| O marmeleiro pertence à família Rosaceae. Atualmente, tem sido utilizado como porta-enxerto de pereira devido sua característica ananizante. O floroglucinol é um composto fenólico, potencializador da auxina. O presente trabalho foi conduzido em telado com nebulização intermitente e teve como objetivo avaliar a capacidade de enraizamento de estacas lenhosas de marmeleiro, tratadas com floroglucinol (zero, 1500 e 3000 mg.L-1), para indução de raízes. As cultivares testadas foram Pineapple, Meliform, Alongado, Radaelli, Portugal, Inta e MC. As estacas foram preparadas com 12 cm e ½ folha na parte superior, acondicionadas em caixas plásticas contendo vermiculita média. O delineamento utilizado foi o de blocos ao acaso, em arranjo fatorial (3 x 7), com 3... |

| ABSTRACT The state of Rio Grande do Sul is the largest peach productor in Brazil; however, it still possesses poor yield values when compared with other states. One of the problems associated with this is the occurrence of soils with drainage problems, mainly in Pelotas region, which depending on the year period, may undergo water deficit or flooding situations in the great majority of the years, which harm the crop development and yield. Among the harmful effects caused by these stresses stand out, the decrease in the net assimilation rate, closure of stomata, reduction of the cell activities, production of reactive oxygen species, membrane and protein destabilization. Thus, the aim of this study was to investigate in what magnitude of the gaseous... |

| ABSTRACT Nursery trees of stone fruits (Prunus spp.) are traditionally produced by union of two distinct genotypes - the rootstock and the scion - which, by grafting, form a composite plant that will be maintained throughout of all plant life. In Brazil, the rootstocks are predominantly seed propagated and therefore usually results in heterogeneous trees for vigor and edaphic adaptation. However, with advances in rootstock breeding programs that released cultivars and certification in several countries (notably in Europe), the system will come gradually evolving for vegetative propagation (cuttings and tissue culture) and use of seeds of selected rootstocks with specific characteristics and potted nursery trees production. For scion cultivar propagation,... |
