Growth models forPinus patulain Angola
Southern Forests: a Journal of Forest Science, 2010This study developed growth models for Pinus patula Schiede ex Schltdl. et Cham. for the Central Highlands of Angola for simulating the development of stand characteristics. The model set included dominant height, individual-tree diameter increment, individual-tree height and self-thinning models.

Plantlet Production from Somatic Embryos of Pinus patula
Journal of Plant Physiology, 1995Summary Embryogenic tissue was induced from embryonic explants of Pinus patula , using intact female gametophytes containing immature embryos. Cone collections were carried out during the summer months from December to March and various parameters such as embryo length and the presence of cleavage and cotyledonary embryos were examined in ...

Abstract Pinus patula accounts for about 26% of all forest plantations in Kenya and is used mainly for timber, pulpwood and plywood production, whereas Pinus patula subspecies tecunumanii and Pinus oocarpa have been planted on experimental scale only. The three close coned pines were studied in a field trial planted in 1985 at Turbo, Kenya as part of

Cryopreservation and plant regeneration from somatic embryos of Pinus patula
Plant Cell Reports, 2000Embryogenic tissue of Pinus patula Scheide et Deppe was cryopreserved for 8 weeks using sorbitol and dimethylsulfoxide (DMSO) as cryoprotectants. Results indicate that 0.3 M sorbitol and 5% DMSO had the best cryoprotecting effect. The recovered tissue initially underwent a lag phase but then continued to proliferate normally on MSG3 maintenance medium.

Performance of twoPinus patulahybrids in southern Africa
Southern Forests: a Journal of Forest Science, 2012Two Pinus patula hybrids, P. greggii × P. patula and P. patula × P. tecunumanii, were planted across a number of sites in southern Africa. The growth and survival for each species/taxon was assessed at either 5 or 8 years of age at each site and compared to the respective parental species.

Burning Branch wood under Pinus patula
South African Forestry Journal, 1977SUMMARY Branches, tops and other woody material left after pruning and thinning operations can safely be burnt under the standing trees. Provided the soil and lower humus layer are thoroughly moist and the correct procedure is followed there should not be any damage to trees which have been pruned to 5 or 7 metres.

ABSTRACT Three experiments on the raising of Pinus patula nursery stock are described. Seed was sown at depths of 1,6; 3,2 and 6,4 mm and either mulched with a polythene sheet or not. The mulch, together with a sowing depth of 3,2 mm gave the highest germination at 14 and 28 days.

Salicylic Acid Increases the Biomass Accumulation of Pinus patula
Southern Journal of Applied Forestry, 2003Abstract Aqueous solutions of low concentrations of salicylic acid (SA), applied as a spray to the shoots of 3-month-oldPinus patula Schiede ex Schltdl. & Cham seedlings, significantly increased the biomass of the plants. The measurements were taken after nine monthly treatments.
