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.

Unfertilized ovary pushes wheat flower open for cross-pollination [PDF]

Journal of Experimental Botany, 2017
Bread wheat is strongly autogamous; however, an opportunity for outcrossing occurs when self-pollination fails and florets open. The first phase of floret opening at anthesis is short and induced by lodicule turgidity. Some wheat florets re-open post-anthesis for several days, known as the 'second opening', for which the underlying mechanisms are ...

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

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 ...

Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

Advanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

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.

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.
