Abstract

ABSTRACTThis study aims to determine the effect of zeatin on shoot multiplication of explants nodesat Kulo and Puspita Nusantara varieties of chrysanthemum plant. Characters observerdwere time of shoots formation, number of shoot, number of leaf and number of root. Theresearch was conducted in the Laboratory of the Faculty of Agriculture, University ofSam Ratulangi for three month starting from July 2015 until October 2015.The researchwas designed using a completely randomized design with four treatments. Each treatmentwas repeated three time.Data was analyzed using variance analysis and Least SignificantDifference was used to differentiate the treatment. The result showed that the Zeatintreatment was significant difference on time of shoots formation, number of shoot andnumber of root at Kulo variety. Whereas, the Zeatin treatment was not significantdifference 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, numberof leaves, number of roots on Kulo and Puspita Nusantara variety. Application of 0,5 ppmZeatin concentration and control resulted the fastest of time of shoots formation on Kuloand Puspita Nusantara variety.

Abstract

ABSTRACTThe purpose of this study was to determine performance of the four rice varieties based on yield characters at Tincep village, Minahasa regency. The research was conducted in the Tincep Village, District of Sonder, Minahasa regency from June to October 2016. The experimental designed was used Randomized Block Design (RBD). The treatment were fout rice varieties namely Ciherang (P1), Mekongga (P2), Cigeulis (P3), and Suluttan Unsrat 2 (P4). Each treatment was replicated three times. The results showed that the treatment of the four varieties were not different base on observed characters viz weight of 1000 grain, harvest grain weight , number of unfilled grain, grain dry weight, and number of filled grain.Keywords : Varieties rice, yield characters, jajar legowo
