Continued Self-pollination in Cotton [PDF]

Nature, 1928
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.

Reusing Agricultural Wastewater for Tomato Production using Different Sources of Organic Fertilizer under the Conditions of the Delta Region [PDF]

Journal of Plant Production
The availability of fresh water (both in quantity and quality) is decreasing and becoming a major concern worldwide. The agricultural sector is the largest consumer of fresh water, so there is an urgent need to improve the agricultural practices to fill ...

Self-fertility studies of some sweet cherry (Prunus avium L.) cultivars and selections

International Journal of Horticultural Science, 2004
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).

The role of late-acting self-incompatibility and early-acting inbreeding depression in governing female fertility in monkshood, Aconitum kusnezoffii. [PDF]

PLoS ONE, 2012
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 ...

Self-pollination and expanding range [PDF]

Science, 2015
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 ...

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

Advanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

High cross-pollination rate of Greek oregano (O. vulgare ssp. hirtum) with Common oregano (O. vulgare ssp. vulgare) under open field conditions as revealed by microsatellite marker analysis

Biotechnology & Biotechnological Equipment, 2023
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

Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction

Advanced Science, EarlyView.
During floral induction, various environmental and endogenous signals converge to regulate the florigen protein, which is transported from leaves to the SAM to initiate flowering. Within the SAM, a complex network of receptor kinases and small peptides orchestrates floral development with high spatiotemporal precision.
