This study was conducted during 2011 and 2012 to evaluate the effect of 1-aminocyclopropane-1-carboxylate (ACC) deaminase-containing, N 2 -fixing and P-solubilizing bacteria on the yield and morpho-physiological parameters of strawberry. A total of 8 applications at the trial set, with four water regimes were randomly distributed into the pots. The diminishing water supply caused a gradual decrease in the plant growth,

Kafkas Univ Vet Fak Derg, 23 (6): 865-870, 2017. DOI: 10.9775/kvfd.2017 AbstractIn this study, wintering ability and some physiological properties of Buckfast, Carniolan, Caucasian and Erzurum honeybee genotypes were investigated in Eastern Anatolian conditions. During the wintering season of 2014, a total of 48 colonies, 12 from each of Buckfast, Carniolan, Caucasian and Erzurum honey bee genotypes, were taken from the equilibrated colonies of Langstroth type wooden hives for wintering. In the 2015 production period, a total of 43 colonies,11 from each of Buckfast, Carniolan, Erzurum genotypes and 10 from Caucasian genotype were used in the study. In the production season, the average number of combs covered with bees in genotype groups were found as 11.72±0.63,

Numerous flowering plants rely on bees for pollination. Any natural or anthropogenic factor that threatens colony survival can have a large impact on plant production. This study investigates the effects of manmade hives built from different materials and how these may influence colony growth. Ten each of three hive types were selected, wooden, polystyrene and composite insulated hives. Factors of adult bee numbers, brood development, nectar flow period weight gain, bee flight activity, aggression response, and honey yield were selected markers of hive development. Statistically, each hive type produced significant variation (p < .05). The greatest overall productivity across all factors was for insulated hives made of composite material, with honey production approximately 35% times that of wood, 14% times that of polystyrene and in terms of the development of honeybee colonies, the average of other hives is 10.2 times. HIGHLIGHTS Relative humidity and temperature are important environmental factors for honeybees. Insulated hives, increased honey yield. High temperature and humidity inside the hive made honeybees more aggressive.

2Geomagnetic field can be used by different magnetoreception mechanisms, for 3 3 navigation and orientation by honeybees. The present study analyzed the effects of magnetic 3 4 field on honeybees. This study was carried out in 2017 at the Bayburt University Beekeeping 3 5 Application Station. In this study, the effect of Electro Magnetic field (EMF) and electric field 3 6 (EF) on the time of finding the source of food of honeybees and the time of staying there were 3 7 determined. The honeybees behaviors were analyzed in the presence of external magnetic 3 8 fields generated by Helmholtz coils equipment. The Electro Magnetic field values of the coils 3 9 were fixed to 0 T (90mV/m), 50 T (118 mV/m), 100 T (151 mV/m), 150 T (211 mV/m), 4 0 200 T (264 mV/m). Petri dishes filled with sugar syrup were placed in the center of the coils.4 1 According to the study, honeybees visited at most U1 (mean =21.0 17.89 bees) and at least 4 2 U5 (mean =10.82 11.77 bees). Honeybees waited for the longest time in U1 (mean =35.27 4 3 6.97 seconds) and at least in U5 (mean =12.28 5.58 seconds). According to the results 4 4obtained from this first study showed that honeybees are highly affected by electromagnetic 4 5 radiation and electric field. 4 6
