ANATOMICAL CHARACTERIZATION OF SELECTED PLANLET Vanilla planifolia Andrews. ON FUSARIC ACID, RESISTANT TO Fusarium oxysporum f. sp. vanillae

Vanilla is one of the important agricultural export commodity of Indonesia. The vanilla from Indonesia is well known for it high levels of vanillin content,which is about 2,75%. Until recently, the most hazardous disease of vanilla is foot rot infection caused by Fusarium oxysporum f. sp.vanillae (Fov). One alternative way to control the foot rot disease is by using cultivars which resistant to its pathogen. Selected plantlets have been induced by using fusaric acid on the in vitro medium. The goal of this research is to characterize the anatomical point of few especially on leaves, pseudo bulb and root with respect of resistant to Fov. Moreover, it is also addressed to determine the different characters of the phenotype vanilla plantlet whichare total of phenol, peroxydases enzyme activity, the thickness of lignin, and the chlorophyll content. The data on this research were recorded, compiled and categorized as descriptive qualitative and quantitative information. Theresult showed significant increase in chlorophyll a, chlorophyll b, and also the total of chlorophyll. The overall in line correlated with the increasing FA concentration. The total chlorophyll at 90 ppm FA could increased about 1,2 times, while at 100 ppm and 110 ppm FA could enhanced about 1,4 to 1,5 times compared to control. Anatomical characters between vanilla control, infected fov, and resistant to fov, were showed clearly at the stele part especially at xylem as the main function for transporting water from root to the leaf, which formed thyllose. Phenol total at about 4,39 % in control, increased to 5,34% in 90 ppm, and followed by 5,52 % in 100 ppm and 5,87 % at 110 ppm. Peroxidases enzyme activity at FA 90 ppm produced about 0,25 U/mg/min, and at 100 ppm FA on 0,34 U/mg/min, while at FA 110 ppm generated 0.36 U/mg/min compared to control, at 0,12 U/mg/min. The thickness of lignin tracheid in the treatment of 90 ppm was at about 14,59 ìm; 100 ppm 18,16 ìm; and 110 ppm 19,39 ìm compared to controls 10,28 ìm. In conclusion over all showed that FA induced plantlet vanilla inin vitro medium resulted in change of phenotype compare to control, which also affect its anatomy structure, especially on lignification and thyllose formation at surrounding tracheids, which could be use as marker for defend mechanism of plant to Fov.Keywords: Fusarium oxysporum f. sp.Vanillae, peroxydases enzyme, anatomical characters

IN VITRO SELECTION ON FUSARIC ACID OF Vanilla planifolia PLANTLETS FOR OBTAINING A CULTIVAR, WHICH RESISTANT TO Fusarium oxysporum f. sp. vanillae

The most production constrain on Vanilla planifolia Andrews plantation recently has been caused by foot rot disease that later influence in decreasing the yield product. This disease is caused by Fusarium oxysporum f. sp. vanillae (Fov). So far, the disease has not been successfully prohibited although some experiments had been conducted. The use of foot rot resistant cultivar has been introduced, which expected has high yield as one alternative method for controlling this disease. A resistant vanilla plantlet to Fov has been initiated by in vitro selection on MS medium containing fusaric acid (FA) on selective concentration. The purpose of research were to study and determine: 1) The proper combination of 2,4-D and NAA for callus initiation and shoot development from shoot tip explants, along with proper concentration of BAP for shoots initiation from nodal explants; 2) The FA concentration of plantlet selection tolerant to steady growth; 3) The proper concentration of FA for in vitro selection for suppressing the Fov. Results showed that: 1) the proper concentration of both combination between 2,4-D and NAA is about 2,0 mg/L and 10 mg/L respectively for callus initiation and shoot development from shoot tip explants; also the BA concentration is 1,0 mg/L for shoot initiation from a nodal explants; 2) the FA tolerant concentration for plantlet selection with vanilla steady growth is between 90 ppm-110 ppm; 3) the 110 ppm of FA was effective for suppressing the Fov compared to 90 ppm and 100 ppm respectively.Keywords: Vanilla planifolia Andrews, the vanilla foot rot disease, Fusarium oxysporum f.sp. vanillae, in vitro, fusaric aci

Analisis Profil Protein Pada Tahap Perkembangan Buah Kacang Tanah (Arachis Hypogaea (L.)

Perkembangan buah kacang tanah hanya terjadi di dalam tanah. Organ yang membawa buah masuk ke dalam tanah adalah ginofor yang terbentuk setelah fertilisasi terjadi. Apabila buah tidak masuk ke dalam tanah maka, embrio, biji dan buah kacang tanah tidak dapat berkembang. Setiap tahap dari perkembangan tumbuhan dipengaruhi oleh protein spesifik. Penelitian ini bertujuan untuk mengetahui profil protein pada setiap tahap perkembangan buah kacang tanah. Analisis profil protein dilakukan pada beberapa tahap perkembangan buah yaitu pada umur 0, 4, 6, 15, 18 dan 23 hari setelah anthesis (hsa), baik pada buah yang berkembang (masuk ke dalam tanah) maupun tidak berkembang (tidak masuk ke dalam tanah), serta akar, batang dan daun menggunakan metode SDS-PAGE (sodium dodecyl sulphate-polyacrylamide gel electrophoresis). Profil protein pada buah berbeda dengan profil protein pada akar, batang dan daun. Protein dengan berat molekul 124 kDa kemungkinan berperan dalam mengontrol perkembangan buah kacang tanah
