| The
influence of 9 grades of mother planting material on the vegetative
growth, flowering, and multiplication of gladiolus (Gladiolus sp.) cv.
'Aarti' was studied. The largest size grade (>6.00 to <6.50 cm
diameter) produced significantly higher number of leaves per plant,
girth of scape, number of florets per spike, and weight and diameter of
corm. The greater height of plant, length of spike and rachis, and
number of flower spike per plant were produced by corm size of (>5.10
to <6.00 cm diameter). Number 1 (>3.80 to <5.10 cm diameter)
corm grade produced maximum diameter of second floret and number of
cormels per plant. Number 2 corm grade (>3.20 to <3.80 cm
diameter) produced higher number of cormels per plant and their
corresponding weight. One hundred percent of corms flowered up to No.3
grade, flowering percentage was reduced as corm size decreased. The
highest percentage of propagation coefficient was obtained with No. 6
grade corm. |
