“…(Tetsumura et al 2001), e na castanheira-da-índia, Castanea sativa Mill. (Vieitez et al 1980). Portanto a origem das raízes adventícias pode ser dos calos, do parênquima do floema, do câmbio ou ainda, segundo Hartmann et al (2002), do tecido jovem do floema secundário ou dos raios vasculares.…”

RESUMO -(Capacidade de enraizamento de estacas de quatro cultivares de Vitis L. (Vitaceae) relacionada com os aspectos anatômicos). A estaquia é o método de propagação vegetativa mais utilizado e apresenta como ponto crítico o início do desenvolvimento de um sistema radicular funcional. A estrutura anatômica da estaca pode interferir no processo de enraizamento de algumas espécies, todavia em videira não há informações a respeito. O objetivo deste trabalho foi avaliar a capacidade de enraizamento de estacas de cultivares de Vitis, com ênfase aos aspectos anatômicos. Os quatro cultivares estudados foram: Vitis labrusca L. cv. Bordô, V. rotundifolia Michx. cv. Topsail e os porta-enxertos híbridos entre V. berlandieri Planch. × V. riparia Michx., 'Kobber 5BB' e 'SO4'. Destes cultivares apenas 'Topsail' apresentou dificuldade de enraizamento. Após 77 dias do plantio das estacas, foi observada uma baixa capacidade de enraizamento do cv. Topsail em relação aos outros três cultivares analisados. Também observou-se uma alta porcentagem de estacas vivas, porém não enraizadas, e a ausência de calos neste cultivar. Esses dados podem indicar a existência de fatores endógenos do cv. Topsail que dificultam o enraizamento das estacas. As características anatômicas da base das estacas do cv. Topsail diferiram das demais por manter as calotas de fibras no floema primário, pela presença de floema secundário reduzido com faixas radiais de fibras. Desse modo, a dificuldade de enraizamento desse cultivar pode estar relacionada a barreiras anatômicas.

Cutting is the most common method of vegetative propagation. A critical step in this process is the initial development of a functional root system. The anatomical structure of the cutting has been shown to affect the rooting ability of some species, but for grapevines this has not yet been investigated. The aim of this work was to evaluate the rooting ability of Vitis cuttings, with emphasis on the anatomical aspects. The four cultivars studied were: Vitis labrusca L. cv. Bordô, V. rotundifolia Michx. cv. Topsail and hybrid rootstocks of V. berlandieri Planch. × V. riparia Michx., 'Kobber 5BB' and 'SO4'. Of these cultivars, only 'Topsail' showed poor rooting ability; 77 days after planting the cuttings, poor rooting ability of cv. Topsail was observed in relation to the other three cultivars. A high percentage of live cuttings was observed, but they did not take root. There were no calluses on this cultivar. These data may indicate the presence of endogenous factors in cv. Topsail that make it difficult for cuttings to take root. The anatomical features of the base of the cv. Topsail cutting were different from those of the other cultivars in that they retained the fiber bundles of the primary phloem, and they also had reduced secondary phloem with radial fiber bands. Therefore, rooting difficulty in this cultivar may be related to...

“…For instance, placing woody cuttings in water led to rapid root development for some species (McNight & Biesterfeldt 1968; Hansen & Phipps 1983; Phipps et al 1983); consequently, root primordia developed to a stage where functional roots emerged shortly after transplanting. In addition, a successful adventitious root establishment requires establishment of a vascular link between the carbohydrate source and the newly developed root that is also related to the anatomical characteristics of the cutting (Vieitez et al 1980; Friend et al 1994). Thus, formation of new roots close to the existing vascular tissue is an important factor.…”

The use of willow cuttings for streambank stabilization is a common practice in riparian ecosystems throughout the United States. Many environmental factors govern the outcome of such planting. However, other factors such as preplanting treatments, planting methods, and physiological status of cuttings (dormant vs. actively growing) may also be crucial in determining the survival of willow cuttings. Actively growing (nondormant) Black willow (Salix nigra) cuttings, 30 cm in length and 1 cm in diameter at the base, were subjected to three soaking treatments (0, 7, and 15 days) prior to planting. Following the initial treatment, cuttings were grown in a greenhouse in pots under three soil moisture regimes (well-watered but not flooded, permanently flooded, and intermittently flooded). Plant gas exchange, growth, biomass, and survival were measured. Results demonstrated that soaking for 7 days was beneficial to early development of cuttings in the well-watered (control) soil moisture regime, enhancing percent bud flush and survival significantly. However, 15 days of soaking proved to be detrimental to survival of cuttings irrespective of soil moisture regimes. Results also demonstrated that the beneficial effects of 7-day soaking were limited to the well-watered soil moisture regime but not to the flooded or intermittently flooded regimes. Soaking nondormant cuttings may be worthwhile if the planting site is likely to present ample soil moisture but nonflooded conditions to the transplanted cuttings.

“…As reservas orgânicas e, principalmente o amido, constituem um fator importante para o desenvolvimento de raízes adventicias (CHEFFINS e HOWARD, 1982), pois o amido quando presente na estaca constitui-se a única fonte de carboidratos que irá prover a energia necessária para a iniciação e o desenvolvimento de primórdios radiculares (VIEITZ et al, 1980). O teor de triptofano encontrado nas estacas de kiwi, diminuiu significativamente, durante o processo de enraizamento, sendo alto antes dos tratamentos e, bastante reduzido após os tratamentos.…”
