Continued Self-pollination in Cotton [PDF]
IN NATURE of Sept. 1, 1928, p. 314, Mr. G. L. Kottur distinguishes between “the deterioration of a selection due to selfing” and “the hybrid vigour of the F1 plants”. Surely, on whatever theory we interpret hybrid vigour, both phenomena are manifestations of it.

Self-fertility studies of some sweet cherry (Prunus avium L.) cultivars and selections
Fruit set of two sweet cherry cultivars (Alex' and 'Stella' ) and four Hungarian selections have been studied over two years following open pollination, unassisted self-pollination (autogamy) and artificial self-pollination (geitonogamy).

Self-pollination and expanding range [PDF]
Plant Biogeography![Figure][1] Species ranges are larger in plants that are able to self-pollinate than in those that must receive pollen from another individual, such as these dwarf monkey flowers in Oregon PHOTO: © DENNIS FRATES/ALAMY The mating system of a plant species may play an important role in determining its geographic range size ...

The role of late-acting self-incompatibility and early-acting inbreeding depression in governing female fertility in monkshood, Aconitum kusnezoffii. [PDF]
Reduced seed yields following self-pollination have repeatedly been observed, but the underlying mechanisms remain elusive when self-pollen tubes can readily grow into ovaries, because pre-, post-zygotic late-acting self-incompatibility (LSI), or early ...

We studied the mode of pollination in Greek oregano (Origanum vulgare ssp. hirtum) under both controlled and open pollination conditions. When grown indoors without the presence of insects, Greek oregano plants did not develop any seeds, indicating a low

Comparison of varying pollen source on productivity of sour cherry (Prunus cerasus L.) cultivars
Fruit set of five sour cherry cultivars (‘Újfehértói fürtös’, ‘Éva’, ‘Petri’, ‘Pándy 279‘ and ‘Csengôdi’) of eight years-old trees grown in Újfehértó, located in the Eastern north part of Hungary have been studied over two years (2008 & 2009).

Effects of open- and self-pollination treatments on genetic estimations in maize diallel experiment
This study investigated the effects of open- and self-pollination treatments on genetic estimations and kernel biochemical content in a maize diallel experiment. A 7×7 complete reciprocal diallel set (7 parents and 42 hybrids) was used as plant material.

In countries new to producing ‘Manzanillo’ olive trees (Olea europaea), free cross-pollination is often insufficient to obtain high levels of fruit set. An appropriate pollination design is therefore essential to ensure a timely, abundant, and compatible
