The 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 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 کاملImprovement of non-key traits in radiata pine breeding programme when long-term economic importance is uncertain
Diameter at breast height (DBH), wood density (DEN) and predicted modulus of elasticity (PME) are considered as 'key traits' (KT) in the improvement in radiata pine breeding programmes in New Zealand. Any other traits which are also of interest to radiata pine breeders and forest growers are called 'non-key traits' (NKTs). External resin bleeding (ERB), internal checking (IC), number of heartwo...
متن کاملEvaluation of the strength of shaved steamed Pinus radiata poles
Bending strength of Pinus radiata (D.Don) poles is critical in a range of structural applications, such as retaining-walls. Pinus radiata poles in a wet, shaved and steamed condition were obtained from five suppliers located across the central North Island of New Zealand. This sample of poles met the stiffness (Modulus of Elasticity) value expected of normaldensity poles according to New Zealan...
