Abstract:
Seeds collected from identified Candidate plus trees of Tecomella undulata from six districts
(Jalore, Pali, Sikar, Churu, Bikaner and Nagaur) of Rajasthan were evaluated for seed size,
germination percentage, mean daily germination, peak value, germination value, germination
rate, seedling growth and shoot vigour index at nursery stage. Considerable variations were
recorded for seed germination among the progenies of identified CPTs which ranged from 27.50
% to 92.0%. Maximum germination percent of 92% was recorded for CPT-35 of Pali districts
owing to higher mean daily germination (4.6) and peak value of germination (11.42) with higher
germination rate (15.35) and germination value (52.53) whereas with respect to seedling height
and shoot vigour index, CPT-4 from Nagaur districts performed better in comparison to other.
The results of the present study identified progenies of two CPT's i.e. CPT-35 (Pali) and CPT-4
(Nagaur) as superior which performed better in seed germination and seedling growth attributes
at nursery stage. Seed germination for three distinct morphotypes (Yellow, Orange and Red) of
Tecomella undulata was also recorded and it was observed that seeds collected from yellow
colored flower shows higher seed germination. |
