“…The seedlings of the cultivars lasted six months by cloning. This experiment used stem cuttings measuring 5-6 cm, containing one node and a pair of leaves, collected from the median region of branches from stock plants grown in a clonal garden close to the nursery, according to Ambrozim et al (2017), with adaptations. The cuttings were immersed in a fungicide solution (87.5% thiophanate-methyl) at the dose of 0.8 mL•L -1 for 5 minutes and treated according to Secundino et al (2018), with 4,000 mg•kg -1 of the growth regulator indolebutyric acid, in powder.…”

Fusarium is the main disease of black pepper (Piper nigrum L.) in Brazil, and grafting using resistant rootstocks can be a sustainable management strategy. Several wild Piper species have been considered resistant to infection. However, further studies on the grafting process are needed to generate a safe technical recommendation for farmers. This research was carried out with the objective of evaluating the initial compatibility of grafting through the interaction between two techniques (top cleft and side cleft) and six rootstocks.The P. nigrum 'Bragantina' was grafted onto four wild Piper species (Piper aduncum Link, Piper tuberculatum Jacq., Piper marginatum Jacq., and Piper hispidum Kunth) and two black pepper cultivars ('Kottanadan Broto Branco' and 'Bragantina'-homograft). P. tuberculatum and P. marginatum were incompatible with P. nigrum 'Bragantina' in the two grafting techniques. There was total suppression of leaf development with incompatible rootstocks inside cleft grafting. The wild rootstocks had twice as many shoots at the base of the seedling than the cultivars in the top cleft grafting. Side cleft grafting was able to suppress by half the shoots at the base of the rootstock, while the aerial part was maintained. Top cleft grafting provided greater survival, shooting, and leaf emission, which was more evident when using P. aduncum species as rootstock, reaching practically twice the shooting (59.3%) in comparison with the side grafting (30.6%). Therefore, the top method and the use of P. aduncum as rootstock for the production of grafted black pepper seedlings is recommended.

The production of black pepper seedlings through grafting is a promising strategy to mitigate the effect of environmental stresses, such as drought, that limit its cultivation. However, studies on compatibility between grafts and rootstocks are still scarce, especially considering the wild species of the genus Piper and the cultivated genotypes of black pepper. The objective of this work was to evaluate the relationship between primary metabolism and the development of black pepper seedlings obtained through intra- and interspecific grafting. The method used was that of cleft lateral grafting, as graft the Bragantina cultivar, better known in the world as ‘Panniyur 1’, and ‘Kottanadan’ cultivar and three wild species (Piper hispidum, Piper aduncum and Piper tuberculatum) were used as root-stock. As a control, ´Bragantina` was grafted onto itself (homograft). The experiment was carried out for 110 days and the seedlings were evaluated for development, gas exchange, and carbohydrate allocation. The rootstock influences the development and primary metabolism of seedlings. P. aduncum showed greater initial compatibility among wild species, due to less impediment to carbohydrate flow. P. tuberculatum showed early incompatibility, as the grafts died. The seedlings grafted on P. hispidum and 'Kottanadan' had initial compatibility with an average of 78% survival and 60% budding, but they may have late incompatibility due to limitation of carbohydrate flow.
