Haldu (Adina cordifolia Roxb. Hook. f. ex Brandis) is
large deciduous tree species of family Rubiaceae. It is one of
the common associate species in West gangetic moist mixed
deciduous forests and on well-drained deep soil in Shivalik.
It also occurs in dry region of Ceylon and sub-Himalayan
tracts from Nepal Eastward to Asom. In Western Himalayas,
it is confined to outer slope up to 1000 m. The tree occurs
scattered in the deciduous forests throughout India, with
exception of arid region of Rajasthan (Mandal et al. 1984).
The wood of the species is used for making doors and
window frames, plywood. The species is also heavily
exploited for fuelwood and fodder. Natural regeneration of
the species is very difficult as the minute seeds (about 11
million seeds/kg) as well as young seedlings in forests are
washed away very easily and thus survival and establishment
in forests is very less. The species therefore requires
immediate attention for its regeneration, cultivation and
conservation (Kaushal et al. 2010). Exact knowledge of
maturity time is therefore essential to avoid the collection of
immature and non-viable seeds which can cause nursery and
plantation failure. The present study was therefore conducted
to develop seed maturation indices for better regeneration
and multiplication of the Adina cordifolia.
Fruits of haldu were collected from Tanda (29°02 N,
079°23 E and 242.42 m amsl) and Lalkuan (29°04 N, 079°30
E and 230.2 m amsl) forests of tarai and Bhakara (29°10 N,
079°25 E and 287.87 m amsl) and Barheni (29°14 N, 079°17
E and 318.18 m amsl) forests of bhabar region.
Fruits were collected starting from first week of April
and continued every seven days until the fruits were not
available. For collecting the fruits, five healthy average sized
trees were selected on phenotypic basis. After collection, the
fruits were brought at field laboratory of Agroforestry
Research Centre (AFRC) of G B Pant University of
Agriculture and Technology, Pantnagar, Uttarakhand (29° N,
79°.3 E and 243.84 m amsl) during April–May 2010. The
fruits were dried in sunlight till opening. Fruit colour, moisture
content per cent and specific gravity was recorded during
each collection dates at all the collection sites as per standard
procedure (ISTA 1993). The germination study was conducted
in germinator which was maintained at 25±2ºC temperature.
The data were statistically analyzed using two way ANOVA
(Snedecor and Cochran 1967) to find out the presence of
significant difference between sites and dates. The analysis
was carried out with the Statistical Package for Social Sciences
(SPSS) windows software package.
