Kebutuhan kentang yang semakin tinggi menyebabkan permintaan semakin meningkat. Rendahnya produksi kentang mengakibatkan berbagai upaya untuk peningkatan produksi terus dilakukan. Penggunaan metode kultur jaringan yaitu metode untuk mengisolasi bagian tanaman seperti protoplasma, sel, sekelompok sel, jaringan dan organ dalam kondisi aseptik, sehingga dapat diperbanyak dan beregenerasi menjadi tanaman utuh dapat dijadikan alternatif pemenuhan kebutuhan. Penelitian ini bertujuan untuk mengetahui kecepatan pembentukan umbi mikro kentang (Solanum Tuberosum L.) varietas granola kembang secarain vitro dengan menggunakan dua faktor dan 3 kali ulangan. Faktor pertama yaitu aspirin dengan tiga taraf (5,10,15) ppm. Faktor kedua yaitu kinetin dalam tiga taraf (8,10,12) ppm. Penelitian menggunakan seluruh propagul kentang yang berumur 30 hari setelah subkultur dan data yang didapat dianalisis menggunakan ANOVA. Hasil penelitian menunjukan bahwa interaksi aspirin dan kinetin tidak berpengaruh terhadap jumlah akar, kedinian umbi, dan bobot umbi. Interaksi perlakuan terbaik bagi pembentukan tunas yaitu A2K1 aspirin 10 ppm dan kinetin 8 ppm sedangkan Interaksi perlakuan terbaik pada parameter jumlah umbi yaituA3K2 aspirin 15 ppm dan kinetin 10.

Tujuan penelitian ini adalah mengidentifikasi toksisitas beberapa fungisida nabati dalam mengendalikan penyakit Layu Fusarium (F. oxysporum) pada tanaman kentang (Solanum tuberosum L.) secara In Vitro. Metode Penelitian yang digunakan yaitu metode umpan beracun. Data dianalisis dengan Rancangan Acak Lengkap (RAL) dengan Analisis Varian (ANAVA) yang dilanjutkan dengan menggunakan metode BNT (Beda Nyata Terkecil). Hasil Penelitian, diperoleh nilai toksisitas fungisida nabati tertinggi yaitu pada ekstrak daun sirsak dengan nilai HR (69,44%), kategori berpengaruh, ditandai dengan diameter koloni 2,75 cm (100ppm) dan yang terendah toksisitasnya yaitu pada ekstrak daun jeruk purut dengan nilai HR (49,81%), kategori cukup berpengaruh ditandai dengan diameter koloni 3,75 cm (25ppm).

The purpose of this study was to determine the toxicity of several biofungicides in controlling Fusarium wilt (F. oxysporum) in potato plants (Solanum tuberosum L.) in Vitro. The research method used was the In Vitro method with the poison bait method. Data were analyzed by Completely Randomized Design with Variant Analysis (ANAVA), followed by the BNT method. The results showed that the highest biofungicide toxicity value was soursop leaf extract with HR values (69.44%), influential categories, characterized by colony diameter 2.75 cm (100ppm) and the lowest toxicity, namely in kaffir lime leaf extract with a value of HR (49.81%), quite influential category was characterized by colony diameter of 3.75 cm (25ppm). The higher the concentration tested, the higher the toxicity of the biofungicide given.Keywords: biofungicides, Fusarium oxysporum, Potato Plants, In Vitro.

Одним из этапов технологического процесса производства оригинального семенного картофеля является выращивание оздоровленных пробирочных микрорастений в весенне-летней теплице для получения мини-клубней. Исследования проводили в Приморском крае на оздоровленных безвирусных пробирочных растениях картофеля (Solanum tuberosum L.) сорта Метеор, размноженных методом микрочеренкования в культуре in vitro. Данный сорт был выбран вследствие его скороспелости. В ходе эксперимента при выращивании микрорастений изучено влияние сочетания факторов — объем пробирок, состав почвенного грунта и площадь питания растения на производство мини-клубней картофеля в условиях искусственного освещения. Дана оценка продуктивности пробирочных растений и определена роль основного фактора, влияющего на выход мини-клубней картофеля сорта Метеор, в лабораторных условиях. Установлено, что основное влияние на производство стандартных мини-клубней картофеля оказал состав почвенного грунта. Максимальное количество стандартных мини-клубней картофеля сорта Метеор (209,3 и 156,1 шт./м2) получено в вариантах опыта при использовании грунта с содержанием элементов питания: фосфора — 1380 мг/кг, калия — 1425 мг/кг, азота — 1394 мг/кг, органического вещества — 66,7 %.

Abstract This study was performed to reveal the changes in cell division, as a result of the prolonged period of subculture on micropropagation medium, of five local varieties of Solanum tuberosum L. maintained on in vitro collection at Suceava Genebank, Romania. For this purpose it was used the Murashige-Skoog medium (MS- 1962) with addition of 40 g/l sucrose, and 6 mg/l daminozide. The effect of prolonged period of subculture up to two and 12 months was expressed as mitotic index and frequency of cells with abnormal division. Mitotic index ranged from 20.1 to 22.1% after 12 days, between 15.5 - 17.7% after two months and between 17.7 - 19.2% after 12 months of subculture. The results obtained showed that the frequency of aberrant cells increased with the preservation time on the in vitro cultures and their accumulation rate depended on the genotype. Were identified interphases with micronuclei, metaphases with retarded chromosomes, ana-telophases with chromosomal bridges, retarded chromosomes and chromosomal fragments, but their percentage was low in all the genotypes.

Role Of Light

The aim of this study is to determine the effects of different concentrations and combinations of the phytohormones, 1-naphthaleneacetic acid (NAA), and 6-benzylaminopurine (BAP): M1 (0.5 mg / l +1 mg / l), M2 (1 mg / l + 0.5 mg / l) , M3 (2 mg / l +2 mg / l), M4 (0.5 mg / l + l mg / l, NAA), M5 (1.0 mg / l + l mg / l , NAA), and M6 (2.0 mg / l + l mg / l, NAA). This study was carried out in dark condition on callus induction of potato plants (Solanum tuberosum L.) cultivars from potato tuber bud so as to demonstrate the role of light. The callus initiation begins after 7 days of incubation for all studied media. After two months of incubation, the better development of callus was noted in Spunta variety by using medium M1, M2, M3, and M6. The calluses took a compact structure of brown-white color for both varieties with a callus induction rate of 20- 40%. This was collected with kondor variety for M2 and (M3, M4, M5) media respectively and 10-30% for M4 (M1, M2, M3) for Spunta variety also. The highest fresh weight was recorded on M2 medium with 0.26g for Kondor variety and 0.93g for Spunta variety.
