Stamen development and winter dormancy in apricot (Prunus armeniaca).
BACKGROUND AND AIMS In temperate woody perennials, flower bud development is halted during the winter, when the buds enter dormancy. This dormant period is a prerequisite for adequate flowering, is genetically regulated, and plays a clear role in possibly adapting species and cultivars to climatic areas. However, information on the biological events underpinning dormancy is lacking. Stamen deve...
متن کاملPurification and Characterization of Latent Polyphenol Oxidase from Apricot (Prunus armeniaca L.)
Polyphenol oxidase from apricot (Prunus armeniaca) (PaPPO) was purified in its latent form (L-PaPPO), and the molecular weight was determined to be 63 kDa by SDS-PAGE. L-PaPPO was activated in the presence of substrate at low pH. The activity was enhanced by CuSO4 and low concentrations (≤ 2 mM) of SDS. PaPPO has its pH and temperature optimum at pH 4.5 and 45 °C for catechol as substrate. It s...
متن کاملOsmotic Drying of Apricot (Prunus armeniaca) in Sucrose Solution
Osmotic drying is a process of partial removal of water by submersing fruits in sucrose solution. Th e goal of this paper is to examine kinetic features of osmotic drying of apricot halves in sucrose solution. For osmotic drying of apricot halves in a thick immovable layer, a planned experiment was conducted. Experimental results were used to create an empirical model of osmotic drying kinetics...
متن کاملIn Vitro Embryo Culture of Apricot, Prunus armeniaca L. cv. Hacıhaliloğlu
An in vitro zygotic embryo germination protocol was developed for apricot (Prunus armeniaca L. “Hacıhaliloğlu”). A hundred percent of germination was obtained when isolated embryos were cultured in vitro, a result alike those reported in the literature with traditional dormancy breaking treatments. In vitro seedling development was optimal in a modified full-strength Murashige and Skoog (1962) ...
متن کاملAntioxidant and antimicrobial activities of bitter and sweet apricot (Prunus armeniaca L.) kernels.
The present study describes the in vitro antimicrobial and antioxidant activity of methanol and water extracts of sweet and bitter apricot (Prunus armeniaca L.) kernels. The antioxidant properties of apricot kernels were evaluated by determining radical scavenging power, lipid peroxidation inhibition activity and total phenol content measured with a DPPH test, the thiocyanate method and the Fol...
