“…The main advantage for having self-rooted pecan cultivars is to speed propagation (1 versus 3 years), and most likely lower production costs of the propagated tree. In our knowledge, there is no literature showing selfrooted trees of pecan being more or less vulnerable to biotic or abiotic stresses (Casales et al, 2018;Garner, 2011;Renukdas et al, 2010) Early reports of pecan cultivars tissue culture include Smith (1977) but neither was successful in establishing plants in soil. Major issues in micropropagation of pecan have included poor rooting and poor survival after transplanting to the greenhouse (Brutsch et al, 1977).…”

Pecan, [Carya illinoinensis (Wangenheim) C. Koch] is a nut crop of growing worldwide interest and importance. In this research, a micropropagation protocol was developed during 2015-2016 using five pecan cultivars ('GraTex', 'Wichita', 'Choctaw', '10 J' and 'GraKing'). In the establishment phase, nodal segments of mature pecan trees were collected 9, 13, 17, 21, and 25 days after bud-break and maintained at 4°C for 0, 24, 48, or 72 hours. Next, they were soaked in 2.5% sodium hypochlorite for 1, 2, 3, 4, 5, 6, or 7 minutes. Each explant was cultured on DKW medium individually. For proliferation phase, the best established shoots were cut into nodal segments and cultured on DKW medium supplemented with different BA concentrations (4. 44, 13.30, 22.20, and 44.40 µM). Proliferating cultures were established and microshoots were rooted on MS medium containing IBA (4.9, 14.7, 24.5, and 49.0 µM) for 6 days in the dark. Date of cutting field-grown shoots for explanting had a significant effect on disinfection and culture establishment, with optimum success 11-15 days after bud break. Preliminary chilling treatment (4°C for 48 h) prior to cutting into nodal segments improved explant establishment. The best proliferation rate was obtained using 22.2 µM BA. Root induction using 24.5 µM IBA gave the highest rooting percentage. Rooted microshoots were successfully transferred to pots. Although the 'Wichita' and '10 J' cultivars had the highest success for acclimatization (89% and 84% respectively) the difference between cultivars was not significant and plantlets of five pecan cultivars were successfully acclimated. The results of this research can be applied by the authors in commercial level.

“…The data found in the present study show the possibility of pecan propagation by the rescue of propagating material from adult plants and the application of IBA. Although pecan is a species that presents poor rooting of cuttings (Casales et al, 2018), a greater uniformity is obtained when plants Figure 4.

The objective of this work was to evaluate the effect of the collection period and of the exogenous application of indolebutyric acid (IBA) on the rooting of cuttings from adult pecan (Carya illinoinensis) plants. The experiment was carried out in a greenhouse with intermittent mist irrigation, from December 2017 to October 2018. The experimental design was completely randomized, in a 4x5 factorial arrangement, with four collection periods (spring, summer, autumn, and winter) and five concentrations of IBA (0, 2,000, 4,000, 6,000, and 8,000 mg L-1). For the cuttings collected during summer and autumn, there was a linear relationship between rooting and the increase of the IBA concentration. The best results for rooting, callus formation, mean number of roots, mean root length, and root dry and fresh mass are obtained for the cuttings collected during summer, with the application of 8,000 mg L-1 IBA on the base of each cutting, under a mist irrigation system. The rooting of cuttings from adult pecan plants with the application of IBA is possible, being an alternative propagation method for the species.

“…Deste modo, temperaturas baixas reduzem a atividade metabólica de sementes e diminuem a produção de giberelina que consiste em um hormônio essencial para o processo de germinação e formação de plântulas. Os hormônios endógenos possuem grande importância na mobilização das reservas de lipídios que possuem papel fundamental no fornecimento da energia necessária para desencadear o processo de germinação (CASALES et al, 2018). Conforme Nakagawa (2000), temperaturas inferiores e superiores à temperatura ótima para germinação também tendem a expor as sementes a condições adversas para o processo de germinação, deste modo afetando a porcentagem de germinação destas.…”

O objetivo do presente trabalho foi avaliar o efeito da luminosidade e temperatura na germinação de sementes de Carya illinoinensis (Wangenh) K. Koch. Para uniformizar o processo de embebição, as sementes foram previamente submetidas ao processo de escarificação mecânica. O delineamento experimental foi inteiramente casualizado, arranjado com esquema fatorial 3x4, no qual foram testados três regimes de luminosidade (ausência de luz, luz contínua e luz alternada de 12 horas) e quatro condições de temperatura (20°C, 25°C, 30°C e alternada de 12 horas a 15°C e 12 horas a 25°C), com cinco repetições. Variáveis avaliadas foram emissão de radícula (%), o índice de velocidade de germinação (IVG), o tempo médio de germinação (TMG), as plântulas normais (%), as plântulas anormais (%), as sementes duras (%), as sementes mortas (%), o comprimento de raiz e da parte aérea (mm/plântula). A combinação de ausência de luz e temperatura elevada favorece a emissão da radícula e o IVG, e reduz TMG, assim como proporciona maior comprimento de raízes e parte aérea. Entretanto, a temperatura de 25°C em conjunto com ausência de luz obteve resultado superior para formação de plântulas normais, sendo essa combinação mais indicada para a germinação de sementes de C. illinoinensis.
