Biological and Agronomical Characteristics of Local and Introduced Plum (Prunus domestica L.) Cultivars in Georgia
Plum local varieties and forms are widespread in all regions of Georgia. Despite the wide dissemination of this crop, the number of cultivars is not quite a lot. Due to this reason, study of cultivars has been carried out in a collection plot of the Scientific-Research Center of Agriculture, in village Jighaura. Eight plum (Prunus domestica L.) cultivars including: Amers, Bluefree, Chanchuri, E...

Spatial and Temporal Assessment of Pollen- and Seed-Mediated Gene Flow from Genetically Engineered Plum Prunus domestica
Pollen flow from a 0.46 ha plot of genetically engineered (GE) Prunus domestica located in West Virginia, USA was evaluated from 2000-2010. Sentinel plum trees were planted at distances ranging from 132 to 854 m from the center of the GE orchard. Plots of mixed plum varieties and seedlings were located at 384, 484 and 998 m from the GE plot. Bee hives (Apis mellifera) were dispersed between the...
متن کاملGamma-irradiated pollen induces the formation of 2n endosperm and abnormal embryo development in European plum (Prunus domestica L., cv. `̀ Rainha
The effect of gamma radiation on pollen germination capacity and pollen tube growth was evaluated in vitro and in situ conditions. In vitro experiments, revealed that irradiation signi®cantly affects pollen viability, mainly for levels higher than 200 Grays (Gy). Also, for levels higher than 200 Gy, in situ observations showed that no pollen tube reached the ovule. Fruit set results con®rmed th...
متن کاملThe Influence of Viral Infections on Antioxidant Levels in the Genetically Modified Plum Variety “honeysweet“ (prunus Domestica L.)
It is well-known that polyphenolic compounds are found abundantly in fruit, but various kinds of diseases lower these levels. This work measures total polyphenolic content, antioxidant activity and the levels of specific important antioxidants in fruits of the genetically modified (GM) plum variety HoneySweet, trees which were previously inoculated with a range of different virus infections. Th...
