Abstract

This study examined osmotic adjustment (OA) expression and solutes accumulated in leaf segments of wheat cultivar Hartog (with high OA capacity) exposed to polyethylene glycol (PEG). Osmotic adjustment (OA) is one of the traits that contribute to plant tolerance of water deficits. The objectives were to evaluate OA expression as response to increasing PEG concentration and treatment periods, and to examine the concentrations of inorganic and organic solutes in the tissues, as related to OA development at different duration of PEG treatments. The experiment consisted of 4 PEG treatments (0, -0.5, -1.0 and -1.5 MPa), 5 sampling times (0, 12, 24, 48 and 72 h) and 3 replicates. PEG treatments were imposed as -0.5 MPa steps, every 12 h. The leaf segments were sampled for leaf water content, osmotic potential, OA, inorganic solutes (K+, Na+ and Cl-), and organic solutes (glycinebetaine, proline and total soluble sugars). OA was expressed in leaf segments exposed to water deficit under PEG -0.5 MPa, but not at -1.0 MPa or higher. The differences of measurements in PEG -0.5 MPa compared to PEG -1.0 and -1.5 MPa, were clearly observed at 48 h. Amongst the solutes, Na+ and proline contributed to leaf OA.

Abstract

Tanaman Sansevieria yang dikenal sebagai tanaman hias ini memiliki keindahan pada warna dan bentuk daun, tergantung varietasnya. Ciri khas tanaman ini daunnya yang menjulur panjang seperti lidah. Penelitian ini bertujuan untuk menginventarisasi jenis-jenis tanaman Sansevieria yang dibudidayakan di Desa Ongkaw, Kecamatan Sinonsayang, Kabupaten Minahasa Selatan. Pengambilan data dilakukan dengan metode penjelajahan secara langsung. Morfologi Sansevieria yang ditemukan difoto dan diamati. Hasil penelitian di Desa Ongkaw menunjukkan adanya 11 jenis tanaman Sansevieria yang terdapat di tiga titik lokasi penelitian, yaitu diantaranya Sansevieria trifasciata laurentii, Sansevieria trifasciata, Sansevieria cylindrica, Sansevieria hahnii, Sansevieria stuckyi, Sansevieria pinguicula, Sansevieria kirkii, Sansevieria ehrenbergii, Sansevieria dracaena trifasciata moonshine, Sansevieria golden flame, Sansevieria mansoniana. Sansevieria trifasciata laurentii paling banyak ditemukan dibandingkan dengan jenis Sanseviera lainnya. The color and shape of the leaves of the Sansevieria plant, which is known as an ornamental plant, vary depending on the variety. This plant is distinguished by the length of its leaves, which resemble a tongue. The purpose of this study was to identify the different types of Sansevieria plants that are grown in Ongkaw Village, Sinonsayang District, South Minahasa Regency. The direct exploration method was used to collect data. The morphology of the discovered Sansevieria was photographed and observed. The results of research in Ongkaw Village showed that there were 11 types of Sansevieria plants found at three research locations, namely Sansevieria trifasciata laurentii, Sansevieria trifasciata, Sansevieria cylindrica, Sansevieria hahnii, Sansevieria stuckyi, Sansevieria pinguicula, Sansevieria kirkii, Sansevieria ehrenbergii, Sansevieria dracaena trifasciata moonshine , Sansevieria golden flame, Sansevieria mansoniana. When compared to other types of Sansevieria, Sansevieria trifasciata laurentii was the most common
