Abstract Producing seeds from shallot flower requires proper pollination techniques to form pithy seeds. This study aims determine the effectiveness of several methods in producing true (TSS). The research was conducted Cilame Village, Ngamprah District, West Bandung Regency, Java at an altitude 900 m asl. used a completely randomized design (CRD) which consisted four treatments and six replica...

Peach Prunus persica (L.) Batsch is self-compatible and largely self-fertile, but under greenhouse conditions pollinators must be introduced to achieve good fruit set and quality. Because little work has been done to assess the effectiveness of different pollinators on peach trees under greenhouse conditions, we studied 'Okubo' peach in greenhouse tunnels near Beijing between 2012 and 2014. We ...

An understanding of the breeding systems and pollination of agriculturally important plants is critical to germplasm improvement. Breeding system characteristics greatly influence the amount and spatial distribution of genetic variation within and amongst populations and influence the rarity and extinction vulnerability of plant species. Many woody bamboos have a long vegetative period (20-150 ...

To understand the reproductive ecology of a plant species with both selfing and outcrossing systems, it is important to know how selfed individuals contribute maintenance population. Further, examination magnitude inbreeding depression after pollination essential for accurate measurement success. In this study, we investigated characteristics viable seeds seedlings Rhododendron kaempferi in reg...

In recent years, studies have been carried on the selection and breeding of melon to reduce its production cost. The F1 seeds this species are usually created by parental lines. Notably, lines separated from each other secure materials. However, there no establishing suitable conditions for storing pollen grains Japanese Cucumis melo L. study, C. were dried at 38 oC temperature, 1.5 hours, whic...

BACKGROUND AND AIMS Brassicaceae is one of the most diversified families in the angiosperms. However, most species from this family exhibit a very similar floral bauplan. In this study, we explore the Brassicaceae floral morphospace, examining how corolla shape variation (an estimation of developmental robustness), integration and disparity vary among phylogenetically related species. Our aim i...

We studied the relative role of inflorescence traits, flowering synchrony, and pollination context for infructescence and fruit initiation in two Spanish populations of Arum italicum, a species in which inflorescences are the pollination unit. In this species, a specialized inflorescence organ, the appendix, is important for pollinator attraction. However, the short floral longevity and the pro...

In recent years Petunia has become a promising model system for studying the genetics and evolution of pollination syndromes. Here we provide a brief introduction to the issue of pollination syndromes, explain why Petunia is a suitable model for its study, present useful background information about pollinators and plants, review recent studies, and discuss questions related to the genetics and...

Pollination is critical to fruit production, but the interactions of pollination with plant resources on a plant's reproductive and vegetative features are largely overlooked. We examined the influences of pollination, irrigation and fertilisation on the performance of almond, Prunus dulcis, in northern California. We used a full-factorial design to test for the effects of pollination limitatio...

During the course of greenhouse studies, an unexpected sunflower mutant resulting from an interspecific cross of the wild perennial Helianthus divaricatus with cultivated HA 89 was found. In this mutant, dormancy is not induced in the developing embryo. Instead, developing seeds of the mutant sunflower begin to germinate in the head about 40 days after pollination (Fig. 1). Others have reported...
