|Abstract: ||The investigation on “Studies on nursery and propagation techniques in polyembryonic
rootstocks of mango (Mangifera indica L.)” was carried out at the Indian Institute of
Horticultural Research, Hessaraghatta, Bangalore-89 during the period 2001-2002.
Fourteen polyembryonic varieties along with one monoembryonic Alphonso
studied for seedling attributes related to germination, growth and vigour. Earliest
germination was noticed in Muvandan and whereas the maximum germination percent
and rate of germination was in Muvandan and Olour respectively. With regard to seedling
growth characters like, seedling height, number of leaves and leaf area was maximum in
In osmopriming treatments, the variety Alphonso recorded the maximum seedling
height, girth, number of leaves and leaf area in treatment GA3 at 100 ppm concentration.
Bark and stem percent was maximum in varieties Vellaikolumban and Bappakai in
treatment GA3 at 100 ppm concentration.
In media and biofertilizer experiment, the seedling height, girth and number of
leaves were maximum in variety Alphonso and Muvandan in treatment comprising of
potting mixture (1:2:1 proportion) + cocopeat + VAM.
The bark inverted variety Olour recorded the minimum graft height and sprout
length whereas the seedling girth was maximum in variety Alphonso where bark
inversion was carried out.
Thus based on the different seedling growth and vigour characters, the
monoembryonic varieties Alphonso, Totapuri and polyembryonic varieties Muvandan,
Bappakai, E.C-95862 and Mylepelian were highly vigorous, where as Kurukkan,
Nekkare, Chandrakaran, Olour, Peach and Kensington varieties as vigorous and the
Kitchner, Starch, Prior and Vellaikolumban varieties could be placed under less vigorous
