A two-year trial was conducted during 2016 and 2017 seasons in an apricot (Prunus armeniaca L.) commercial orchard located at Cerignola (Foggia province, Puglia region, Southern Italy, 41°15'49''N; 15°53'59''E; 126 a.s.l.). The effects of three plant biostimulants (Hendophyt®, Ergostim® Radicon®, based on biopolymers polysaccharides, carboxylic acids humic-fulvic acids, respectively) compared w...

A facilidade de propagação vegetativa por estacas herbáceas é uma das características almejadas no trabalho seleção porta-enxertos Prunus spp. melhor adaptados às condições edafoclimáticas do Rio Grande Sul. O objetivo presente foi avaliar a viabilidade técnica da 17 seleções pessegueiro [Prunus persica (L.) Batsch] sob câmara nebulização intermitente, adotando-se três cultivares como referênci...

Peaches (Prunus persica cv. Yanhong) were fumigated with carbon monoxide (CO) at 0, 0.5, 5, 10, and 20 μmol/L for 2 hours. The result showed that low concentration CO (0.5-10 μmol/L) might delay the decrease of firmness and titrable acid content, restrain the increase of decay incidence, and postpone the variation of soluble solids content, but treating peaches with high concentration CO (20 μm...

Tetraploid sour cherry (Prunus cerasus L.) exhibits gametophytic self-incompatibility (GSI) whereby the specificity of self-pollen rejection is controlled by alleles of the stylar and pollen specificity genes, S-RNase and SFB (S haplotype-specific F-box protein gene), respectively. As sour cherry selections can be either self-compatible (SC) or self-incompatible (SI), polyploidy per se does not...

Individual groups of peach (Prunus persica [L.] Batsch) seedlings stressed to -17, -26 and -36 bars recovered to control levels within 1, 3, and 4 days, respectively. Stomatal resistance was significantly correlated with both leaf water potential and net photosynthesis. In seedlings stressed to -52 bars, leaf water potential and stomatal resistance recovered sooner than net photosynthesis, desp...

Sakuranetin is flavonoid phytoalexin that serves as a plant antibiotic and exists in Prunus and several other plant species. Recently, we identified the anti-inflammatory effect of Prunus yedoensis and found that there were few studies on the potential anti-inflammatory activity of sakuranetin, one of the main constituents of Prunus yedoensis. Here, we isolated peritoneal macrophages from thiog...

Research to date indicates that post-transcriptional gene silencing (PTGS) is an effective strategy for the development of stable high-level resistance to Plum pox virus in plum. Field tests in Poland, Romania, and Spain show that after 5–6 years of natural aphid vectored inoculation, trees of the PTGS clone C5 remain virus-free. The effectiveness of transgene-based PTGS for imparting potyvirus...
