Comparative reproduction mechanisms of three species of Ocimum L. (Lamiaceae)

Acta Agrobotanica, 2016
Ocimum species have a combination of reproductive system which varies with the locality and cultivar. We have studied here the reproductive mechanisms of five variants of three Ocimum species in Nigeria, namely: Ocimum canum Sims., O. basilicum L., and O.

An open-pollinated design for mapping imprinting genes in natural populations [PDF]

Briefings in Bioinformatics, 2014
With the increasing recognition of its role in trait and disease development, it is crucial to account for genetic imprinting to illustrate the genetic architecture of complex traits. Genetic mapping can be innovated to test and estimate effects of genetic imprinting in a segregating population derived from experimental crosses.

Variability of the data indicating the fertility of different plum varieties

International Journal of Horticultural Science, 2003
Self-fertility and fertility at conditions of open pollination in plum varieties is strictly determined by genetic factors. However, rates of fruit set are highly variable according to growing sites as well as to seasons, which may result from a couple ...

Morphological Characterization and Classification of Open-pollinated Sweet Corn Cultivars [PDF]

Journal of the American Society for Horticultural Science, 1995
Sweet corn is one of the most important vegetable crops in the United States, however the morphology and phylogeny of open-pollinated sweet corn cultivars has not been studied. Fifty eight open-pollinated sweet corn cultivars were characterized with thirty-four descriptors to provide information for breeders interested in broadening the genetic base of

The Efficiency and Effectiveness of Open Pollination in Musa Breeding

Asian Journal of Biochemistry, Genetics and Molecular Biology, 2019
Aims: This field experiment was conducted to determine if hand and open pollination methods affected performances of Musa progenies from 4x - 2x crosses and to identify promising progenies for recurrent selection. Study Design: The experimental design was a randomized complete block design with two replications of 6 plants per genotype.

Introgression in black poplar (Populus nigra L. ssp. nigra) and its transmission

Journal of Forest Science, 2002
: Introgression was studied in the offspring of P. nigra and P. × canadensis female trees using 3 enzymatic patterns (6-PGD, LAP and GPI). Our investigations were aimed at the offspring from open pollination and controlled pollination by the pollen ...

POLLINATION AND CYTOLOGICAL STUDIES ON THREE APRICOT (Prunus armeniaca L.) CULTIVARS. [PDF]

Journal of Plant Production, 2005
The present investigation was carried out during the two successive seasons of 2002 and 2003 on mature trees of Canino, Amal and Perfection three apricot cultivars. The pollination treatments used in this study were as follows:(1-)Open pollination.

Evidence of widespread pollen limitation in diverse specialty crops on commercial farms

Royal Society Open Science
Specialty crops (non-staple fruits and vegetables) have diverse pollination requirements and pollinator communities, yet production may be limited by pollen limitation.

Animal pollination shapes fruits market features, seeds functional traits and modulates their chemistry

Scientific Reports
In this study, we experimentally addressed the impact of different pollination treatments on the morphological, reproductive and chemical traits of fruits and seeds of two crop species, the wild strawberry (Fragaria vesca L.) and cowpea (Vigna ...

The effect of blow flies (Diptera: Calliphoridae) on the size and weight of mangos (Mangifera indica L.) [PDF]

PeerJ, 2016
Background: Pollination has a great effect on the yield of fruit trees. Blow flies are considered as an effective pollinator compared to hand pollination in fruit orchards.
