Nepenthes, also known as pitcher plant, are unique and interesting flora developed as ornamental plants. This species has an attraction not only on the flowers but also on the diverse shapes and colors of the pitchers. Each Nepenthes species and hybrid has a variety of characters. The genetic relationship and diversity in Nepenthes species and hybrids can be determined based on the morphological characterization. The purpose of this study was to determine the similarity level among the Nepenthes accessions based on 31 qualitative characters. In this study, 30 Nepenthes species and 11 hybrids were used. The range of the similarity coefficient of Nepenthes species was 0.28-0.65, and divided into two major groups namely group A and B. Group A was the Nepenthes population which had petioles consisted of 17 accessions, while group B had folius consisting of 24 accessions. It indicated that when the similarity value is higher, the similarity level between each plant becomes higher. Principle Coordinates Analysis (PCoA) provided an overview of the relationship among the genotypes in coordinates. Species with a high similarity coefficient were in a close position, whereas species with a low similarity coefficient were in a remote position. Based on the PCoA, the species were grouped based on the similar characters, which was supported by the dendrograms.
The study aimed to determine the response of Pakcoy (Brassica rapa L.) to the Application of Coconut Dregs Compost and Pearl NPK (16:16:16). This study used a factorial completely randomized design consisting of two factors. The first factor is the provision of coconut dregs compost consisting of four levels, namely 0 g/plant, 150 g/plant, 300 g/plant, and 450 g/plant.The second factor is the provision of NPK Mutiara fertilizer (16:16:16) which consists of four levels, namely 0 g/plant, 4 g/plant, 8 g/plant, and 12 g/plant. The parameter observed was the Number of Leaves, Economical Wet Weight, Weight Dry, and Root Volume. The data were statistically analyzed and continued with the Difference Test Real Honest (BNJ) at the 5% level. The results showed that the interaction of coconut dregs compost and pearl NPK 16:16:16 have a significant effect on parameters Number of Leaves, Dry Weight, and Root Volume. Compost best treatment coconut dregs 450 g/plant and NPK pearl 16:16:16 12 g/plant. The main influence effect of coconut pulp compost was significantly on all parameters. The best treatment dose of coconut pulp compost is 450 g/plant. The main influence pearl NPK fertilizer 16:16:16 had a significant effect on all parameters. The best treatment of pearl NPK fertilizer 16:16:16 12 g/plant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
