| dc.description.abstract | Increasing productivity in cultivation of okra plants
(Abelmochus esculentus L. Moench) can be done by mutation to produce
populations that have diversity. This research was conducted to determine the
effect of colchicine concentration on phenotypic changes in okra varieties
(Abelmochus esculentus L. Moench) resulting in plants with polyploidy. This
research was carried out on research fields at the Faculty of Agriculture,
University of North Sumatra and at the Biology Laboratory, Faculty of
Mathematics and Natural Sciences, University of North Sumatra from March to
June 2023. This research used a Randomized Block Design (RAK) with 2
treatment factors. The first factor is the Zahira IPB Variety and the Naila IPB
Variety. The second factor is administering colchicine doses of 0%, 0.20%,
0.40%, and 0.60%. The results showed that the Zahira IPB variety was
significantly different from the Naila IPB variety regarding plant height at 5-13
WAP, number of leaves at 6-13 WAP, fruit length, fruit diameter, number of fruit
per plant, and fruit weight per plant. Giving colchicine concentration had a
significant effect on plant height at 2-13 WAP, number of leaves at 4-9 WAP, fruit
length, fruit weight, and number of fruit. The interaction between varieties and the
provision of colxin concentration had a significant effect on okra plant height at
11-13 WAP, and the number of leaves at 8 WAP. | en_US |
