Pengaruh Kolkisin Terhadap Keragaman Genotip dan Fenotip Tanaman Aglaonema (Aglaonema cochinense Schott.) Varietas Lady Valentine

The Effect of Colchicine on The Genotypic and Phenotypic Diversity of The Aglaonema Plant (Aglaonema cochinense Schoot Var. Lady Valentine)

Abstract

The aim of the research was to determine the effect of colchicine on the genotypic and
phenotypic diversity of the Aglaonema plant. The research was conducted at the greenhouse
of Faculty of Agriculture, North Sumatera University Medan with 32 meters altitude, from
January 2017 to May 2017. The plant materials were immersed in 5 ppm and 10 ppm
colchicine for 3 and 6 hours. The result showed that the colchicine concentration significantly
affected the increased plant height. The plants were immersed in 10 ppm colhicine for 6
hours showed the morphological and chromosomal difference compared with the control and
other treatment.

Penelitian ini bertujuan untuk mengetahui pengaruh kolkhisin terhadap keragaman genotip dan fenotip tanaman aglaonema, Penelitian ini dilaksanakan di rumah kaca Fakultas Pertanian USU Medan, pada ketinggian ± 32 meter di atas permukaan laut dari bulan Januari sampai Mei 2017. Penelitian dilakukan dengan cara perendaman bahan tanam selama 3 jam dan 6 jam pada konsentrasi larutan kolkhisin 5 ppm dan 10 ppm. Hasil penelitian menunjukkan tanaman aglaonema hasil perlakuan berbagai konsentrasi kolkhisin berpengaruh nyata pada peubah amatan pertambahan tinggi tanaman. Hasil penelitian menunjukkan tanaman aglaonema hasil perlakuan perendaman selama 6 jam di dalam larutan kolkhisin 10 ppm memiliki karakter morfologis dan kromosom yang paling berbeda dibandingkan dengan kontrol dan perlakuan lainnya.
