Growth of Various Chrysanthemum (Chrysanthemum morifolium R.) Cultivars Cuttings on Different Auxin Type

Abstract

This study aims to obtain qualified seedlings, and speed up the rooting of some varieties of
chrysanthemum (Chrysanthemum morifolium R.) cuttings use synthetic and naturally plant growth
regulator (auxin). Research results are expected to be an alternative method of application effective
and environmentally friendly plant growth regulator. The research was conducted from March to
April 2013 at the Research Institute of Ornamental Plants (Balai Penelitian Tanaman Hias). The
experimental design used is completely randomized design (CRD) factorial. The first factor is the
type of auxin which consists of four levels ie control, indole acetic acid (IAA), naphthalene acetic
acid (NAA), pregnant cow urine, and not pregnant cow urine. The second factor is the type of
chrysanthemum varieties which consists of four levels ie spray type of Puspita Pelangi, spray type
of Puspita Nusantara, standard type of Sakuntala, and standard type of Pasopati. The results
showed that type of chrysanthemum cultivars and type of auxin not affected the percentage of live
cuttings, percentage of rooted cuttings and percentage of sprouted cuttings. The cuttings root of
plant that given by pregnant cow urine is better than other treatments. Cuttings root length, and
number of primary root of Pasopati is better than other cultivars. The interaction influence between
the type of auxin and chrysanthemum cultivars found only in the number of secondary roots,
diameter of root and length of the shoot cuttings at 12 DAP.
