Abstract

The following observations on the seemingly prevalent occurrence of peanut (Arachis hypogaea) seed contaminations by PtMtV virus in the surrounding area of Palu, Central Sulawesi were conducted to determine the level of seed contamination and whether hot water treatment can be used to eliminate PtMtV virus from the seeds. Peanut seeds were collected from a number of locations and after soaking them in unheated water (29C) and heated water (55, 60 and 65C) for 10 minutes they were allowed to germinate, then transplanted and grown in pots in screen house. The effects of hot treatments on seed germinability, leaf formation, frequency of infection on surviving plants, and plant biomass production were determined. Seeds soaked in heated water showed different germinability, grew to become plants with different leaf formation and plant biomass production. Heat treatments gave different frequencies of infection on the plants. However, not a single heat treatment gave satisfactorily results in terms of giving zero or low infection and at the same time giving desirable seed germinability, leaf number, and plant biomass. The prospect of using hot water treatment at 55C or lower with longer soaking duration as a method for PtMtV virus elimination from peanut seeds is discussed.

Abstract

Bee keeping of local bee (Apis cerana Fab.) in Purbalingga Regency is spread widely from  25 m to 350 m asl, eventhough quatatively the production is still low. It is caused by parasitic mite attack,  Varroa jacobsoni. This mite attack then suck haemolymph of the pupae,  meanwhile if the bee comb cell  consist of more than one mites, the pupae will die, consequently the honey production will decrease. The aims of the research are: 1) to know a mount of individual mite living and caused the death of one bee pupae, .2) to define the correlationship between density of parasitic mite and honey production, 3). To differ parasite mite V. jacobsoni  density in longitudinal and cross posision of combs.  Method used was survey with purposive random sampling tehnique on two posision of bee comb, 15 samples were taken in each posision.  The data were analyzed  by counting the amount of mite living on every dead pupae and the correlation was analyzed for the relationship between relative density of parasite mite and  honey production. The result shows that correlation between relative density of parasitic mite and honey production is unsignificant. Conclusion of the research are: 1) amount of  parasitic mite living on bee pupae and causing death is 5,80 individual on cross posisition comb and 4,71 individual on longitudinal posision comb. 2) correlation between relative density of parasitic mite and honey production is unsignificant. 3). The relative density of parasitic mite between two posisions of comb is unsignificant.

Abstract

Phalaenopsis amabilis (L.) Blume merupakan salah satu anggrek alam dengan nilai komersial yang tinggi. Keberadaannya di alam semakin sukar dijumpai akibat eksploitasi berlebihan dan kerusakan hutan. Selain itu budidaya anggrek ini cukup sulit dilakukan karena biji bersifat mikroskopis dan tidak memiliki endosperm, sehingga perlu dilakukan kultur  in vitro. Dalam budidaya secara in vitro diperlukan medium pendukung pertumbuhan anggrek secara optimal misalnya dengan penambahan Zat Pengatur Tumbuh (ZPT) dari golongan auksin dan sitokinin. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan ZPT tersebut terhadap perkembangan protokorm (pertumbuhan embrio anggrek) P. amabilis secara in vitro dari aspek morfologi dan anatomi. Penelitian dilakukan di Laboratorium Bioteknologi dan Laboratorium Struktur Perkembangan Tumbuhan. Digunakan protokorm anggrek P. amabilis berumur 2 bulan. Protokorm disubkultur pada medium NP dengan kombinasi ZPT NAA dan TDZ pada berbagai konsentrasi dan diinkubasi pada ruangan dengan kelembaban tinggi, suhu 250C.  Kemudian diamati protokorm anggrek selama 2 minggu yang mencakup persentase pertumbuhan, persentase protokorm yang membentuk tunas dan absorbing hair. Pembuatan preparat anatomi dilakukan dengan mengambil protokorm setiap minggunya, disimpan dalam larutan alkohol 70% dan dibuat preparat anatomi menggunakan metode Parafin dengan pewarnaan safranin. Hasil penelitian menunjukkan pada penambahan NAA dan TDZ pertumbuhan protokorm mencapai 100%. Persentase protokorm yang membentuk tunas berturut turut (0:0, 0.2:0, 0:0.5, 0.2:0.5, 0:1, dan 0.2:1) ppm adalah 24%, 22%, 32%, 40%, 40% dan 38% sedangkan untuk pengamatan protokorm yang membentuk absorbing hair sebesar 10%, 18%, 14%, 24%, 16%, dan 0%. Untuk diameter sel berukuran 39.2±0.47µm, 44.4±0.97µm, 39.08±0.5µm, 38.83±0.2µm,39.5±0.39µm dan 39.75±0.28µm. Sehingga dapat disimpulkan medium yang paling optimal dalam pertumbuhan anggrek P. amabilis secara in vitro adalah medium NP dengan kombinasi NAA dan TDZ (0.2 : 0.5) ppm.Kata kunci : Anatomi, Kultur In Vitro, Morfologi, Phalaenopsis amabilis
