Long-Term Effects of Deficit Irrigation and Subsequent Recovery of Young Japanese Plum Trees by Intrigliolo, Diego S., Castel, Juan R.

“…This was particularly effective when carried out together with lowering the crop load in order to alleviate the vegetative versus fruit growth competition. After two years of applying this strategy, the previously deficit irrigated trees were able to obtain a similar tree size than the control trees. …”

Influence of soil texture, climate and vegetation cover on secondary soil salinization in pampas plains, South America. by Milione, German, Mujica, Claudio, Dominguez Daguer, Diego, Bea, Sergio, Fernandez, María Elena, Gyenge, Javier

“…The lowest EC values were found in sites with sandy-textured soils and negative water balance, regardless of vegetation cover. When EC differences did occur between land uses of the same site (50% of the sites), in most cases – but not in all of them – the highest EC was measured under tree cover. …”

Variation in Vegetation and Ecosystem Carbon Stock Due to the Conversion of Disturbed Forest to Oil Palm Plantation in Peruvian Amazonia by Málaga Durán, N., Hergoualc'h, Kristell, Kapp, G., Martius, C.

“…Disturbed forests harbored species typical of primary forests, pioneer species and gaps opportunistic species. Their tree basal area (18.7 ± 1.4 m2 ha−1) and above-ground C stock (71.3 ± 4.2 Mg C ha−1) were, respectively, 50 and 60% of the values of undisturbed forests from the literature. …”

Vegetative propagation of patagonian cypress, a vulnerable species from the subantarctic forest of South America by Aparicio, Alejandro Gabriel, Pastorino, Mario Juan, Martinez Meier, Alejandro, Gallo, Leonardo Ariel

“…Increasing risks of loosing forest genetic resources and the need for a sustainable quality wood supply make focusing research efforts on undomesticated tree species necessary. The study of their genetic variation in vegetative propagation ability and the development of practical methodologies to obtain genetic copies are essential tools for conservation and breeding programs. patagonian cypress Austrocedrus chilensis is a vulnerable conifer native to the subantarctic forest of South America, with high ecological importance and economical potential. …”

Regeneration of threatened indigenous fruit species in Uganda, the case of Parinari curatellifolia by Mawula, Richard

“…They provide invaluable benefits to the entire biosphere: including but not limited to climate regulation in terms of rainfall cycle, oxygen supply and carbon sequestration, and provide fodder to both wild and domestic animal herds. The Mobola plum tree, Parinari curatellifolia Benth. is one such under-utilised species that serves as a key source of household income particularly in rural areas in Uganda. …”
