Increasing viability of cinnamon [Cinnamomum burmanii L.] seed by soaking in rabbit urine

Abstract

Cinnamon is the main commodity of West Sumatra and Indonesia is the largest exporter of world markets. Cinnamon seeds are recalcitrant, so the fruit that has fallen out and is not fresh has experienced a decline in germination power. To improve the viability of cinnamon seeds, it is necessary to soak with rabbit urine. For this reason, a study was conducted to improve the quality of cinnamon seed viability through soaking in rabbit urine. This research was conducted at Balittro Laing Solok Experimental Garden from October 2017 to February 2018. The study used a completely randomized design [CRD] with 5 treatments namely rabbit urine dose: [1] without urine/water, [2] dose of 10 ml/l, [3] dose of 15 ml/l [4] dose of 20 ml/l [5] Dose of 25 ml/l, 30 seeds per box/plot and repeated 7 times. Seeds were used 7 days after harvest. Variables measured included: germination, vegetative growth of seeds [seed height, leaf number, leaf length, leaf width, stem diameter, number of roots, root length and biomass], chlorophyll analysis. The results showed that the seed germination was 60% while the vegetative growth of seed height, number of leaves, leaf length, leaf width, and stem diameter were found the best at doses 25 ml/l as well as for the variable root length, number of roots, whole wet weight, stem wet weight + leaves, root wet weight, whole dry weight, dry weight of stem + leaves, and dry weight of the root
