Abstract

In vitro regeneration of buds and shoots via organogenesis in two genotypes of snake plants (Sansevieria trifasciata) were established. Leaf segments (1 × 1cm) of ‘Hahnii’ and’Lorentii’ were cultured on Murashige and Skoog (MS) basal medium containing 2,4- dichlorophenoxyacetic acid (2,4-D) for 1 week, transferred into MS medium without plant growth regulator (MS0) for 1 week, and then cultured on MS medium containing different concentrations of N6-benzyladenine (BA) at 0, 0.1, 0.25, 0.5, 1.0 and 2.0 mg/l in three times of serial passages with 4 week intervals. The results showed that regeneration of S. trifasciata was established via indirect organogenesis. ‘Lorentii’ was more responsive on shoot regeneration than ‘Hahni’. The most suitable BA concentration for shoot bud and shoot regeneration for both cultivars was 2 mg/l. Explants of ‘Lorentii’ cultured on MS medium containing 2.0 mg/l BA produced 8.6 shoot buds and 3.4 shoots per explant after 14 weeks. Shoots derived from both cultivars were successfully ex vitro rooted and acclimatized in the greenhouse with high survival rate, i.e., from 96 -100%.

Abstract

Attempts to identify somaclonal variants of peanut with resistance to Sclerotium stem rot disease due to infection of S. rolfsii were conducted. The objectives of this study were to develop in vitro selection method using culture filtrates of S. rolfsii, identify culture filtrate-insensitive somatic embryo (SE) of peanut after in vitro selection and regenerate peanut R0 lines originated from culture filtrate-insensitive SE. To achieve these objectives, peanut embryogenic tissues were cultured on selective medium containing various concentrations of S. rolfsii culture filtrates and sublethal concentration of the filtrates. Medium containing sublethal level of S. rolfsii culture filtrates was used to identify culture filtrate-insensitive SE of peanut. Subsequently, the selected SEs were germinated, plantlets were regenerated and preliminary tested against S. rolfsii. Results of the experiments showed that addition of S. rolfsii culture filtrates into medium for inducing peanut somatic embryos drastically reduced their growth and proliferation. S. rolfsii culture filtrates at 10% concentration has significantly reduced the number of proliferated SE per explant. However, sublethal level was achieved at 30% of culture filtrates concentration. Responses of five peanut cultivars against 30% of culture filtrates were similar, indicating they were similar in their susceptibility against S. rolfsii. A number of culture filtrate-insensitive SE were identified after culturing 1500 clumps of embryogenic tissue of peanut cv. Kelinci for three consecutive passages on medium containing 30% of culture filtrates. Germination of selected SE and regeneration of plantlet from culture filtrate-insensitive SE resulted in 50 peanut R0 lines. These lines have been grown in the plastic house and produced normal seeds for further evaluation. Results of S. rolfsii inoculation indicated the existence of chimera for insensitivity against S. rolfsii.

Abstract

Tingginya AKI tidak terlepas dari kejadian perdarahan, eklamsi dan infeksi. Disisi lain penyebabnya adalah masih banyak ditemukan masalah kehamilan yang tidak ideal (terlalu banyak anak, usia ibu terlalu muda, usia ibu terlalu tua, dan terlalu dekat jarak kehamilan) yang sangat membahayakan bagi keselamatan ibu yang lebih dikenal dengan 4T. Kehamilan yang berisiko tinggi mengundang masalah sampai keselamatan jiwa saat melahirkan. Penelitian ini dilakukan untuk melihat hubungan pengetahuan dan sikap ibu hamil dengan kehamilan risiko tinggi (4T) di BPM Desita, S.SiT Desa Pulo Ara Kecamatan Kota Juang Kabupaten Bireuen.Desain penelitian yang digunakan dalam penelitian ini yaitu analitik cross sectional. Populasi dalam penelitian ini adalah seluruh ibu hamil yang datang ke BPM Desita, S.SiT Desa Pulo Ara Kecamatan Kota Juang Kabupaten Bireuen. Teknik pengambilan sampel dalam penelitian ini yaitu dengan cara accidental sampling sebanyak 42 orang.Dari hasil penelitian yang dilakukan terhadap 42 responden yang dilakukan pada Februari 2021 menunjukkan bahwa ada hubungan antara pengetahuan dengan kehamilan risiko tinggi (4T) di BPM Desita, S.SiT Desa Pulo Ara Kecamatan Kabupaten Bireuen. Ada hubungan antara sikap dengan kehamilan risiko tinggi (4T) di BPM Desita, S.SiT Desa Pulo Ara Kecamatan Kabupaten Bireuen.         Diharapkan kepada responden untuk lebih maksimal lagimen dalam konsep tentang risiko tinggi 4T pada masa kehamilan, sehingga ibu tidak lagi merencanakan kehamilan jika berisiko terjadi masalah selama hamil ataupun efek pada persalinannantinya. Kata Kunci                  : Pengetahuan, Sikap, Risiko Tinggi 4T
