Bud take, growth and flowering were evaluated in Rosa indica [R.
chinensis] cultivars Odorata and Briar, R. macrophylla and R.
clinophylla budded with cultivars Super Star, Happiness, Eiffel Tower
and Kiss of Fire. Bud take at 2 weeks after budding was greatest for R.
indica cv. Odorata budded with Super Star (80%). R. macrophylla budded
with Eiffel Tower recorded the lowest number of days to sprouting
(21.33 days). R. indica cv. Odorata budded with Super Star produced the
tallest plants (37.67 cm) at 6 months after budding. However, at 15
months after budding, the tallest plants were obtained with R.
clinophylla budded with Kiss of Fire (119.67 cm) and R. indica cv.
Briar budded with Kiss of Fire (119.33 cm). At 6 months after budding,
the greatest plant spread was recorded for R. indica cv. Odorata budded
with Happiness (55.63 cm) and R. indica budded with Happiness (54.67
cm). Super Star budded on R. indicai> cv. Odorata produced vigorous
plants. At 15 months after budding, R. indica cv. Briar budded with
Happiness gave the longest flower stalk (5.43 cm). R. indica cv.
Odorata budded with Super Star recorded the greatest neck length (5.27
cm), number of flowers (24.04), and flower weight (146.00 g) and size
(6.83 cm). |
