Floral biology in relation to hand pollination of white yam
Euphytica, 1983Flowering behaviour and the morphology of flowers in white yam,Dioscorea rotundata Poir. is described in relation to hand pollination. Plants flowered between June and September with flowering intensity depending largely on factors associated with shoot vigour in genotypes.

Using the finger nails to remove most of the petals is a fast method of preparing apple flowers for hand pollination in the balloon stage. Such flowers still appeared quite attractive to insects; left to open pollination, the seed set per flower averaged two thirds of that of similarly treated, but hand-pollinated flowers.

A classroom exercise in hand pollination and in vitro asymbiotic orchid seed germination
Plant Cell, Tissue and Organ Culture, 2008While many scientific reports on orchid seed germination provide germination protocols, few provide concise descriptions of plant selection, hand pollination, and asymbiotic seed culture for use in classroom exercises. Another major limitation for conducting orchid seed germination exercises is the availability of seeds or flowers to pollinate. In this

Euphytica, 1988
Controlled hand pollinated pistils of rubber were observed using fluorescence microscopy to assess the efficiency of the universally-employed method for the production of progeny for plant breeding. The controlled hand pollination method conducted in the morning resulted in the deposition of a mean of 15.6 pollen grains on the stigma, with no stray ...

Journal of Visualized Experiments, 2020
The Japanese plum cultivars commonly grown are interspecific hybrids derived from crosses between the original Prunus salicina with other Prunus species. Most hybrids exhibit gametophytic self-incompatibility, which is controlled by a single and highly polymorphic S-locus that contains multiple alleles. Most cultivated hybrids are self-incompatible and

Hand-Pollination ofCardamine californicaImproves Seed Set
Native Plants Journal, 2006Hand-pollinating milkmaids (Cardamine californica (Nutt.) Greene var. integrifolia (Nutt.) Rollins [Brassi-caceae]) increased seed set from 8% to 85%. In the Presidio of San Francisco, a district of the Golden Gate National Recreation Area in California, our restoration efforts using milkmaids were hampered by low seed set of our locally adapted plants.

Asymbiotic seed germination of hand-pollinated terrestrial orchids
Acta Horticulturae, 2017Orchids are known for their adaptation to different environmental and biotic factors, especially pollinators and mycorrhizal fungi. Association with symbiotic fungi has a crucial impact on orchid growth and metabolism, from germination through the seedling stage and in many cases throughout their life.

Unlikely transmission of Cowpea aphid-borne mosaic virus by hand pollination of passionflower
Tropical Plant Pathology, 2021Passion fruit plants are self-incompatible and fruiting is exclusively dependent on cross-pollination, which in nature is performed by carpenter (mamangava) bees, especially Xylocopa spp. (family Apidae). To ensure satisfactory productivity, daily manual pollination is a common practice among passionflower growers.

Pollen viability is known to decline, sometimes rapidly, with age and exposure to environmental stresses. Because of the potential impact of nongenetic factors on the ability of pollen to fertilize ovules, researchers conducting hand‐pollinations should attempt to control the freshness or viability of pollen used.
