Intrinsic and extrinsic factors affecting pollination and fruit productivity in teak (Tectona grandis Linn.f.)

Published on

The intrinsic and extrinsic factors controlling pollination
and fruit productivity in teak (Tectona grandis Linn.f.)
have been studied in detail in Kerala, India. Though clonal
seed orchard establishment has progressed very well in
the country, low fruit productivity has hampered the teak
improvement programmes to a great extent. The field
studies as well as laboratory experiments led to the
conclusions that inadequate pollinator activity, low
pollen-ovule ratio, self-incompatibility and fruit abortion
due to dominance effect of floral and fungal infection are
the main causes for low fruit productivity in teak

Keywords: Teak, reproductive biology, fruiting potential, fruit abortion, self incompatibility, factors affecting fruiting, fruit productivity
