Abstract

This study was aimed at determining peanut varieties that are tolerant to drought stress and assessing the effectiveness of the use of PEG 4000 as a media simulation to drought stress.  Experiment was arranged in a Completely Randomized Design (CRD) factorial 4 x 4, repeated three times. First factor was variety, consisted of four levels, namely Tuban, Bima, Bison and Local Aceh. Second factor was PEG concentration, consisted of 4 levels, namely control, 3.5%, 11.6%, and 18.1%. Variables measured were maximum growth potential, germination rate, relative growth rate, vigor index, germination value, root length, hypocotyl length, and seedling dry weight.  The results showed that varieties exerted significant effects on maximum growth potential, germination rate, relative growth rate, root length, and hypocotyl length. PEG concentration exerted significant effects on maximum growth potential, germination rate, growth velocity, relative vigor index, germination value, root length, hypocotyl length, and seedling dry weight. There were interactions between varieties and PEG concentration on relative growth rate, root length, and hypocotyl length of groundnut seeds. Local variety of Aceh was recommended as a tolerant variety to drought stress.  Bison was not tolerant to drought stress. Bima was recommended as a moderate tolerant variety to drought, while Tuban was a tolerant variety to drought.

Abstract

The effect of antioxidants  as pre-storage treatment to expand the cotton seed storage period Halimursyadah1 dan Endang Murniati2 1Fakultas Pertanian Unsyiah, Nanggroe Aceh Darussalam2Fakultas Pertanian Institut Pertanian Bogor,Bogor ABSTRACTCotton (Gossypium hirsutum L.) seeds ‘Kanesia 8’ were treated with antioxidants to maintain viability and vigor during ageing.  Antioxidants which were used are α-tocopherol and extract of red fruit) dissolved in acetone, ascorbic acid dissolved in water also.   Seeds were stored at 70-80% relative humidity and 28-29ºC for 12 weeks.  Periodically, viability and vigor were determined.  Seed viability and vigor were estimated by percentage germination, speed of germination, T50, and Index of vigor.  Seeds treated with α-tocopherol 150 ppm showed the highest viability and vigor during the ageing period, while ascorbic acid 300 ppm also retarded the rate of ageing.  Treating seeds with red fruits showed the highest of T50.  The ability of α-tocopherol, ascorbic acid and red fruit to reduce viability and vigor loss of stored cotton seeds may be due to their ability to inhibit lipid peroxidation.

Abstract

ABSTRACT The objective of this study was to evaluate anatomical changes and oligosaccharide content of recalcitrant seed Avicennia marina at various drying rate i.e. fast, medium and slow drying.  Oligosaccharide content was determined, and anatomical embryonic axes was observed at various times during desiccation. The result showed that moisture content of  A. marina seed was 60.75-64.67% at shedding. The highest ratio of (raffinose + stachyose) / sucrose was 0.41, indicating that embryonic axes were more tolerant to desiccation than cotyledon.   Anatomical observation of embryonic axes showed that there was radicle damage due to  medium and slow drying treatment.

Abstract

Abstrak. Penelitian ini bertujuan untuk mengetahui pengaruh dosis jamur mikoriza arbuskula dan umur pindah tanam kecambah terhadap pertumbuhan bibit pala (Myristica fragrans). Penelitian ini dilaksanakan di Kebun Percobaan dan Laboratorium Ilmu dan Teknologi Benih Jurusan Agroteknologi, Fakultas Pertanian, Universitas Syiah Kuala pada bulan April sampai Juli 2020. Rancangan yang digunakan merupakan Rancangan Acak Kelompok (RAK) pola faktorial 4x3 dan diulang sebanyak 3 kali sehingga terdapat 12 kombinasi perlakuan atau 36 satuan percobaan. Satuan percobaan yang diuji menggunakan 5 tanaman dengan jumlah sampel sebanyak 3 tanaman. Faktor yang diamati yaitu dosis mikoriza arbuskula (M) yang terdiri dari 4 taraf (0, 10, 20 dan 30 g/ tanaman) dan umur pindah tanam kecambah dengan 3 taraf (30, 45 dan 60 HSS). Hasil dari penelitian menunjukkan bahwa perlakuan dosis mikoriza arbuskula 10 g/tanaman menghasilkan pertumbuhan bibit pala yang cenderung lebih baik pada semua parameter yang diamati. Sedangkan pada perlakuan umur pindah tanam kecambah, pertumbuhan bibit pala terbaik dijumpai pada perlakuan 60 hari setelah semai yang dapat dilihat dari hasil tinggi tanaman, diameter batang, jumlah daun, berat berangkasan basah, berat berangkasan kering dan berat kering akar.The Effect Mycorrhizae Dosages and Transplanting Age of   Sprouts Growth of Nutmeg Seeds (Myristica fragrans)Abstract. This research aims to get information the effect mycorrhizae dosages and transplanting age of sprouts on growth of nutmeg seeds (Myristica fragrans). This research was conducted in the experimental garden and the Seed Science and Technology Laboratory of the Faculty of Agriculture, Syiah Kuala University from April to July 2020. The research used a block random design 4x3 factorial pattern  with 3 replications. Factors studied were mycorrhizae dosages consisting of 4 levels (control, 10, 20, and 30 g/plant) and transplanting age of sprouts consisting of 3 levels (30, 45, and 60 DAP). The results of the study showed that the dose of arbuscular mycorrhizal treatment of 10 g/plant resulted in the growth of nutmeg seedlings which tended to be better on all parameters observed. While in the treatment of transplanting age, the best growth of nutmeg seedlings was found in the treatment 60 days after sowing which could be seen from the yield of plant height, stem diameter, number of leaves, wet root weight, dry root weight and root dry weight.
