It has been proposed that a pool of amino N, whose size is determined by aboveground N demand, cycles in the plant and regulates soil N uptake by exerting an inhibitory effect at the root level. Several experiments were carried out to study this hypothesis in almond trees [Prunus dulcis (Mill.) D.A. Webb]. Based on the evidence found, there is an association, at the whole tree level, between sa...

The acyclic polyol sorbitol is a primary photosynthetic product and the principal photosynthetic transport substance in many economically important members of the family Rosaceace (e.g. almond [Prunus dulcis (P. Mill.) D.A. Webber], apple [Malus pumila P. Mill.], cherry [Prunus spp.], peach [Prunus persica L. Batsch], and pear [Pyrus communis]). To understand key steps in long-distance transpor...

the genetic diversity among 56 almond (prunus dulcis) genotypes was analysed using 35 microsatellite markers and 14 morphological traits. analysis of morphological traits revealed a wide range of variation among the studied genotypes. out of 35 simple sequence repeats (ssrs) markers, 25 were polymorphic, producing 215 alleles that varied from 2 to 16 with an average of 8.76 alleles per locus. r...

The anatomy of Prunus dulcis was analyzed by applying several differential staining techniques and light microscopy. Prunus dulcis seed has a thin and structurally complex seed coat, with lignified cellulosic tissue. The embryo has two voluminous cotyledons. Cotyledon cells have a high number of protein and lipid bodies, some of which have phytin. The provascular tissue, located in the cotyledo...

Hybridization has played a central role in the evolutionary history of domesticated plants. Notably, several breeding programs relying on gene introgression from the wild compartment have been performed in fruit tree species within the genus Prunus but few studies investigated spontaneous gene flow among wild and domesticated Prunus species. Consequently, a comprehensive understanding of geneti...

The purpose of the presented article is to establish features obtaining an aseptic culture regenerants Prunus dulcis in vitro. Since impact climate change becoming increasingly large-scale Ukraine, one urgent problems that hinders humanity, both terms agro-ecology and food, need diversify traditional agriculture. Mydal valuable promising nut crops thanks which it possible climatic risks listed ...

The work, based on the results of original research and analysis literary sources, presents peculiarities structure flowers their formulas a number subtropical plants that are grown in open ground collection plots «Garden Subtropical Fruit Cultures» «Shaped Garden» Khorolsky Botanical Garden (Poltava Region) Sered them, 11 species already flowering fruiting collection, rest still growing. These...

Inorganic copper is used as a broad-spectrum fungicide and bacteriocide on a variety of agricultural crops. After application, the copper residue typically accumulates in the upper 15 cm of soil. Data from the California Pesticide Use Reports were used to estimate the augmentation of copper in the soil that resulted from pesticide applications for the six years from 1993 to 1998 on 12 crops tha...
