Consequently, the farming of Conilon coffee has been conducted predominantly under irrigation because this condition enhances the production of flower buds (Carvalho, Colombo, Scalco, & Morais, 2006), increases the number of plagiotropic branches per plant (Nazareno et al.
TABLE 1 : Pearson correlation coefficient for the Absorbance of apical meristems of plagiotropic branches of young and adult plants of Araucaria angustifolia and monthly average temperature (minimum, average and maximum) and radiation, in 10 collection dates.
The seedlings were produced by rooting of apical cuttings of plagiotropic branches of cacao trees, of the PH 16 clone, with approximately 16 cm in length.
In orthotropic branching, the axes are upwardly inclined and the leaves are arranged around them in more or less radial symmetry, whereas in plagiotropic branching, planes of foliage are formed from leaves arranged along the sides of nearly horizontal twigs [14].
The following characteristics were assessed every three months to evaluate the effect of different irrigation regimes and planting densities on the vegetative growth of coffee plants: plant height (cm), using a graduated ruler and the number of primary plagiotropic branches of coffee plants.
This factor is commonly attributed to a reduction of plant storages in crop year with high yield, therefore, due to the lower growth of plagiotropic branches, the production in the following year is low (PEREIRA et al.
The rates of invasion and naturalization have been assigned to the combination of several ecological strategies (Klich, 2005): 1) the huge capacity for sexual reproduction, which secures the existence of a persistent seed bank (recently collected seeds showed 75% germination); 2) vegetative expansion that takes place from a gemmiferous, plagiotropic root system (physical fragmentation of the roots is translated into the release of bud dormancy, and new shoots appear over the soil surface); 3) its adaptive capacity is noticeable for achieving several allometric forms, a result of environmental heterogeneity; and 4) a variable root growth architecture that responds to different soil physical situations.

The upper third of the plant is where the largest number of plagiotropic branches producing coffee occur (Sandy et al.
For instance, on coffee trees, there are two types: orthotropic trunk and plagiotropic branches.
2]; it has monopodial, plagiotropic branching with five branches per node, giving it a tiered, open crown.
