There is a possibility that the time of submersion in natural rooting, with respect to vegetative propagation by fig cuttings, may have a significant effect or differences in the formation and characteristics of the roots. For this reason, the research was carried out in the Multipurpose Nursery, belonging to the Cota Cota Experimental Centre, under a completely randomised design with factorial arrangement, using a mother plant of more than 12 years old, which is an indication that propagation would be difficult, due to the characteristics of the plant material. The response variables evaluated were: days to root formation, percentage of survival, root length, number of roots, and percentage of lodging. The following results were obtained based on the averages of the data collected in the field research: T9 (lentil water, 48 hours) rooted in 54 days, being the best rooting time. The percentage of survival was influenced by the rooting factor directly, with the natural rooters of lentil water and willow infusion responding much better, with 85.70 and 83.66 % respectively. The rooting and submersion time presented a direct significance in root length, which is equal to 7.60 cm, with treatment 5 (willow infusion, 24 hours). In the variable number of roots, both lentil water and willow infusion achieved 8 and 7 root units respectively, both in a submersion time of 24 hours, and it is also important to note the significance in both factors. Treatment 9 (lentil water, 48 hours) with 90 % was the best average in the variable percent rooting. It was confirmed that the longer the soaking time, the more positive the rooting of the cuttings, depending on the rooting agent used. [ABSTRACT FROM AUTHOR]

In Argentina, the cultivation of Robinia pseudoacacia is uncommon, and there are few studies on its behavior in forest plantations. Forestry research in the Alto Valle has been mainly oriented to the commercial cultivation of "poplars" and "willows" (Salicaceae) and there are not any records on the cultivation of R. pseudoacacia. Due to the lack of information on the cultivation of this species in the region, this review aims to integrate different botanical and ecological aspects of R. pseudoacacia to evaluate its feasibility as a silvicultural alternative in the Alto Valle de Río Negro. A bibliographical review of botanical and ecological aspects of the species was carried out, as well as local field studies. Information on the nomenclature, taxonomy, distribution, habitat, and ecology of the species is included. Robinia pseudoacacia presents plasticity and is adapted to the agro-ecological conditions of the region, so its cultivation is feasible. We expect to describe, in future contributions, aspects of the forestry-productive type that complement this review. [ABSTRACT FROM AUTHOR]

In Argentina, energy production depends mostly on fossil fuels; hence it is desirable to diversify the energy sources including renewable fuels such as forest biomass. A drawback for this development is the lack of information about the productivity of short rotation coppice systems (SRC) under local conditions. Willows are used in several countries as a source of biomass for energy, although in Argentina the information about yield at local level is scarce. An SRC system was established in agricultural soil in Buenos Aires Province, Argentina. The aim of this work was to estimate the effects of irrigation, plantation density and genotype on biomass production. The clones used were the hybrid Salix matsudana x Salix alba 'Barrett 13-44 INTA' and the open pollinated Salix alba 'Yaguareté INTA - CIEF'. There were no statistically significant effects of clone and plantation density on biomass productivity. The only significant factor was irrigation, which explained 83 to 92 % of yield variability. The dry biomass yields are similar to those reported elsewhere for rainfed SRC willows, ranging between 11.1 and 22.6 Mg ha-1 year-1. [ABSTRACT FROM AUTHOR]

The threat caused by the spread of exotic elmleaf blackberry (Rubus ulmifolius (Schott)) in Reserva Natural Municipal Laguna de los Padres (RNMLP), prompted the study of carabld assemblages associated with native wood remnants of Colletia paradoxa ((Spreng.) Escal.), Celtis ehrenbergiana (Klotzsch) Liebm. and Salix humboldtiana (Willd) that still persist. We found that species richness was higher in the wood of S. humboldtiana (DE), followed by that of C. paradoxa (BC) and C. ehrenbergiana with two different anthropic uses (Talar with recreational use (TR) and Talar anthropized (TA). BC and DE, located within the protected and conservation zone, taken together, accounted for more than 85% (53 species) of the total specific richness surveyed, while TR and TA, both located outside the protected zone, contributed with 56% (35 species). Carabid assemblages differed internally throughout the seasons, and also among them in species composition and dominance. The most abundant species was Argutoridius bonariensis (Dejean) which dominated in TA and TR assemblages during all seasons. DE and BC revealed their own set of species, including an endemism for the first. Predators were the most abundant trophic guild for all sites. The conservation status and possible natural or artificial factors that determine the diversity of carabids found for each forest was discussed. [ABSTRACT FROM AUTHOR]

This work revises the genus Salix in the province of Mendoza in order to contribute to the knowledge of its phanerogamic flora. Seven species, one subspecies, one variety, two forms and thre hybrids are recognized. Among them there is one native species and one native variety. Each taxon is identified through one key, described, documented and illustrated. [ABSTRACT FROM AUTHOR]
