Plant species where normal mode of seed set is through a high degree of cross-pollination have characteristic reproductive features and population structure. Existence of self-sterility, [1] self-incompatibility, imperfect flowers, and mechanical obstructions make the plant dependent upon foreign pollen for normal seed set. Each plant receives ...
The MN55 cultivar apple developed by David Bedford, a senior researcher and research pomologist at the University of Minnesota's apple-breeding program, and James Luby, PhD, professor, Department of Horticultural Sciences, Horticultural Research Center, is a cross between Honeycrisp and MonArk (AA44), a non-patented apple variety grown in Arkansas.
As a result of the Honeycrisp apple's growing popularity, the government of Nova Scotia, Canada, spent over C$1.5 million funding a five-year Honeycrisp Orchard Renewal Program from 2005 to 2010 to subsidize apple producers to replace older trees (mainly McIntosh) with newer higher-return varieties of apples: the Honeycrisp, Gala, and Ambrosia.

Cross-pollination involves the transfer of pollen grains from the flower of one plant to the stigma of the flower of another plant. The main characteristics which facilitate cross-pollination are: Herkogamy : Flowers possess some mechanical barrier on their stigmatic surface to avoid self-pollination, e.g. presence of gynostegium and pollinia ...

This leads to shifts in pollination syndromes and to some genera having a high diversity of pollination syndromes among species, suggesting that pollinators are a primary selective force driving diversity and speciation. [5] [6] Ophrys apifera is an orchid species that has a highly evolved plant-pollinator relationship. This specific species ...
Meet the Patagonian Mara.. You can find these small rodents grazing the plains of South Argentina. While their limbs are perfect for running, their hoof-like claws are great for digging up burrows
