Abstract:
Influence of seed orientation and depth of sowing on germination, seedling emergence and seedling vigour
in Anjan (Hardwickia binata Roxb) was investigated. The seeds collected from 20- year old trees were sown
in sand filled earthen pots at 1.5,3.0 and 5.0 cm depths, adopting three orientations of the embryo viz., up
right (embryo facing up), horizontal and inverted positions. The experiment was laid out in a completely
randomized design. Percentage germination, root and shoot length and dry matter production were
measured and the vigour index was calculated. Placing the seeds with the embryo in a horizontal or inverted
position at a depth of 1.5 cm and 3.0 cm resulted in early and higher germination, higher root and shoot
length, greater dry matter production and vigour index.
