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 ...

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.

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.

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.

The genetic control of early growth properties in Pinus patula × Pinus tecunumanii hybrid families
Southern Forests: a Journal of Forest ScienceThe objective of this study was to determine the genetic control of growth properties in Pinus patula × Pinus tecunumanii hybrid families across seven sites planted in the summer rainfall region of southern Africa. Genetic material included in the analyses consisted of 61 families of P. patula × P. tecunumanii low elevation and 43 P.

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 ...

Dormacy Control in Pinus Patula Seed
South African Forestry Journal, 1981Trials to improve the rate of germination of Pinus patula are described. The trials show that either soaking the seed in a 200 g/l polyethylene glycol 6000 solution for 15 days or soaking for 24 ho...
