Prunus fruit trees of the Rosaceae family exhibit S-RNase-based gametophytic self-incompatibility (GSI), which enables pistils to reject self-pollen by suppressing pollen tube elongation. In other plant species with GSI, it has been shown that this suppression consists two steps: first, slowing down elongation in middle part style and second, complete arrest involving programmed cell death. To ...

Gametophytic self-incompatibility (GSI) is an outcrossing mechanism in flowering plants that is genetically controlled by 2 separate genes located at the highly polymorphic S-locus, termed S-haplotype. This study characterizes a pollen part mutant of the S(1)-haplotype present in sour cherry (Rosaceae, Prunus cerasus L.) that contributes to the loss of GSI. Inheritance of S-haplotypes from reci...

It was investigated whether premature fruit abscission in Prunus avium L. was triggered by a reduction in polar auxin transport (PAT). The capacity of pedicels to transport tritiated IAA ([3H]-IAA) via the PAT pathway was measured at intervals throughout flower and fruit development. The extent of passive diffusion, assessed by concurrent applications of [14C]-benzoic acid ([14C]-BA), was negli...

Bu çalışmada, Türkiye kiraz budama artıklarının enerji potansiyelinin hesaplanmasında kullanılabilecek gerçekçi katsayısının belirlenmesi hedeflenmiştir. amaçla Çanakkale ilinde 3 farklı çeşidi ve her çeşit için 2 yaş grubunda, toplam 30 ağacında çalışmaları yapılmıştır. Elde edilen veriler ile artık miktarı katsayısı belirlenmiştir. Yürütülen faaliyetlerinde, üç iki grubundan elde miktarının a...

Sweet cherry (Prunus avium L.) is one of the most important stone fruit species in Bulgaria. The known to be susceptible more than 30 viruses. Among them are prune dwarf virus (PDV), prunus necrotic ringspot (PNRSV) and apple mosaic (ApMV), ilarviruses. Testing for these viruses required certification schemes order provide virus-tested propagated material fruit-growing industry prevent their di...
