Abstract The aim was to determine the ideal concentration of sucrose along with number plants per container in face micropropagation blueberry under TIS. In experiment conducted (0, 10, 20, e 30 g L-1), we utilized a WPM medium, taking into account explants container. For dealing plant density, same medium 20 L-1 conjunction 30, 40, 50 and 60 used. After 90 days from installation trial, followi...

Wild bees provide important pollination services to agroecoystems, but the mechanisms which underlie their contribution to ecosystem functioning--and, therefore, their importance in maintaining and enhancing these services-remain unclear. We evaluated several mechanisms through which wild bees contribute to crop productivity, the stability of pollinator visitation, and the efficiency of individ...

Abstract Ralstonia pseudosolanacearum (Rps), previously known as R. solanacearum phylotypes I and III is one of the causal agents bacterial wilt, a devastating disease that affects more than 250 plant species. Emerging Rps strains were identified infecting new hosts. P824 strain was isolated from blueberry in Florida. including PD7123 hybrid tea roses several countries through Europe. P781 repr...

Blueberry has high nutritional value and is favored by consumers, so the planting area increasing. However, due to influence of climate conditions edaphic environment, achieving production healthy growth blueberries become a major problem. In this study, we collected soil blueberry plants which had normal limited determine underlying causes poor characterizing pH, EC, enzyme activities microbio...

in this study, blueberry essential oil as a core material was microencapsulated with inulin and β-cyclodextrin at a ratio of 1:5 (core: wall). oil in water nano-emulsions were prepared by ultrasonic liquid processors and then transformed to encapsulate powder in spray dryer. dried powder was stored at 4 ˚c in refrigerator for determining moisture, encapsulation efficiency and morphology prop...

To maximize yield of pollination-dependent agricultural crops, farmers must ensure that sufficient pollinators are present when flowers are open and viable. We characterized and compared the lower development threshold temperature, bloom phenology, and flower viability of five common cultivars of highbush blueberry (Vaccinium corymbosum L.) to enable prediction of when flowers would be availabl...

Controlled ice nucleation is an important mechanism in cold-hardy plant tissues for avoiding excessive supercooling of the protoplasm, for inducing extracellular freezing and/or for accommodating ice crystals in specific tissues. To understand its nature, it is necessary to characterize the ice nucleation activity (INA), defined as the ability of a tissue to induce heterogeneous ice nucleation....

Blueberry (Vacciniumcorymbosum interspecific hybrids) production in soilless substrates is becoming increasingly popular. Soilless have low pH buffering capacity. plants preferentially take up ammonium, which acidifies the rhizosphere. Consequently, where blueberry are grown exhibit a tendency to get acidified over time. Agricultural lime (CaCO3) commonly used raise soil and substrate other cro...

Foliar fertilization makes it possible to quickly provide plants with essential nutrients, mainly micronutrients, which can significantly improve the quality of yields. The aim this study was evaluate effect foliar fertilizers containing calcium and microelements on yielding fruit highbush blueberry (Vaccinium corymbosum L.). A two-year carried out in western Poland an experimental production p...

In a 2-yr field study, mature orchard plants of rabbiteye blueberry (Vaccinium ashei Reade variety 'Climax'), plus potted pollenizers ('Premier') were caged with varying densities of honey bees (0, 400, 800, 1,600, 3,200, 6,400, or 12,800 bees plus open plot) during the bloom interval. The rate of legitimate flower visits tended to increase as bee density increased within a range of 400-6,400 b...
