Plants in the C22 cycle were 50 cm taller had twice the leaf area index, reached anthesis 7 days later and had a 30% higher harvest index than C0 (Table 1) [clarification needed] Differences in growth were detected early in ontogeny. The root growth of C22 exceeded that of C0 and the ratio of shoot dry mass to root dry mass was reduced by ...
Trees that are cross-pollinated or pollinated via an insect pollinator produce more fruit than trees with flowers that just self-pollinate. [1] In fruit trees, bees are an essential part of the pollination process for the formation of fruit. [2] Pollination of fruit trees around the world has been highly studied for hundreds of years.

Branch of a Rainier cherry tree. Rainier (/ r eɪ ˈ n ɪər / ray-NEER) is a cultivar of cherry. It was developed in 1952 at Washington State University by Harold Fogle, and named after Mount Rainier. It is a cross between the Bing and Van cultivars. [1] Rainiers are considered a premium type of cherry. They are sweet with a thin skin and ...
Alternatives to hybridization include open pollination and clonal propagation. [2] An important factor is the heterosis that results from the genetic differences between the parents, which can produce higher yield and faster growth rate. Crossing any particular pair of inbred strains may or may not result in superior offspring.
A site tree, is a single tree in a stand (group of growing trees) that gives a good representation of the average dominant or co-dominant tree in the stand. Site trees are used to calculate the site index of the site in reference to a particular tree species. A site tree should belong to the dominant or co-dominant overstory class. [1]
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 ...
The different rates of maturity between the stamens and the pistil ensure cross pollination. There are six fleshy nectar glands at the base of each sepal which attract pollinators. Each fertilized flower matures into a large (1 cm) deep-blue berry-like fruit which houses two bitter seeds. The large seeds are covered with a characteristic blue ...
A pollination network is a bipartite mutualistic network in which plants and pollinators are the nodes, and the pollination interactions form the links between these nodes. [1]
