Interception by Pinus patula in relation to rainfall parameters
Journal of Hydrology, 1978Abstract Relationships between gross daily rainfall and interception and between rainfall duration and interception for four categories of rainfall intensity are given for a 10-year old stand of Pinus patula at Cathedral Peak in South Africa. Interception is shown to increase with rainfall intensity for given durations of a storm.

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.

Forest Ecology and Management, 1998
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.

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 ...

South African Forestry Journal, 1977
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.

Dominance in a Metric Trait of Pinus Patula Schiede and Deppe
Forest Science, 1987Abstract In an early Pinus patula Schiede & Deppe progeny test in Zimbabwe, three out of six full-sib families produced by controlled pollinations between ten plus tree parents showed statisitically significant 3:1 segregation ratios of large: small trees; a proportion of unusually large trees also occurred in the same families.

Towards a Protocol for the Micropropagation ofPinus patula
South African Forestry Journal, 1994SYNOPSIS In this investigation, different approaches to the micropropagation of P. patula were attempted and assessed in order to identify the most promising one for commercial application. Of the regenerative routes investigated, viz. axillary bud proliferation (dwarf shoot formation) from juvenile shoots, adventitious bud production and somatic ...
