Abstract

Porang (Amorphophallus muelleri Blume) merupakan salah satu tanaman bergizi yang memiliki asam oksalat yang berdampak negatif bagi kesehatan manusia. Pupuk P dan K diduga dapat digunakan untuk mereduksi kandungan oksalat pada porang. Tujuan penelitian ini adalah untuk mengetahui  pengaruh pemberian pupuk P dan K secara tunggal maupun kombinasi pada kandungan oksalat umbi porang dan mengetahui jenis dan dosis pupuk yang dapat mereduksi kandungan oksalat. Perlakuan terdiri dari kombinasi empat dosis pupuk K dan empat dosis pupuk P dengan dosis yang sama yaitu 0;2,16;4,32;dan 6,36 g/12 kg tanah yang diaplikasikan ke tanaman porang yang ditumbuhkan hingga empat bulan. Oksalat terlarut dianalisis dengan volumetri dan oksalat tidak terlarut dianalisis dengan spektrofotometri (AAS). Analisis statistik menggunakan ANOVA dilanjutkan uji Tukey α = 5%. Kombinasi pupuk P dan K serta pupuk P tunggal tidak mempengaruhi kandungan oksalat terlarut, tidak terlarut, dan total pada umbi porang. Pemberian pupuk K tunggal pada dosis 2,16 g/12 kg tanah mampu menurunkan kandungan oksalat total sebanyak 34,3 %. Dengan demikian dosis Pupuk K ini berpotensi untuk menurunkan kandungan oksalat total umbi porang.   Kata kunci : oksalat, pupuk K, pupuk P, spektrofotometri, volumetri

Abstract

When obtaining plantlets, embryo maturation and simultaneous germination are important steps in plant micropropagation via somatic embryogenesis. Several studies have shown that the use of carbohydrates as a carbon source plays a significant role in inducing somatic embryo development in certain plant species. This study aimed to establish a somatic embryo maturation protocol for Batu 55 Mandarin (C. reticulata Blanco.) by examining the effect of various types of sugar and concentrations. The results showed that the type and concentration of sugar added to the medium affect the somatic embryo maturation of Batu 55 Mandarin. Galactose and maltose enhance somatic embryo maturation more effectively than does sorbitol. The combination of galactose or maltose with sorbitol was able to improve somatic embryo maturation more effectively than galactose or maltose alone. The combination of galactose and sorbitol enhanced the maturation of somatic embryos more effectively than did change the concentrations of maltose or sorbitol. It can be concluded that sugar type and concentration had effects on citrus somatic embryo development. The combination of sorbitol (36.5 mM) with galactose 73 mM was able to augment citrus somatic embryo maturation more effectively than the other concentrations applied.

Abstract

Background: The relationship of plant kinship can be done through the identification of the phenotype character that is the character that appears on the individual or plant organism that can be both quantitative and qualitative. The purpose of this research is to know the diversity and kinship of corn cultivar from Kisar Island Regency of Maluku Southwest of Maluku Province based on phenotype character. Methods: The genetic material used was six local corn cultivars and one comparative variety. The six local corn cultivars are Red ruby with a brown cob, Blood red corn, Sticky, Ripe yellow, Deep yellow, and White, while the varieties are Srikandi varieties. To know the effect of cultivars and corn varieties on phenotypic diversity, variant analysis with Statistica Analytical System (SAS version 9.0) was used. To know the character that gives the greatest contribution to the diversity of cultivar phenotype and corn varieties, the main component analysis is done. To know the kinship among corn cultivars based on phenotypic character, gross analysis (cluster analysis) with hierarchy method is performed. The main component analysis and gameplay analysis was performed using SPSS version 18.0 computer program. Results: The results of variance analysis showed a significant effect of maize cultivar on phenotypic diversity. Characters that contribute to the diversity of the corn cultivar phenotype are the proline level, the weight of cobs without harvesting at harvest, the weight of cobs without dryness of the oven, the weight of the cobs at 12% moisture content, the unleaded cobs at 12%, the diameter of the ear, the number of seeds per ear, the number of rows of beans per ear, the number of leaves, and the length of the leaf. The results of Euclidean and Euclidean girder analysis show that the local yellow cultivars are in one group alone and have a low similarity with other local corn cultivars as well as the Srikandi-based varieties based on their phenotypic characters. Conclusion: There is a variety of phenotypes of local corn cultivars and varieties of Srikandi compounds grown on Kisar Island of Southwest Maluku Maluku Province.

Abstract

Indonesia is the third richest country for pigmented rice source. Morphological character of pigmented rice in Indonesia is less reported since recent publications and descriptions of pigmented rice are only limited to black rice of Cempo Ireng variety and red rice of Aek Sibundong variety. Pigmented rice varieties in Indonesia are cultivated in an organic way. These varieties are Wojalaka black rice of East Nusa Tenggara (NTT), Manggarai of NTT, Toraja of South Sulawesi, Cempo Ireng of Central Java and red rice of Aek Sibundong (leading variety) and Baubau of Southeast Sulawesi. The objective of research was to compare the morphological variation of root, stem, leaf, panicle, floret and the colour of milk mature grain and mature grain by observing the vegetative and generative parts of six local rice varieties. Research had been conducted from February 2012 to February 2014 in Sengguruh Village, Kepanjen District, Malang Regency. This study type was quasi-experiment with eleven replications. Group Random Design was used. The observation was given upon vegetative, reproductive and maturity phases as groups. Independent variables in this research were six rice varieties, while the dependent variable was morphological variation (root, stem, leaf, panicle, floret, milk mature grain and mature grain). The data of morphological variation were tabulated through MS Excel 2007 for windows. Descriptive data analysis was used to determine the average rate and the deviation standard of each variable. Data were analyzed by ANOVA at a cut off value of α of 0.05. It was followed by HSD Tukey Test facilitated by SPSS 16.0. The analysis of multivariate data in cluster and biplot was carried out with PAST. The result of the study indicated that there was morphological difference on stem, leaf, panicle, floret, milk mature grain and mature grain. The colour of the stem in Aek Sibundong variety was purple, while that of other varieties was green. Toraja and Manggarai varieties had the highest height with 163-168 cm, followed by Cempo Ireng with 139 cm, Wojalaka and Baubau with 110-112 cm. Aek Sibundong Variety had the lowest height with 99 cm. Aek Sibundong and Wojalaka varieties had 6-7 internodes which were the greatest number of internode, while other varieties only had 4-5 internodes. Some varieties, such as Aek Sibundong, Wojalaka and Baubau had short and small leaf. The leaflet angle of Aek Sibundong and Baubau were 140 and it might be said as upright, while that of Wojalaka was 430 or moderate. Cempo Ireng, Manggarai and Toraja had its 63-880 of the leaflet angle or it was said as flat. Cempo Ireng and Wojalaka were included into Rice Indica Group while Toraja, Manggarai, Cempo Ireng and Baubau belonged to Rice Javanica Group. There were two morphological groups. Group 1 included Toraja, Manggarai and Cempo Ireng, while Group 2 consisted of Aek Sibundong, Baubau and Wojalaka.
