O objetivo deste trabalho foi determinar alterações fisiológicas e de tolerância à seca em clones de café Conilon ( contrastantes quanto à sensibilidade ao deficit hídrico. Foram avaliadas as enxertias recíprocas entre os clones 109A, sensível ao deficit hídrico, e 120, tolerante 120/109A, 120/120, 109A/120, 109A/109A ?, além de seus respectivos pés-francos. As plantas foram cultivadas em vasos de 12 L em casa de vegetação. Após seis meses, metade das plantas foi submetida ao deficit hídrico por meio da suspensão da irrigação, até que as folhas atingissem o potencial hídrico de antemanhã de -3,0 MPa. Quando o clone 120 foi usado como porta-enxerto, as plantas apresentaram sistema radicular mais profundo, mas com menor massa, retardaram por mais tempo a desidratação celular das folhas e apresentaram maior eficiência no uso da água. Sob seca severa, os teores de amido e sacarose decresceram em todos os tratamentos, enquanto os teores de glicose, frutose, aminoácidos totais e prolina aumentaram, particularmente nos tratamentos 109A pé-franco, 109A/109A e 120/109A. Essas plantas apresentaram menor eficiência no uso da água. O acúmulo de solutos não foi associado à tolerância à seca. O uso de porta-enxertos tolerantes à seca contribui para a maior tolerância das plantas ao deficit hídrico.
The objective of this work was to determine alterations in physiology and those due to drought tolerance on Conilon coffee (Coffea canephora) contrasting clones regarding the sensitivity to hydric stress. The reciprocal grafting between clones 109A, drought sensitive, and 120, drought tolerant, ? 120/109A, 120/120, 109A/120, 109A/109A ? along with their ungrafted control plants (109A and 120) were evaluated. Plants were cultivated in 12‑L vases in greenhouse. Six months after grafting, half of the plants was subjected to water deficit, by suspending irrigation until leaves reached the hydric potential of ‑3,0 MPa. When clone 120 was used as rootstock, plants presented deeper roots, although with lower root‑biomass, higher ability to postpone leaf dehydration and higher instantaneous water‑use efficiency (WUE). Under severe drought, starch and sucrose contents decreased similarly, regardless of the treatment, whereas leaf concentrations of glucose, fructose, total amino acids and proline were higher in non‑grafted 109A, 109A/109A, and 120/109A plants. These plants showed the lowest WUE values. Solute accumulation was not primarily related to drought tolerance. The use of drought tolerant rootstocks improves to drought tolerance in coffee.

The plants of C. arabica do not naturally produce a large number of orthotropic sprouts, hindering clonal multiplication by cutting, which would be the simplest technique with a lower cost of production compared to other methods of vegetative propagation. An alternative form, used successfully in the propagation of eucalyptus, is propagation by minicutting, which consists of pruning the shoot apex of the plant, forming the ministumps, which in variable time interval emits the shoots that will be used to make minicutting. In C. arabica plants the number of shoots can be increased with the application of growth regulators and fertilizers. So, the purpose of this work was to verify the effect of growth regulators and foliar fertilizers on the emission and development of orthotropic shoots of C. arabica. The experiment was installed in a randomized complete block design, with ten treatments composed by growth regulators and fertilizers: T1 (Control); T2 (Stimulate + Sturdy + Enervig); T3 (Stimulate + Vitakelp + Biozyme); T4 (Tiba + Sturdy + Enervig); T5 (Tiba + Vitakelp + Biozyme); T6 (Brs + Sturdy + Enervig) T7 (Brs + Vitakelp + Biozyme); T8 (Stimulate); T9 (TIBA); T10 (Brs-Brassinoesteroid), each plot consisting of two plants. Biometric and physiological parameters were evaluated for the ministumps, as well as the biometric parameters of the shoots and plant survival. The results showed that there was no influence of the treatments on the biometric parameters of the ministumps. A greater number of orthotopic sprouts were obtained in treatments with the TIBA growth regulator, as well as a greater plant survival of the minicuttings, after 25 days of transplanting in a greenhouse. It was concluded that TIBA treatments influenced the production and quality of clonal minicuttings of C. arabica.
