Abstract

Banana (Musa sp. - ABB) cv. Kepok is one of type banana processed that have a very potential commodities fruit developed to support food survival. The purpose of this study was to knowing the effect of gamma irradiation on the growth of banana plants cv. Kepok in vitro. This study was conducted in October 2014 – October 2015 in Plant Tissue Culture Laboratory, Biological – Science UNJ. The methods used was experiment with fully randomized design. Factors that tested was 6 gamma irradiation doses (0, 20, 30, 40, 50, 60 Gy) with 10 repetition. Observation of phenotypic generate diverse characters on the growth of the number of shoots and leaves. Gamma irradiation dose of 50 Gy is doses most inhibits the growth of character. Mutations that occur in banana plantlets cv. Kepok generated by the treatment doses gamma irradiation induced mutation is random.

Abstract

Developing of jewawut cultivation as an alternative source of carbohydrates is one of the efforts to prevent food insecurity. Drought conditions and the availability of drought-tolerant seeds became one of the problems in the development of jewawut cultivation. The purpose of these experiments were to evaluate jewawut response to drought stress simulations at germination phases and to obtain accessions tolerant to drought stress. Drought stress is performed indirectly (PEG 6000 selective media). The research was done in Laboratory of Physiology of Faculty of Mathematic and Science, UNJ from February until July 2017. The experiments were done with a completely randomized design. Parameters of germination were analyzed with Anova test and continued by Duncan Multiple Range Test (DMRT). Lethal doses of PEG reducing 50% of germination (LD50) were 23,25%, with the quadratic equation y = 1,12-2,72x. The results base on germination phase, Buru merah as drought tolerance accessions, Polman merah and Polman kuning as medium tolerance accession, and Buru kuning as susceptible accessions.

Abstract

Nilam (Pogostemon cablin Benth.) merupakan tanaman semak penghasil minyak atsiri yang memiliki nilai ekonomi yang tinggi. Budidaya tanaman nilam memiliki kendala yaitu adanya serangan kapang Synchytrium pogostemonis penyebab penyakit budok. Tujuan dari penelitian ini adalah untuk mengetahui ketahanan 3 varietas nilam terhadap penyakit budok, dan mengetahui efektivitas dari formula tunggal dan campuran minyak mimba dan seraiwangi terhadap kejadian penyakit budok dan pengaruhnya pada pertumbuhan tanaman. Penelitian ini terdiri dari dua percobaan: 1) Efektivitas metode infeksi dan uji ketahanan tiga varietas nilam terhadap penyakit budok di rumah kaca, dan 2) Uji efektivitas minyak atsiri formula tunggal maupun campuran mimba dan seraiwangi sebagai pestisida nabati terhadap penyakit budok. Hasil percobaan efektivitas metode infeksi menujukkan bahwa metode perendaman akar tanaman dalam inokulum budok selama satu jam lebih efektif menginfeksi penyakit budok dibandingkan dengan metode penyiraman ke media tanam. Hasil uji ketahanan nilam varietas Sidikalang, Patchoulina 1 dan Patchoulina 2 menunjukkan bahwa varietas Patchoulina 1 lebih rentan terhadap penyakit budok karena menimbulkan keterjadian penyakit (KeP) dan keparahan penyakit (KP) hingga 20%, dengan karekter pertumbuhan tinggi tanaman yang lebih rendah dibandingkan varietas lain yang diuji. Sedangkan diantara minyak atsiri yang diujikan, formula minyak atsiri campuran (mimba dan seraiwangi) konsentrasi 0.5% lebih efektif dalam mengurangi penyakit budok, namun efektivitasnya masih lebih rendah dibandingkan dengan perlakuan fungisida benomil 0,3% dan bubur bordo 0,1%. Aplikasi formula minyak atsiri secara signifikan tidak berpengaruh negatif terhadap pertumbuhan nilam, sehingga formula campuran (mimba dan seraiwangi) 0,5% dapat digunakan untuk mengontrol penyakit budok pada tanaman nilam.

Abstract

Abstract Plants resistance to Fusarium wilt can be developed by mutation breeding and in vitro selection techniques. The objectives of this research were to evaluated growth and development of banana plantlets cv. Ampyang (Musa acuminata, AAA) resistance to Fusarium wilt. The plant material used in this study was 9 (nine) code clones banana cv. Ampyang result from mutations induced by gamma irradiation (30, 45, and 50 Gy) and in vitro - in vivo selection, a collection of Plant Tissue Culture Laboratory Department of Biology UNJ. Plantlets multiplied for four months on Murashige and Skoog supplemented with2.25 mgL-1 Benzyl amino purine and 0.22 mgL-1 Thydiazuron and 0.175 mgL-1 Indole 3 acetyc-acid . Acclimatization and evaluation of plantlet growth and development in a greenhouse showed that percentage of survival rate of plantlet were ranging from 42.9 – 100%. There was phenotypic variation among those plantlet investigated in quantitative and qualitative character. Plantlet regenerated from clone A regenerated from gamma irradiation 30 Gy and after in vitro selection of Foc from isolate Medan showed significantly the highest number of leave and fresh weight. The less number of roots length and other phenotypic character were produced from clone B, D and F. All of the regenerated plantlets were successfully transferred into soil and they would be used to evaluate the existence of variants in a greenhouse. Keywords: phenotypic variation, induce mutation and in vitro selection, shoot multiplication, Foc isolates from Medan
