 % and 1 %) and treatment periods (1, 2, 4 and 6 hours) were tested in vitro conditions in order to obtain dihaploid lines from parthenogenetic haploid plants which achieved by irradiated pollen. Treatments were made to 3-4 weeks age in vitro microcuttings of Sugar Baby, Halep Karasi and Crimson Sweet varieties. 64 percent of the plants treated with 0.5 % colchicine stayed alive and 56 % of the plants were developed into a new plant. At the doses of 1% the rate of alive and growing plant decrease to 40 %. As for as the …

Changes In Water Content And Other Soil Properties In Different Previous Crops-Wheat Rotation Systems Under Ankara Conditions, Didar Eser, M. Sait Adak, Günal Akbay, Andreas Biesantz, Atilla Atalay, Paul Limberg Jan 1996

Changes In Water Content And Other Soil Properties In Different Previous Crops-Wheat Rotation Systems Under Ankara Conditions, Didar Eser, M. Sait Adak, Günal Akbay, Andreas Biesantz, Atilla Atalay, Paul Limberg

Turkish Journal of Agriculture and Forestry

According to the results obtained from two years rotation experiment, which was carried out under Ankara-Haymana dryfarming conditions during 1991-1993, conclusions can be summarized as follows: Soil water contents measured during vegetation period as well as at harvest time of six previous crops were significantly different in the first year of the rotation. At harvest time of previous crops and planting time of wheat, higher soil water content found in fallow plots in comparison to winter sown legumes (lentil, vetch, pea and Hungarian vetch). Oil radish and mustard as other previous crops, led to the lowest soil water content. In …

The Effects Of Different Doses Of Nitrogen And Plant Densities On Some Agronomic And Technologic Characteristic Of Lavender (Lavandula Angustifolia Mill.), Ayhan Ceylan, Emine Bayram, Nazan Özay Jan 1996

The Effects Of Different Doses Of Nitrogen And Plant Densities On Some Agronomic And Technologic Characteristic Of Lavender (Lavandula Angustifolia Mill.), Ayhan Ceylan, Emine Bayram, Nazan Özay

Turkish Journal of Agriculture and Forestry

The effects of different doses of nitrogen (0, 6, 12, 18 kg/da N) and various densities of plants (20x20, 30x30, 40x40, 60x60 cm) on the yield and quality traits of (Lavandula angustifolia Mill.) were investigated in the experiment conducted for four years in under ecological conditions of Bornova. The quantity of Flores lavandulae was defined on average 234 kg/da in 1988, 286 kg/da in 1989, 142 kg/da in 1990, the density of plants increased the yield significantly in terms of statistical. Maximum yield was obtained at variation of 30x30 cm (11.100 plant/da). The essential oil rates ranged on average from …

The Effects Of Group Selection On The Characteristics And Use Of Cavity Trees And Snags, Mary Lynn Lambert Jan 1996

The Effects Of Group Selection On The Characteristics And Use Of Cavity Trees And Snags, Mary Lynn Lambert

Masters Theses

I studied the effects of group selection tree harvest on the availability, composition, and use of cavity trees, snags and cavities in the Ozark Mountains of northwestern Arkansas. Sixteen plots dominated by oaks and hickories that were 70-102 years old were surveyed prior to harvest. Tree species, diameter, height and number of visible cavities were recorded. In addition, 192 cavity trees were marked for wildlife observations during the summer and winter. Subsequently, plots were harvested by commercial contractors to either 15 or 19 m2/ha basal area, using either free or structural control thinning methods. A complete survey of …
