Viable seeds / kg (approx.): 19,700

Minimum purchase: 100 g




Description



A. guachapele occurs naturally from Mexico through all of Central America to Ecuador,
and the Caribbean islands. It is a tree of medium to large size, relatively
fast growing, reaching 20 m and occasionally 25 m in height, with diameters (DBH) of 50 cm or more.



Uses



In Central America it is used mostly as a shade tree in pastures, and
for sawn wood with trees over 12 years of age. The wood is moderately durable,
hard and heavy, decorative, with a good finish. The sapwood is smooth and
whitish and the heartwood shows color bands, brown yellowish to brown. It is
used in rural construction for beams, boards, planks, floors, sleepers and
joinery.



Environmental
conditions



It is a pioneer species and very common in secondary dry forest, at
altitudes of 0-1200 masl, with annual rainfall of 600-1800 mm and mean temperatures
of 24-28ºC. Although it is a heliophytic species, it tolerates partial shade when
young.



Soils



It require fertile soils for an optimum development, but it can grow in infertile
and shallow soils. It does not tolerate frost or heavy soils with poor
drainage.



Seeds and nursery



As a pre-germination treatment, manual scarification is recommended,
using sandpaper until the seeds lose its natural shine and appear porous.
Alternatively, the seeds can be submerged in water at 70ºC for 4 minutes and then
leave them in running water at room temperature for 24 hours. A treatment that
gives very good results is making a small cut on the side opposite to the
embryo (e.g. with a nail clipper) followed by immersion in running water for 24
hours, but this is only practical for small batches. For the seedbed it is
recommended to use a loose substrate such as river sand, well washed and
disinfected. The seed should be distributed evenly or in rows separated by 2-3
cm, sowing superficially (2 mm). Germination occurs after 5-28 days. Seedlings
are very vigorous and transplanting can be carried out as soon as 3 days after
germination. The root is usually very long, so it must be pruned to about 3 cm
in length. When transplanting, be sure to make a hole deep enough in the substrate
to avoid curving up of the roots. Shade should be provided for the first 2-3
weeks after transplanting, for instance using shade clothing (saran) 50%. With
seeds of good germination it is possible to sow directly in containers, placing
2-3 seeds per hole, and then selecting the best seedling. The plants will be
ready for field planting after 3 - 4 months in the nursery or when they have a
height of 20-30 cm. A couple of weeks before planting out in the field it is
recommended to reduce watering to stimulate the lignification of the stems.



Growth



Typically,
trees in plantation grow on average 1-2 m/year in height and 1-2 cm/year in
DBH, during the first 10 years.
