PENGARUH ZEATIN TERHADAP MULTIPLIKASI TUNAS EKSPLAN NODUS PADA TANAMAN KRISAN VARIETAS KULO DAN PUSPITA NUSANTARA

Abstract

ABSTRACT
This study aims to determine the effect of zeatin on shoot multiplication of explants nodes
at Kulo and Puspita Nusantara varieties of chrysanthemum plant. Characters observerd
were time of shoots formation, number of shoot, number of leaf and number of root. The
research was conducted in the Laboratory of the Faculty of Agriculture, University of
Sam Ratulangi for three month starting from July 2015 until October 2015.The research
was designed using a completely randomized design with four treatments. Each treatment
was repeated three time.Data was analyzed using variance analysis and Least Significant
Difference was used to differentiate the treatment. The result showed that the Zeatin
treatment was significant difference on time of shoots formation, number of shoot and
number of root at Kulo variety. Whereas, the Zeatin treatment was not significant
difference on number of shoot and number of leaf at Puspita Nusantara variety.
Application of 0,5 ppm Zeatin concentration result the highest number of shoots, number
of leaves, number of roots on Kulo and Puspita Nusantara variety. Application of 0,5 ppm
Zeatin concentration and control resulted the fastest of time of shoots formation on Kulo
and Puspita Nusantara variety.
