SEED TECHNOLOGY

The Seed Centre at Coimbatore is the first of its kind in India. It was established in 1975 and has been serving as the model Centre at State as well as at the National level.

Seed Technology has been standardized for following tree species:
Evergreen forests Dry deciduous forest Moist deciduous forest
Canarium strictum Gyrocarpus jaquinii Albizzia odorotissima
Vateria indica Chloroxylon swietenia Albizzia procera
Hopea parviflora Commiphora caudata Terminalia bellarica
Mesua ferea Holoptelia integrifolia ---
Bischofia javanica Emblica officinalis ---
Nephelium longana --- ---
Dysoxylon malabaricum --- ---
Semicarpus anacardium --- ---
Artocarpus hirsuta --- ---
Callophyllum elatum --- ---

standardization of propagation technology

Studies have been undertaken to evolve suitable propagation technology, using different soil mix and different concentrations of growth hormones such as IBA, IAA & NAA etc for the following species.

IMPACT OF BIO-NUTRIENT ON SEEDLINGS GROWTH and SEEDLINGS RAISED USING OPTIMUM BIO-FERTILIZERS
In Controlled conditions: Root system is not good.
In Treatment 4 condition: Root system is good.
