Cosecha Estocástica Óptima de Rodales de Pino Radiata
El efecto de la aleatoriedad de los precios y del inventario de rodales es muy significativo. En el caso de la aplicación a una empresa forestal, aumenta el corte óptimo actual en un en un 66,9 % y el óptimo determinístico en un 93,3%. Ambas volatilidades son igualmente importantes, para valores inferiores al 50% prima la volatilidad de los precios y superiores la del inventario de rodales. Un ...
متن کاملSummary We characterized a Pinus radiata D
We characterized a Pinus radiata D. Don putative ortholog to the Arabidopsis thaliana (L.) Heynh. SHORT-ROOT gene (AtSHR) and analyzed its expression in different organs during vegetative development and in response to exogenous auxin during adventitious rooting. The predicted protein sequence contained domains characteristic of the GRAS protein family and showed a strong similarity to the SHOR...
متن کاملPyrolysis Products of Pinus Radiata Bark
The yields of char, tar, and non-condensible gases from the pyrolysis of Pinus radiata D. Don bark were measured. Pyrolysis of bark, on a small preparative scale using an airacetylene flame, gave 48% char with ash content 3.5% (mainly aluminium, calcium, potassium, and silica), and recovered tar in 7% yield (on oven-dried bark equivalent). The major components of the pyrolysis tar were catechol...
متن کاملThe Abortion of Conelets in Pinus Radiata
Observations and records collected over a six-year period show that, in a seed orchard of Pinus radiata at Kaingaroa Forest, approximately half of all female strobili initiated abort during the first year after pollination. For an average clone this process of conelet drop starts at the time of receptivity, reaches a peak some four to six weeks later, and then decreases in intensity. This time ...
متن کاملModeling productivity and transpiration of Pinus radiata: climatic effects.
Climatic effects on annual net carbon gain, stem biomass and annual transpiration were simulated for Pinus radiata D. Don at Canberra and Mt. Gambier. Simulations were conducted with an existing process-based forest growth model (BIOMASS, Model 1) and with a modified version of the BIOMASS model (Model 2) in which response functions for carbon assimilation and leaf conductance were replaced wit...
