Effect of Irrigation Intervals and Some Anti-transpirants on Productivity and Storability of Sweet pepper [PDF]

Journal of Plant Production
Water availability is one of the most important factors which limits vegetable crops productivity, so it is necessary to change/modify irrigation practice that enable plants to adapt/overcome the limited water.

Natural and artificial pollination of white-fleshed pitaya

Anais da Academia Brasileira de Ciências, 2022
To produce pitaya (Hylocereus spp.), it is essential that pollination occur, either artificially or by pollinating agents. This study evaluated the viability of self-pollination, cross-pollination, and natural pollination, as well as pollen viability ...

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 pollination in peach

International Journal of Horticultural Science, 1999
The peach is though considered to be a self fertile fruit species, also some self sterile and male sterile varieties have been registered. The latter type seems to be frequently met in Asian varieties, whereas in the USA and Europe, J. H.

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).

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 ...

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 ...

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.
