Pollination by native bees increases fruit mass without changing protein content in snap beans [PDF]

open access: yesScientia Agricola
: Insects play a vital role in agricultural production by enhancing both the quantity and quality of fruits and seeds in a wide range of allogamous and autogamous crops. The common bean (Phaseolus vulgaris) exemplifies an autogamous crop that can benefit

THE EVOLUTION OF AUTOGAMY IN SPECIES OF THE MUSTARD GENUSLEAVENWORTHIA [PDF]

open access: yesEvolution, 1977
In about 80% of all species of hermaphroditic flowering plants the pollen is incapable of germinating on the styles of the flowers that produce it, a condition known as selfincompatibility (Fryxell, 1960). The genetic control is usually simple, one-locus, and multiallelic (Lewis, 1954) although more complex two-locus systems are known (Lundquist, 1975).

Assessment of Pollen Production, Pollen Viability, Autofertility and Paternal Success in Faba Bean (Vicia faba L.) for Better Exploitation of Grain Yield Heterosis

open access: yesPlant Breeding, EarlyView.
ABSTRACT In animal‐pollinated plants, pollen dispersal depends on several plant and animal characteristics that can influence the paternal success of a plant. Paternal success affects the genetic contribution of a genotype to the next generation, which is relevant to plant breeding.

In Vivo Propagation of Root Explants of the Dandelion Species Taraxacum kok‐saghyz, Taraxacum officinale and Their Interspecific Hybrids

open access: yesPlant Breeding, EarlyView.
ABSTRACT The dandelion species Taraxacum kok‐saghyz is a promising new crop for natural rubber production and is currently in the early stages of the breeding process. To support these efforts, the multiplication and conservation of defined genotypes are crucial.

The dynamics of Listera ovata populations on mineral islands in the Biebrza National Park

open access: yesActa Societatis Botanicorum Poloniae, 2014
Observations of two isolated populations of Listera ovata (Oparzelisko and Zabudnik) were conducted for 7 years in the Biebrza National Park. The studied populations differed in size, proportion of flowering individuals and effectiveness of reproduction.
