Seven types of Ocinuun, two from O. americanum, two from O. gratissimum, two
from O. sanctum and one from O. basilicum var. purpurascens, were studied for their
morphological differences, essential oil content and compositions. The oils were analyzed by GC
and GC/MS. All the types differ from one another in respect of their morphological characters as
well as their chemical constituents. Essential oil of the camphor type of O. americanum contains
camphor (40.3%) followed by limonene (8.8%) and oc-pinene (6.1%) as major constituents and
the citral type of O. americanum contains citral (63.4%) and linalool (7.0%) as major
components. The oil of O. gratissimum contains thymol (58.2%), y-terpinene (12.3%), p-cymene
(7.7%) and the var. clocimum of O. gratissimum contains eugenol (66.5%) and 0-ocimene
(18.1%) as major components. The major components of O. sanctum (green) are eugenol
(36.5%), P-caryophyllene (24.3%) and P-elememe (12.2%) and those of O. sanctum (purple) are
eugenol (77.5%) and (E)-caryophyllene (10.7%). The oil of O. basillicum var. purpurascens
contains linalool (30.8%), geraniol (28.8%) and geranyl acetate (14.1%) as major components.
Despite the increased recognition of the significance of market dynamics of homestead
forestry, research on the subject has remained strikingly limited. This research focuses on selected
aspects of marketing of homestead forestry products in two areas (Habilashdip and Chunati
Unions) in the district of Chittagong. The study mainly probes into principal actors in the market,
channel of marketing (for example grower-middlemen, middlemen-consumer etc.) the trends on
domestic consumption and sale of homestead agroforestry products, and the major problems (for
example absence of cooperative, poor storage facility, middlemen dependency) associated with
marketing. A number of measures for better marketing of homestead agroforestry products have
been suggested. The article ends with an exhortation for increased research on marketing of
homestead forestry.
Experimental planting with Aquilaria malaccensis Lamk. was undertaken to assess its
suitability on denuded hilly areas of Chittagong, Bangladesh. Germination of the species was 70
percent, and the seedlings attained a height of 40-60 cm in the nursery at the age of one year.
Average survival of the out-planted seedlings in four locations was 34.7 percent with 1.85m mean
height and 1.92 cm mean diameter after three years. Survival and seedling increment decreased
with increasing height of hill slope, apparently because of gradual low soil moisture content.
Strong and direct sunshine seemed to have adverse effect on seedling survival. The prospect of /I.
malaccensis appeared to be uncertain for the denuded areas. However, further investigation needs
to be undertaken.
