in order to determinate the self–incompatibility and the most suitable pollinizer for esfahan commercial quince cultivar, the effects of four different pollinizer treatments ((km1, pk2, kvd2, nb4), as self pollination and open pollination) on fruit set and quantitative and qualitative characteristics of commercial quince fruits of isfahan were studied in a randomized complete block design with ...

The breeding system and pollination ecology of Paeonia broteroi (Paeoniaceae), a selfcompatible, perennial herb, which produces few flowers (1-8) per season, are described in wo populations in mountains of southern Spain. Experimentally self-pollinated flowers yielded a significantly lower seed set (6-18%) than cross-pollinated flowers (23-29%), but the latter did not differ in seed set from op...

For many species of conservation significance, multiple factors limit reproduction. This research examines the contributions of plant height, number of flowers, number of stems, pollen limitation and seed predation to female reproductive success in the deceit-pollinated orchid, Cypripedium candidum. The deceptive pollination strategy employed by many orchids often results in high levels of poll...

Plant S-phase kinase-associated protein 1 (SKP1) genes play crucial roles in plant development and differentiation. However, the role of SKP1 in citrus is unclear. Herein, we described a novel SKP1-like gene, designated as CrWSKP1, from "Wuzishatangju" (Citrus reticulata Blanco). The cDNA sequence of CrWSKP1 is 779 base pairs (bp) and contains an open reading frame (ORF) of 477 bp. The genomic ...

Even though floral scent is of major importance for pollinator attraction, it less investigated than other traits. Previous studies suggest the joint exploration olfactory and visual cues to understand plant–pollinator interactions. We flower scents in Collinsia heterophylla, a bee-pollinated, annual herb with mixed-mating system combining self- outcross-pollination. In Collinsia, size developm...

Chinese pine seed orchards are in a period of transition from first-generation to advanced-generations. How to effectively select populations for second-generation seed orchards and significantly increase genetic gain through rational deployment have become major issues. In this study, we examined open- and control-pollinated progeny of the first-generation Chinese pine seed orchards in Zhengni...
