Abstract. Shintiavira H, Sulistyaningsih E, Purwantoro A, Wulandari RA. 2020. The effects of gibberellic acid (GA3) on the harvesting time of spray type Chrysanthemum cut flowers in medium land. Biodiversitas 21: 1723-1729. The high temperature of the medium land causes a delay in harvesting time and also decreases the diameter of Chrysanthemum cut flowers (Chrysanthemum morifolium R.). It is, however, possible to accelerate and increase the flower diameter through the use of the Gibberellic acid (GA3). This research, therefore, aimed to obtain the best GA3 concentration to accelerate harvesting time using three varieties of spray type Chrysanthemum cultivated on a medium land. The experimental design involved the use of a split-plot with three replications. The main plot varied the GA3 concentration between 0, 200, 400, and 600 mgL-1 while the subplot used the spray type Chrysanthemum varieties such us ‘Yastayuki’, ‘Arosuka Pelangi’, and ‘Socakawani’. It was applied on the 56, 63, and 70 days after planting (DAP). The data were analyzed using Analysis of Variance (ANOVA) and a further test was conducted using Duncan Multiple Range Test (DMRT) at ?=0.05. The results showed GA3 at 400 mgL-1 was the best concentration to increase the harvesting time in all varieties. However, the harvesting time of spray type without secondary branching (‘Arosuka Pelangi’) was faster than spray type with secondary branching (‘Yastayuki’ and ‘Socakawani’). The harvesting time was earlier 13, 9, and 7 days for ‘Arosuka Pelangi’,’Yastayuki’ and ‘Socakawani’ compare with control, respectively. The average diameter of the blooming flowers was also wider with 54.9 mm compared to the control treatment which was 38.7 mm.

Abstract. Jalil M, Purwantoro A, Daryono BS, Purnomo. 2020. Distribution, variation, and relationship of Curcuma soloensis Valeton in Java, Indonesia based on morphological characters. Biodiversitas 21: 3867-3877. Curcuma soloensis Valeton (locally called temu genyeh) was a plant originating from Solomon Islands and was synonymous with Curcuma longa L. This plant was often considered to be turmeric (Curcuma longa Linn.) or temulawak (Curcuma zanthorrhiza Roxb.), because the rhizome is almost the same color. The purpose of this study was to determine the distribution, variation, and relationship of C. soloensis in Java, Indonesia. Retrieval of data with exploratory roaming methods in 12 districts/cities in Java Island as a center for planting medicinal plants. Morphological character observations were made on habit, rhizome, roots, tubers, leaves, pseudo-stems, and flowers. Morphological data were analyzed by descriptive and numerical methods. Analysis of grouping with Gower Coefficients because it uses 45 binary and multistate data. Principal Component Analysis (PCA) was performed to determine the role of each character in the grouping. Cluster analysis and PCA graphics were assisted with MVSP 3.1 software. The results of the study were obtained from 25 accessions of C. soloensis in East Java (Trenggalek, Pacitan, Ponorogo), Central Java (Wonogiri, Karanganyar, Magelang, Semarang), Yogyakarta (Yogyakarta City, Bantul, Gunungkidul), and West Java (Ciamis and Tasikmalaya). The variation of C. soloensis lies in habit, stem color, leaf shape, rhizome shape, rhizome flesh color, and tuber shape. The highest abundance percentage is in Pajangan, Tirtomoyo, and Tawangmangu. The dendrogram divides 32 OTUs into two clusters on the phenon line 0.617, namely cluster A (C. zanthorrhiza) and cluster B (C. soloensis and C. longa). PCA results showed that the characters that had the most role in grouping were leaf blade color, leaf blade length, rhizome shape, root color, rhizome taste, outer and inner rhizome flesh color.
