The aim of this research was to study the mating system of a natural population of Theobroma grandiflorum (cupuassu) from Nova Ipixuna, Pará state, using microsatellite markers.
Regarding the two potential pollinators so far identified, the chrysomelid weevils may shelter in cupuassu flowers overnight, feed on pollen in the petal pouches, and then move on the following day when the flower wilts (Venturieri et al . 1997). Period of fruit ripening in cupuassu trees studied (based on 178 fruits in the first season and 162 fruits in the second season, all set by open pollination). Number of ovaries obtained in crossing between compatible and incompatible parental of cupuassu, at the floral season of 1995 and collected in three different times after pollination. HAP = hours Addison and Tavares (1951) described a cupuassu tree, which was self-compatible and allo-compatible, able to cross-pollinate other Theobroma species. Self-incompatibility is a common phenomenon in tropical species as an efficient system to avoid inbreeding (Bullock, 1985).

Insect Pollination Of The cacao flowers have structural characteristics that limit their pollination cacao and T. grandiflorum (cupuassu) are explored commercially on a large scale. commonly known as cupuaçu, also spelled cupuassu, cupuazú, cupu assu, Flowers of cupuaçu are structurally complex, and require pollination from biotic Black Beauty is a very well-adapted open-pollinated variety, thriving in almost Theobroma grandiflorum (cupuaçu, cupuassu, cupuazú, cupu assu, copoasu) within the same flower (self-pollination) or from one flower to important plants to make certain that pollination does cupuassu (Theobroma grandiflora). 13 mars 2021 — Cupuassu.jpg.

Rogério Gribel ASSESSMENT AND MANAGEMENT OF THE POLLINATORS OF MANGABA (Hancornia Cupuassu (Theobroma grandiflorum (Willd. ex Spreng.) Schumann) This species has a very low fecundity, attributed to problems with pollination and self-incompatibility, noted as being restrictive to the agronomic productivity of the species.

Its fruit is the national Carrying out the pollination - Pollination is done when the female flowers are receptive. Receptivity is manifested by the parting of the stigma and the simultaneous secretion of nectar. To verify this, the isolated inflorescence should be inspected daily or (depending on the skill of the pollinator) every other day, from the time of bagging to determine the precise date of receptivity. Pollination can be accomplished by cross-pollination or by self-pollination: Cross-pollination, also called allogamy , occurs when pollen is delivered from the stamen of one flower to the stigma of a flower on another plant of the same species.

hybridized (Alves et al., 2017) by using the cupuassu controlled-pollination technique, as reported by Venturieri & Ribeiro Filho (1995). After evaluating and selecting the progenies, the most productive parents, who remained asymptomatic for M. perniciosa after 15 years of field exposure, were duly identified and selected. #Pollination #FertilizationOur young ones can learn about the following by watching this short educative video:• Structure of a flower• Pollination• Fertiliz
Cupuassu (Theobroma grandiflorum) Pollination is carried out mainly by ants and aphids, with vespertine anthesis.

The Cupuassu is a plant native to the Amazon, found widely in the wild, when it can live to 80 years and reach more than 30m high. In the north, this vegetable is multiplied by grafting, budding or grafting and by seeds. Cupuassu (Theobroma grandiflorum [Willd. ex Spreng.] Schum.) is a plant that is native to the Amazon and of great importance to family farmers in northern Brazil (Alves et al.
However, attempts to increase the level of effective pollination are handicapped by low knowledge about the pollinators of cupuassu and their behavior.

Pollination is carried out mainly by ants and aphids, with vespertine anthesis. The fruit occurs in the form of a drupe and is strong and pleasant smelling. It is smooth on the outside, ellipsoidal, 25 cm long by 12 cm wide and weighs up to 1.5 kg. Approximately 300,000 plant species (almost 90 % of all flowering plants) require animal pollination to reproduce ). In addition, approximately 75 % of agricultural food crops have shown increased production as a result of animal pollination (Klein et al. 2007).Some studies have reported declines in pollinator species in different regions of the globe.
Flowers of cupuaçu are structurally complex, and require pollination from biotic vectors. The majority of cupuaçu trees are self-incompatible, which can result in decreased pollination levels, and consequently, a decrease in fruit yields. Pollination can also be negatively affected by environmental conditions. Physical Characteristics. Theobroma grandiflorum is an evergreen Tree growing to 10 m (32ft) by 10 m (32ft) at a medium rate. It is hardy to zone (UK) 10. The flowers are pollinated by Insects, Wind.
