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.

Cupuassu pollination

[1] Native and common throughout the Amazon basin, it is naturally cultivated in the jungles of Colombia, Bolivia and Peru and in the north of Brazil, with the largest production in Pará, Amazonas and Amapá. [1] Pollination by insects, wind, or other agents transfers pollen to an ovule. Pollinator gets nectar and accidentally transfers pollen.

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. 2007).

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. 2007). In general, cupuassu plantations have low productivity due to the unselected planting material employed, with high

Cupuassu seeds are recalcitrant (Velho et al. 1990), and seed dispersion is thought to be performed by The site of self-incompatibility action in cupuassu ( Theobroma grandiflorum )1 ALESSANDRA R. RAMOS 2 , GIORGINI A. VENTURIERI 3,6 , SILVIA M. CUCO 4 and NEUZA M. CASTRO 5 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. Controlled pollinations between compatible and incompatible parents were made and flowers were collected at three times: 24, 48 and 72 h after pollinations, during the floral seasons of 1995 and 1998. A Many Neotropical tree species occur at a considerably similar situation might occur in cupuassu under natural lower density than temperate equivalents, with agglomera- conditions, with the mixture of compatible and incompat- tion of individuals, which tends to reduce intrapopulation ible pollen allowing self-pollination and/or crossing be- genetic diversity due to small effective population Cupuassu flowers are hermaphrodite, but present extremely efficient anatomical barriers to avoid direct access of pollen grains from anthers to the stigma. Silva (1996) observed that 100% of spontaneous self-fertilization was avoided based onlyonhercogamy,andconcludedthatT.grandiflorumdid not present agamospermy requiring pollination for pod set. However, attempts to increase the level of effective pollination are handicapped by low knowledge about the pollinators of cupuassu and their behavior.
Cupuaçu (Theobroma grandiflorum) é uma espécie nativa da Amazônia que vem sendo plantada comercialmente no Brasil para satisfazer a demanda pelo seu suco, de sabor marcante, obtido da polpa que envolve as suas sementes. 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.

Self Pollination. In this process, the pollen grains transfer from the stigma of the same or genetically similar flower. Self-pollination can be observed in legumes such as orchids, sunflowers, peas, peanuts, oats, peaches, potatoes, wheat, and others.
