The current theory of pecan [Carya illinoinensis (Wangenh.) C. Koch] alternate bearing is the ‘‘growth regulator–carbohydrate theory’’ in which flowering is first controlled by growth regulators produced by fruit and leaves, and then by the size of the carbohydrate pool near budbreak. Lack of nitrogen (N) reserves has also been proposed to be limiting after large crops, thus reducing return blo...

An efficient protocol was achieved for rapid propagation of Wedelia chinensis (Osbeck) Merr. through axillary bud proliferation and ex vitro rooting. Murashige and Skoog (MS) medium supplemented with benzyladenine (BA; 8.87 microM) and indole-3-butyric acid (IBA; 2.46 microM) was optimal for axillary bud proliferation, which developed a mean of 8.3 shoots/node. Excision and culture of node segm...

Leaf longevity determines the annual cost of replacing foliage biomass and influences water and nutrient budgets. Longevity is readily estimated in most evergreen species by annual bud scars along the shoot. However, some species with indeterminate growth do not show these annual markers, making estimation of longevity difficult. One of these species is the widespread and economically valuable ...

The purpose of the study was to identify inheritance traits economic and biological characteristics properties in hybrid progeny primocane raspberry. objects were 16 parental forms 15 combinations crosses with a total number 1008 seedlings. It is established that breeding raspberry predominant fruiting on annual shoots, there are certain difficulties obtaining high degree remontancy, early, fri...

An efficient and reproducible in vitro protocol for largescale multiplication of Liquorice (Glycyrrhiza glabra L.)has been described. Multiple shoots formation was significantly influenced by growth regulators, photoperiod,explant position, season of explant collection and culture passage. Nodal explants were collected atmonthly intervals to initiate in vitro cultures. The hig...

In our laboratory, bacterial contamination was detected in cultures of Pelargonium x hederaefolium ‘Bonete’ that had been subcultured continuously for several years. Two contaminating bacteria were isolated and identified by partial sequence analysis of 16S rRNA gene as Paenibacillus glycanilyticus and Lactobacillus paracasei. Antibiotic sensitivity testing was performed on the bacterial isolat...

Salinity is one of the most important problems that restrict cultivation of crops in arid and semi-arid regions. Pistachio (Pistacia vera L.) is one of the most important trees that grow in these restricts. In this greenhouse study, the effects of salinity on growth of pistachio rootstock Badami evaluated. Seedlings were grown in plastic bags containing perlite. Salinity was imposed, by adding ...
