Growth—

Pinus jaliscana grows in a subtropical to tropical climate, with a mean annual temperature of 22 - 26°c, a 5 - 6 month dry season and a mean annual precipitation ranging from 1,000 - 1,935mm[2, 3]. Pine species in general require a sunny position if they are to grow well and, whilst the different species have their own soil preferences, most will thrive in a light well-drained sandy or gravelly loam[4, 5]. Seed cones are 45 - 98mm long and 30 - 60mm wide when open. The cones take two growing seasons to mature, ripen in winter and can hang on the tree for several years without opening[2]. The tree is adapted to survive and even thrive in regions liable to fire. It has a thick bark that helps to insulate it from the heat of low-intensity fires; it readily casts its lower limbs so that there is less material available to burn, and it has serotinous seed cones that can remain closed on the tree for several years until stimulated to open by the heat of a high-intensity forest fire[2]. A strongly fire-dependent species, regenerating prolifically after fires that expose mineral soils, but on poorer sites it is readily outcompeted by other pine species that grow in the area[2]. Plants in this genus are notably susceptible to honey fungus[6].

Propagation

Seed - germination normally takes 15 - 20 days, and the germination rate of fresh seeds is usually 80 - 95%. The presence of mycorrhizae is highly beneficial for survival and early growth, so it is recommended to inoculate with spores or to add soil from near established trees. Seedlings can be planted out 4 - 8 months after germination, when they are about 30cm tall[7]. The seeds can be stored for years under dry, cold and airtight conditions[7].
