Penelitian ini bertujuan untuk mengetahui adaptasi tanaman ubijalar (Ipomoea batatas L.) dataran tinggi pada dataran rendah. Penelitian dilaksanakan di Tanjung Selamat Kabupaten Deli Serdang mulai bulan Mei sampai dengan Oktober 2017. Rancangan yang digunakan pada penelitian ini adalah rancangan acak kelompok. Hasil penelitian ini menunjukkan ubijalar G4 memiliki bobot umbi paling berat jika dibandingkan dengan genotip lainnya (466,67 g). G3 memiliki jumlah umbi paling banyak jika dibandingkan dengan genotip lainnya (4,67). G1 memiliki rataan bobot umbi paling berat jika dibandingkan dengan genotip lainnya (197,81 g). G1 dan G2 memiliki ketebalan korteks paling tebal jika dibandingkan dengan genotip lainnya (9 atau sangat tebal). Ubijalar dataran tinggi yang ditanam pada dataran tinggi lebih mudah beradaptasi dibandingkan yang ditanam pada dataran rendah. Dapat dilihat dari semua parameter produksi yang diamati.Kata kunci : adaptasi, genotip, karakter morfologis, ubijalar

TPD was a physiological caused by overstimulation ethylene an overproduction of reactive oxygen species (ROS). As an adaptive response, plant produce antioxidant such as secondary metabolites one of them was ascorbic acid (AsA). Exogenous application of AsA has been very effective in improving plant growth and development by altering oxidative defense system and induction of tannin synthesis in response to environmental stresses may also indicate potential functions. These Research aimed to provided activity of ascorbic peroxidase, tannin and production in Hevea brasiliensis Clones PB 260 affected Tapping Panel Dryness and to find the effect of ascorbic acid on production latex in in Hevea brasiliensis Clones PB. The research was conducted in rubber plantation of Sungei Putih Research Institute, Deli Serdang Regency North Sumatra with PB 260 as clone were planted in 2006 to 2007 at ± 54 m above sea level. The interval for treatment was once a week for 4 months. The observation was made 4th months after first application. The parameters observed were production, the activity of Askorbic peroxidase and tanin. The result showed Applicated ascorbic acid 150 ppm can increased the production of latex and tannins in rubber plants that are exposed to tapping panel dryness (TPD) but reduced the activity of the ascorbate peroxidase (Apx).

PENDUGAAN PEWARISAN GENETIK KARAKTER MORFOLOGI HASIL PERSILANGAN F2 TANAMAN KEDELAI (Glycine max (L.) Merr. PADA CEKAMAN SALINITAS Fachrina Wibowo; Rosmayati; Revandy I. M. Damanik

Salinitas menjadi salah satu ancaman bagi sistem produksi bahan pangan, termasuk kedelai. Salah satu strategi untuk mengatasi dan mengeliminasi penurunan produksi kedelai akibat meluasnya salinitas adalah merakit varietas toleran salinitas melalui persilangan. Seleksi merupakan tahap yang sangat menentukan keberhasilan tujuan pemulia dalam perakitan varietas unggul, dimana progeni yang terpilih berdasarkan mekanisme toleransi selanjutnya akan digunakan dalam perakitan varietas kedelai tahan salinitas dan berdaya hasil tinggi.Tujuan dari penelitian ini untuk menduga pewarisan genetik karakter morfologi hasil persilangan F2 tanaman kedelai pada cekaman salinitas. Penelitian dilaksanakan di Rumah kasa kebun percobaan Fakultas Pertanian Universitas Sumatera Utara, pada bulan Februari 2015 sampai dengan November 2015. Benih yang digunakan pada penelitian ini adalah seluruh benih F2 kedelai dari dua hasil persilangan, Varietas Anjasmoro (A) dan Grobogan (G) sebagai tetua betina dan varietas Grobogan yang telah mengalami beberapa tahap seleksi teruji tahan salin sebagai tetua jantan (N1, N2, N3, N4, N5) sehingga didapatkan 9 kombinasi genotipe hasil persilangan yaitu: AxN1, AxN3, AxN4, AxN5, GxN1, GxN2, GxN3, GxN4, GxN5 selanjutnya benih F2 tetua Anjasmoro, Grobogan, dan tetua N. Adapun metode penelitian yang digunakan adalah analisa Statistik Deskriptif, diman uji kenormalan sebaran data dan frekuensi genotipe generasi F2 dilakukan untuk masing-masing karakter dilanjutkan dengan uji heritabilitas. Hasil penelitian didapat pada hasil persilangan dari keempat karakter yang kemungkinan besar dapat terwariskan adalah karakter jumlah daun dan bobot biji per tanaman pada persilangan GxN.

Fast and applicable seed quality testing methods are needed to support the availability of quality seeds that can be distributed. The Tetrazolium Rapid Test Method is a rapid test method that is currently being implemented in Seed Quality Testing Laboratories. Meanwhile, the Radicle Emergence/RE Rapid Test method is currently being developed to accelerate the supply of quality seeds. This research aims to determine a more precise, efficient, and efficient method. Accurate in predicting corn seed germination in the laboratory and field. This research was carried out in the laboratory using a completely randomized design and in the field using a one-factor randomized block design, namely varieties in the form of ten varieties of corn (Sukmaraga, Srikandi Ungu, Srikandi Kuning, Pulut Uri, Lamuru, Bisi 18, Bisi 2, P32, P35, and Betras 1). The results showed that the Tetrazolium Rapid Test and the RE Rapid Test had a very close correlation in estimating the value of Seed Germination in the Laboratory and the Field. Both methods can be used as Rapid Test methods in Seed Quality Testing laboratories. However, the RE Rapid Test is more economical and practical.
