Dovyalis

For the commercial cultivation of dovyalis, it is necessary a homogeneous and uniform orchard, with the use of seedlings with phytosanitary quality.

However, there is little information in literature regarding the dovyalis agronomic behavior (Alves, 2014).

The dovyalis plants originated from seeds of fruits harvested in a loca orchard after two years of cultivation, germinated in polystyrene trays containing the HortMax[R] commercial substrate and transplanted when reached 20 cm in height to 14 polypropylene pots, containing as substrate argisso + fine washed sand (1: 2 ratio , v/v).

The cuttings were collected using gloves, as the dovyalis plants have many thick thorns.

For experiment II, 540 woody cuttings were collected from the middle part of the dovyalis plants, being divided into 3 groups according to size (10, 15 and 20 cm), and the number of leaves/cutting: 2, 4 and 6 leaves.

For the experiment III, 300 cuttings of the middle position of the dovyalis plants, with 15 cm in length and containing 4 leaves, were distributed in four different substrates, being 1 coconut fiber + Plantmax commercial substrate + Vermiculite of medium texture, 2 - latoso + medium texture vermiculite + washed fine sand, both in the proportion of 1: 1: 1, v/v/v), 3 - latosol + sand and 4 - latoso + vermiculite (the last two in the 1:1 proportion, v/v).

It was possible to observe a significant interaction for the average number of shoots and average number of roots on dovyalis cuttings (Figures 1 and 2).

There was a significant interaction between IBA concentration and cuttings types for the average number of shoots, only in cuttings of dovyalis from the middle part of the matrix, with the best results observed using IBA 1250 mg [L.sup.-1], according to the equation obtained by the statistica data.

Figure 2 shows a significant interaction for root number in dovyalis cuttings.

2006) and in dovyalis, Dovyalis hebecarpa (Almeida et al., 2007).

Table 1 shows the average root length (cm) and shoot fresh biomass (mg) of dovyalis cuttings, according to the region where the cuttings were taken in the branch of the matrix plant.

For dovyalis, a trend can be observed in tissues with a high C/N ratio (basa and middle cuttings) due to the higher amounts and better quality of emitted roots, corroborating with Paiva and Gomes (2005).

In Table 2 is possible to observe the significant interaction for cuttings length and number of leaves of dovyalis cuttings according to the number of buds.
