Abstract
The present investigation entitled “Standardization of portion of plant part
used and IBA concentration on commercial production of ZZ plant (Zamioculcas
zamiifolia) (Lodd.) Engl.’’ was conducted at College of Horticulture, Mojerla in the
year 2017-18. The experiment consists of four different concentrations of IBA (0,
1000 ppm, 1500 ppm and 2000 ppm) and seven different portion of plant parts
(entire pinnate leaf, two leaflets with a node and stalk, only stalk (with no leaflet),
leaflet with a node and stalk, leaflet with no node and stalk, apical half of leaflet,
basal half of leaflet) were used. The plant portions were dipped in IBA for one
hour. The experiment was laid out in Factorial Completely Randomized Design
with two replications.
Portion of plant part were planted in polybags containing two parts of red
soil, one part of coco peat and one part of Vermicompost.
Among the plant growth regulators, IBA 1000 ppm recorded minimum
(30.5) days to rhizome initiation, maximum number (3.3) of rhizomes, diameter of
rhizomes (3.8 cm), fresh weight of rhizomes (32.7 g), moist content of rhizomes
(74.0 %), number of roots (12.5), length of roots (13.5cm), number of days taken
for leaf stalk emergence (85.1), length of leaf stalk (16.2 cm), number of leafstalks
(1.9), number of leaflets on leaf stalk (6.2), length of leaflet (8.1 cm), width of
leaflet (3.8 cm), minimum number of days taken for finishing of pot plant (202.2).
Among portion of plant part significantly better results were obtained in
entire pinnate leaf (except in number of days to rhizome initiation (48.5)).
Maximum number of rhizomes (6.1), diameter of rhizomes (6.1 cm), fresh weight
of rhizomes (83.9 g), moist content of rhizomes (87.7 %), number of roots (23.1),
length of roots (17.0 cm), number of days taken for leaf stalk emergence (92.0),
length of leaf stalk (41.1 cm), number of leaf stalks (2.5), number of leaflets (9.6)
on leaf stalk, length of leaflet (10.2 cm), width of leaflet (4.7 cm), minimum
number of days taken for finishing of pot plant (220.1). Whereas only stalk (no
leaflet) did not form callus and rhizome formation also not observed.
The interaction between portion of plant part and plant growth regulator IBA
significantly influenced almost all parameters. Entire pinnate leaf with IBA 1000
ppm registered better results (except in minimum days to rhizome initiation, it was
recorded minimum in two leaflets with a node and stalk has taken (29.0) days to
rhizome initiation), maximum number of rhizomes (7.5), diameter of rhizomes (9.0
cm), fresh weight of rhizomes (156.3 g), moist content of rhizomes (89.7%), number
of roots (30.0), length of roots (19.2 cm), number of days taken for leaf stalk
emergence (86.5), length of leaf stalk (52.2 cm), number of leaf stalks (3.5) per
plant, number of leaflets (13.0) on leaf stalk, length of leaflet (11.6 cm), width of
leaflet (5.4 cm), minimum number of days taken for finishing of pot plant (208.0).
