Title

Effect of Storage Treatment on Small White Ginger Rhizome Viability Melati Melati; Devi Rusmin

One problem for developing small white ginger (Zingiber officinale var. amarum) is theavailability of high quality rhizome seeds in right quantity and time. Seed rhizome will sproutquickly, and its quality will decreased in immature seed rhizome and in not good storage conditions.The main objective of the experiment was to study the best storage room conditions for storagerhizome seeds of small white ginger. The experiment was conducted in seed laboratory and storageroom of Research Institute for Medicinal and Aromatic Crops Bogor. The experiment wasconducted by randomized complete design with nine different storage, 3 replication and 25 sampleseach treatment. The treatments are 1) rhizome seeds storage in room temperature (control),(2)rhizome seeds storage in AC room (16–240C),(3) rhizome seed soaked in paclobutrazol 1000 ppmfor 4 hours then seeds storage in room temperature ( 4) put rhizome seeds in rack and cover bystraw, storage in room temperature (5) rhizome seed storage on straws in the greenhouse ( 6)rhizome seed storage in the greenhouse without straw ( 7) rhizome seed soaked in water during 1hour every month then dried naturally in 300C and storage in AC room (8) rhizome seed soakedin paclobutrazol 1000 ppm for 4 hour then storage in AC room ( 9) put rhizome in wood box andcover by rice straw and husk. Variables observed include moisture contents of ginger seed, lostweight of seed and germination percentage of rhizome seeds at the end of storage period. The resultof experiment indicated that the moisture content and weight rhizome seeds decrease after 2 months. After four months storage period, moisture content was still high above 80 %, exceptrhizome seeds in under ground. The rhizome seeds that store in AC room showed the bestperformance and thus, this treatment can be recommended for storage of small white gingerrhizome seeds for 4 months. The low moisture content (< 80%) of rhizome small white ginger seedswill decreased its viability.Keywords: Zingiber officinale var. amarum, seed, storage, viability

The experiment was conducted at Gunung Putri Experimental Station and PlantPhysiology Laboratory of Indonesian Medicinal and Aromatic Crops Research Institute(IMACRI), from November 2008 to July 2009. The aim of the experiment was to determinephysiological maturity of Pimpinella pruatjan seed and to study its morphological structures.Observation and sampling using one hundred plants with four replications. Results of theexperiment showed that the physiological seed maturity on the first and third umbell of P.Pruatjan was achieved at 7 weeks after anthesis, and physiological seed maturity on thesecond umbell was achieved at 8 weeks after anthesis. Seed dry weight on the physiologicalseed maturity on first, second and third umbells were 166,87; 158,20, and 141,35 mg/100pericarp, respectively. Germination percentage and germination speed on the first, secondand third umbells were 5,75 % and 0,22 %/etmal; 22,75 % and 0,94 %/etmal; 10,50 % and0,38 %/etmal, respectively.Keywords: flowering, pruatjan, seed quality, morphology
