Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh asal stek dan zat pengatur tumbuh Atonik terhadap pertumbuhan dan produksi dua varietas ubi jalar. Penelitian ini dilaksanakan di lahan masyarakat bajak V, kelurahan Harjosari II kecamatan Medan Amplas, Sumatera Utara, Medan, dengan ketinggian tempat +33 m dpl, dilaksanakan pada bulan September 2015 sampai Januari 2016 menggunakan Rancangan Acak Kelompok dengan tiga faktor perlakuan yaitu varietas (Antin-1 dan Kidal), bahan asal stek (stek pucuk dan stek pangkal) dan zat pengatur tumbuh Atonik (0,25 ml dan 0,50 ml). Peubah amatan yang diamati adalah pertambahan panjang tanaman, jumlah umbi per sampel, panjang umbi per sampel, diameter umbi per sampel, bobot umbi per sampel, bobot umbi per plot dan uji organoleptik. Hasil penelitian menunjukkan bahwa varietas berbeda nyata terhadap pertambahan panjang tanaman, jumlah umbi per sampel, panjang umbi per sampel, diameter umbi per sampel, bobot umbi per sampel, bobot umbi per plot. Stek berbeda nyata terhadap pertambahan panjang tanaman, Interaksi antara varietas, stek, dan Zat pengatur tumbuh Atonik tidak berpengaruh nyata.

Abstract

The aim of the research was to know the effect of the time of soaking and level concentration of colchicines on the morphological differences and the number of chromosomes of the Aglaonema plants. The research was conducted at the screenhouse and plant tissue culture laboratory of Faculty of Agriculture, University of Sumatera Utara, Medan, Indonesia from January 2017 to June 2017. The young Aglaonema plants were soaked in 2 ppm, 4 ppm, 6 ppm for 6 hours and 12 hours. The result showed that the time of soaking, concentrate of colchicines, and  interaction of both did not significantly affect the parameter of percentage of living plants, plant height increase, number of leaves, and  number of shoots. The Aglaonema plants treated with the level concentration of colchicine perfomed the differences in morfological character and the number of chromosomes than the control. The highest number of chromosomes found in the treatment 6 ppm colchicine  for 12 hours soaking (37 pairs). Keywords       : aglaonema, chromosomes,  colchicine,  morphological differences

Abstract

Penelitian ini bertujuan untuk mengidentifikasi fenotipe tanaman pisang barangan (Musa acuminata Linn.) yang ada di Kabupaten Deli Serdang Sumatera Utara. Penelitian ini dilaksanakan di Kecamatan Sinembah Tanjung Muda Hilir Kabupaten Deli Serdang mulai bulan Maret sampai dengan Agustus 2017 menggunakan metode survei deskriptif dengan panduan descriptors for banana (International Plant Genetic Resources Institute) dengan teknik pengambilan sampel secara purposive sampling. Hasil penelitian ini menunjukkan bahwa hubungan kekerabatan terdekat ada pada sampel D1P1S1 dan D1P1S3 dengan nilai jarak terdekat senilai 0,000 dan hubungan kekerabatan terjauh pada sampel D1P3S3 dan D3P3S2 dengan nilai jarak terjauh senilai 5,000.

Abstract

Maize is one of the staple food crops in Indonesian that must be developed its genetic diversity. The objective of this study was to obtain the appearance of vegetative and reproductive character of some F1 maize populations on peat soil stress with pH criteria of 5.9 and peat soil with sludge and ash of oil palm. The research was conducted at Setiabudi field, Tanjung Rejo sub-district, Medan city from April to August 2017. This research used Randomized Block Design (RAK) with 2 treatment factors. The first factor is the population consisting of 5 levels:A (NEI9008 x CLA46), B: (NEI9008 x CLA106), C: (CLA106 x NEI9008),D: (CLA16 x CLA84), E: (CLA84 x NEI9008) and the second factor is planting medium consisting of 3 levels is M1 (peat soil), M2 (peat soil + ash of oil palm), M3 (peat soil + sludge). The results showed that the interaction of planting media with F1 population of maize plant had significant effect on plant height character. The best media is found in M3 (peat soil + sludge).
