This paper deals with the iron status of different species of banana
leaves ; the effect of application of sulphur in sail on iron mobilization
and the effect of injection of iron salt solution on iron absorption by
banana leaves.
IRON STATUS OF BANANA LEAVES AND
RESPONSE OF SULPHUR APPLICATION
ON IRON UPTAKE1

Soil and leaf samples were collected from the groves of five edible
banana species grown in a green house, SoiI around the selected
banana plants was treated with sulphur both in the plots and in pots
aop’ying 100, 200 and 300 kg of sulphur per hectare. Two ml of
FeSO4 solution (5000 ppm) was injected on tha pseudosten at tha
base of tha third ycungest leaf. After four weeks, scil and leaf
samples were collected for analysis. Sunflower seedlings grown under
similar sulphur treated conditions were collected efter 20 days.
It was revealed from the results of the analytical data that iron
content in banana leaves vary from one species to the other. But
most of the species selected for this work contained higher amount
of iron in leaves compared to the iron content of sunflower seedlings.
The injection of FeSO4 solution in the pseudostems of iron deficient
banana plants gave expedited response in iron absorption by leaves
compared to the application of sulphur in soil which was done for
increasing the mobilization of iron.

Teak has occupied a dominant
position in the plantation programme of
Bangladesh. As much as 70-80 percent
of the total plantations established in
the hill forests is composed of Teak
(Douglas 1981, White 1979). In the future
plantation programmes also it is likely to
remain to be the principal species.
The rate of return from Teak plantation
is not known in Bangladesh. Because
of lack of this information it is not possible
to compare Teak with other promising
species and without doing so forestry

Among pole species in Bangladesh
Sundri is the most favoured one because
of its very good strength properties and
abundant availability. These facts have
prompted the Bangladesh Power
Development Board and the Bangladesh
Rural Electrification Board to show a keen
interest in using Sundri poles in power
transmission line in Bangladesh.
Sundri pole comes of a stem of Sundri
which occurs as a small to medium sized
evergreen tree with a grooved and buttressed

characteristic pneumatophores,
gregariously in the deltaic
of Bangladesh where it occurs
throughout the tidal forests. It is estimated
that the Sundarban forests could provide
more than 50,000 Sundri poles annually in
perpetual yield. (Latif 1965 ).

Oil palm (Elaeis guineeiisis Jacq.) is
indigenous to West Africa (Zeven 1965,
Hartley 1967) where it grows wild in a
320-480 km coastal belt from Gambia to
Angola (Moe and Mohtadi 1971) E. guineensis
var. tennera, with thinner shelled fruits,
is a hybrid of ‘dura’- a wild variety with
thicker shell and ‘piscifera’ with no shell
(Rahman et al 1979). It is an exotic high
oil yielding fruit crop from Malaysia and
introduced in Bangladesh in 1978-79 with
a view to developing the domestic nonconventional
source of vegetable oil to
meet the demand of both edible and industrial
oils of the country. As such, Bangladesh
Forest Department initiated raising 4047
ha of oil palm plantation in the high
rainfall regions like Chittagong, Chittagong
Hill Tracts, Cox’s Bazar and Sylhct Forest

Since long past offset and rhizome
planting have been conventional methods
of small scale bamboo propagation in the
villages of Bangladesh and other
neighbouring countries (Peal 1882). Use of
these propagules, however, is not economic
for large scale bamboo afforestation
programme due to their bulky size, heavy
weight (4-30 Kg) and transportation
problem (Banik 1980). Moreover, a clump
can supply these propagules in only limited
numbers, certainly not enough for large
scale plantation. The availability of bamboo
seeds is also restricted because of long
flowering interval in bamboo. Propagation
of bamboo through branch cutting

Necessities of investigators with diverse
interests in fungi have led to the formulation
of new, and modifications of existing
media to buit the specific need of the
researchers during the past. Thus, 185 fungal
culture media have been listed by Booth
(1971). T..ao (1970) has reviewed a large
number of selective media and stressed the
increasing need for evolving more and more

selective media. Most of the selective
media so far evolved have dealt with the
isolation of fungi from soil. Only a very
small number of media deal with the isolation
of fungi from infected plant parts.
Rahman (1982) reported Sclerophoma
pythiophila (Cda.) Hohn to be the most
common associates of Ramichloridium pini
de Hoog and Rahman. During isolation

The main economic aspects of the family Ve benaceae in relation
to the major categories of uses such as timber, medicine, food,
fodder, ornamental, insecticide, dye and live fences in Bangladesh
have been reviewed. Other passible uses have also been noted.
The medicinal uses are grouped disease wise. A checklist of Bangladesh
species with the indication of their economic uses has been appended.
