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.

Four Levels

In supporting the replacement of potato varieties with the varieties that are adaptive to drought, effective and fast methods are needed. One of which is through in vitro screening of drought-tolerant genotypes. The aims of this research were to determine the appropriate concentration of sorbitol as a critical limit in the in vitro screening process of drought-tolerant genotypes, as well as to determine vegetative characteristics that could be used as indicators of in vitro selection and also to obtain in vitro drought-tolerant genotypes. To achieve these objectives, we used single-nodal explants of seven genotypes cultured for six weeks on MS media added with four levels of sorbitol concentration. Of the four treatments, sorbitol level that could distinguish susceptible and tolerant plants was 0.2 M sorbitol and at this concentration, the characteristics that showed significant interactions were plant height and root length, so that both characteristics could be used as selection indicators for the analysis of tolerance tests for the seven genotypes. The results of tolerance test using the analysis of relative decline and stress-susceptibility index (SSI) showed that PKHT4 and PKHT6 were the genotypes that were tolerant in vitro.

Production Areas

Globally, many crop production areas are threatened by drought and salinity. Potato (Solanum tuberosum L.) is susceptible to these challenging environmental conditions. In this study, an in vitro approach was employed to compare the tolerance of potato cultivars ‘BARI-401’ (red skin) and ‘Spunta’ (yellow skin). To simulate ionic and osmotic stress, MS media was supplemented with lithium chloride (LiCl 20 mM) and mannitol (150 mM). GC-MS and spectrophotometry techniques were used to determine metabolite accumulation. Other biochemical properties, such as total phenols concentration (TPC), total flavonoids concentration (TFC), antioxidant capacity (DPPH free radical scavenging capacity), polyphenol oxidase (PPO), and peroxidase (POD) activities, were also measured. The two cultivars respond differently to ionic and osmotic stress treatments, with Spunta accumulating more defensive metabolites in response, indicating a higher level of tolerance. While further investigation of the physiological and biochemical responses of these varieties to drought and salinity is required, the approach taken in this paper provides useful information prior to open field evaluation.

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.

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.
