in this study, we assessed the relative contribution of organic and inorganic solutes to osmotic adjustment (oa) in three almond rootstocks subjected to four levels of soil salinity. the results showed that leaf water and osmotic potentials were affected by salinity in gf677 and bitter almond, but less so in gn15, suggesting a higher selectivity for k+ and ca2+ against na+ in this latter rootst...

Stereomicroscopic observations using oblique illuminations revealed the presence of two types of movement trails by Xylella fastidiosa strains (A- and G-genotypes) isolated from almond-leaf scorch samples on the surface of PW and PD3 culture media. The A-genotype strains showed curved motility trails, and the G-genotype strains showed straight motility trails. Haloes were found around some G-ge...

cyanogenesis in prunus species produces‎‏ ‏cyanogenic glycosides such as‏ ‏monoglycoside ‎prunasin and digelicosede amygdalin. despite the mechanism of almond bitterness inheritance ‎has been known, biosynthesis cycle of cyanogenic compounds among different genotypes is still ‎unclear. total soluble proteins of fruits was extracted from collected sweet and bitter almond ‎genotypes and was studi...

in fruit trees damage of frost and freezing is depended to time of chillhng and tree phonological stage. almond (prunus amygdalus b. (and apricot (p. armeniaca l.) cultivars are usually the first fruit trees to bloom and susceptible to damaging frosts in the early spring. a study was conducted on different types of almond and apricot cultivars in order to investigation the main factors related ...

The almond [Prunus dulcis (Mill.) D.A. Webb] is normally self-sterile, requiring orchard placement of pollinizer cultivars and insect pollinators. Honeybees are the primary pollinators utilized, but climate change higher frequency extreme weather events have reduced their availability to levels insufficient meet demands current anticipated acreage. incorporation self-fruitfulness may eliminate ...

Almond is a highly heterozygous species with a high number of S-alleles controlling its gametophytic self-incompatibility system (GSI). In this work we have analysed Spanish local almond cultivars for S-RNase allele diversity. By cloning and sequencing five new S-RNase alleles were identified: S31 (804 bp) in 'Pou de Felanitx' and 'Totsol', S32 (855 bp) in 'Taiatona', S33 (1165 bp) in 'Pou d'Es...
