Abstract
An experiment was conducted on biologically active substances in aqueous
extracts of leaves of some herbal plants viz.,Ashok (Saracaasoca), Basok
(Justicaadhatoda),Arjun (Terminaliaarjuna),Bohera_ (TerminaliabelericaRoxb.),
Neem (Azadiractaindica),Bel (Aeglemarmelos),andfor each field crop seeds
such as, Rice (Oryzasativa) and Jute (Corcoruscapsulars), with the attempt for
chemical investigation on effective plant extract. The aqueous extract of Bohera
significantly increased and enhanced germination, growth of shoot length and
root length of Rice and Jute seeds compared with control whereasArjune, Beal,
Neem, Asok and Basok reduced and delayed germination, growth of shoot
length and root length of these same crops.). A significant variation was
observed among the treatment in respect of different parameters of rice
and jute. In pot experiment, highest germination index in rice was found with
extract of bohera (15.71) and in petridish experiment highest germination
percentage was observed with the aqueous extract of bohera (97%). While In
pot experiment, lowest germination index in rice was found with water (11.41)
and in petridish experiment lowest germination percentage was observed with
the aqueous extract of arjune (94%).In pot experiment, highest shoot length in
rice was found with extract of bohera (77.57 cm) and in petridish experiment
highest shoot length was observed with the aqueous extract of arjune (6.56 cm).
While In pot experiment, lowest shoot length in rice was found with water
(62.04 cm) and in petridish experiment lowest shoot length in rice was found
with extract of ashok (5.78 cm). In pot experiment, highest root length was
observed with the aqueous extract of bohera(29.83 cm) and in petridish
experiment highest root length was observed with the aqueous extract of bashok
(5.70 cm). While In pot experiment, lowest root length in rice was found with
water (20.10 cm) and in petridish experiment lowest root length in rice was
observed with the aqueous extract of arjune (4.56 cm). On the other hand,In pot
Description
There are different types of plants such as, fruit trees, herbal plants or medicinal
plants, woody plants, ornamental plants, necrotic crops, herbaceous plants, shrubs,
weeds etc. in plant kingdom. The plant kingdom supplies us with food, fuel, fodder,
shelter, wind breaker and provide raw materials for clothing and medicine. Some
plants supplies us carbohydrates, protein and fat which are the major sources of
energy. Different types of mineral substances such as, calcium, magnesium, iron,
cobalt, chlorine, potassium, manganese, molybdenum, zinc, sulfur, nitrogen,
phosphorus etc. which are obtained from some plants like vegetables, fruits etc. which
are essential for human and also for animal life.
