KAJIAN WARNA BUAH DAN UKURAN BENIH TERHADAP VIABILITAS BENIH KOPI ARABIKA (Coffea arabica L.) VARIETAS GAYO 1

ABSTRACT The purpose of this study was to examine seed viabilities of Arabica Coffee, variety Gayo 1 which was different in color of the fruits and in size of the seeds. The study was also aimed at examining interactions between fruit color and seed size on seed viabilities. Experiment was arranged in a randomized complete block design with three replications.  Factors studied were 1) fruit color consisted of three levels, namely, bright red, dark red, and yellowish green and 2) seed size consisted of large seeds, medium, small. Results showed that fruit color significantly affected germination rate, seedling growth rate, prompt germination, the time required to reach 50% germination (T50) and dry weight of normal seedlings. Seed size significantly affected germination rate, seedling growth rate, prompt germination, T50, and dry weight of normal seedlings. The best viability was found in the seeds derived from bright red fruits and small sized seeds

Nutmegg Seed (Myristica fragrans HOUTT) Viability Scarification on Several Levels and The Concentration of Young Coconut Water.ABSTRACT. One of the efforts to eliminate the mechanical barrier is by scarification treatment (scrubbing) the seed that becomes a thin shell that easily enter the water and air. Besides the presence of growth regulators in seed also be an important factor for accelerating the growth of seedlings. The experimental design used in this research in Completely randomized design (CRD) 3x3 factorial with three replications. There are two factors studied, namely scarification percentage and the concentration of young coconut water. Increased nutmeg seed viability and seedling vigor due scarification treatment , except for potential growth. Scarification 100% gives the acceleration of growth was significantly different from the seed without scarification but not significantly different from the scarification 50%. Concentration of 100% coconut water could also accelerate the growth of normal seeds without significantly as compared with young coconut water immersion, but not significantly different from the concentration or 50% young coconut water. There were no significant interaction between treatments were tested on the viability and vigor of seed germinating of nutmeg
