Modern almond growing travels on the tracks of super-high density (SHD). Born in 2010, it has already reached 6700 ha planted all over world. This new cultivation system needs to define efficient agronomic techniques order identify as a “Super-Efficient System”. Among these, choice cultivar is crucial technique and key factor for sustainability. The purpose this study was compare different cult...

The problem of aggregation processes in alignments is the subject of a paper published recently in a Statistical Physics Journal (Physica A230, 174-188, 1996). Two models are presented and discussed in that paper. First the energy landscape model proposed by Axelrod and Bennett (B. J. Pol. S. 23, 211-233, 1993), is analysed. The model is shown not to include most of its claimed results. Then a ...

Almonds are one of the most popular nuts, cultivated in countries with Mediterranean climates. In an almond orchard self-incompatible cultivar ‘Ferragnes’ Greece, a tree different morphological characteristics and signs self-compatibility was observed. The aim this study to phenotype, investigate trait, elucidate phylogenetic background tree, named ‘Mars’. Morphological traits kernel nut were m...

abstract salinity tolerance is one of the major factor influencing crop productivity in arid and semi-arid areas. the salinity tolerance of fruit trees can be enhanced through the use of tolerant rootstocks. this experiment was conducted to investigate the effects of salinity stress and rootstock on the growth, photosynthetic rate and nutrient concentrations of almond (prunus dulcis miller.) cv...

Self-incompatibility in almond and Prunus species is an important trait that prevents self-fertilization. Selfincompatibility in almond is controlled gametophytically by the multiallelic S-locus. Present study was done in order to identification and preliminary selection of self compatible progenies resulted from controlled crosses in almond using specific primer SfF/SfR. Some important morphol...

boron (b) toxicity is an important disorder that can limit plant growth in arid and semi-arid environments. it has been proven that use of tolerant rootstocks impede b uptake or transport to the aerial portions of plants. this may alleviate b toxicity in the scion, consequently improves the tolerance to excess b in the root zone. an experiment was conducted to find the effects of b toxicity on ...

Conventional RNA isolation methods optimised for pine seedlings have been shown to produce poor quality RNA when applied to needles of adult pine trees. We describe here a modified procedure to isolate high pure RNA from needles of thirty-year-old maritime pines, exhibiting high levels of phenolics, polysaccharides and RNases. Major changes were the inclusion of proteinase K in the extraction m...
