Abstract

The aims of this research were to identify the effect of concentration growth regulator IAA and BAP as the basic MS medium against multiplication of banana plants by in vitro. The experiment  was   carried  out  at   Laboratory  of   Biotechnology,  Faculty  of Agriculture, University of Sultan Ageng Tirtayasa from November 2013 to May 2014. The experiment used Completely Randomized Design which arranged in with two factors. The first factor was the concentration of growth regulators IAA which consisted of 4 levels (0 mg/L, 0.1 mg/L, 0.2 mg/L, 0.3 mg/L). The second factor was growth regulator BAP which consisted of 4 levels (0 mg/L.2 mg/L, l.4 mg/L, 1.6 mg/L), so that there were 16 treatment combinations, and repeated 3 times. The variables observed were number of shoots and growing percentage of the plant. The results showed that there was significantly interaction in number of shoot in 3 WAP. The best treatment was I1B1 (IAA 0,1 mg/L dan BAP 2 mg/L) for the number of shoot in 5 WAP. Keywords: IAA, BAP, Banana, Multiplication

Abstract

This research was aimed to know the effect of magnetic field strenght and duration of Immersion on Germination of ExpiredRice (Oryza sativa L.) Seed of Ciherang Variety. This research used a Randomized Complete Design with two factors. The first factor was magnetic field strenght (M) consisting of four levels, namely: M0 (0 mT), M1 (15 mT), M2 (20 mT) and M3 (25 mT). The second factor was duration immersion in magnetized water (T), which consists of three levels, namely: T1 (12 hours), T2 (24 hours) and T3 (36 hours). The combination treatment was repeated three times, so there was 36 experimental units. Observed variables were germination age (days), the maximum growth potential (%), growth rate (%/day), normal germination percentage (%) and abnormal germination percentage (%). The result showed that magnetic field strenght and magnetized water is not able to improved for all observed variables were germination age (days), maximum growth potential (%), growth rate (%/day), normal germination percentage (%) and abnormal germination percentage (%). There was an interaction between the magnetic field strenght and duration of immersion time. The interaction magnetic field strenght of 0 mT and 15 mT with 12 hours and 20 mT with 24 hours immersion. Improved the growth rate and normal germination percentage by 0,95 %/day and 13,33% consecutively.

Abstract

The study aims to determine the effect of the magnetic field strength and the duration of magnetized water on germination of 2 year old Tanggamus of expired soybean seeds. The study was carried out in a closed room with the temperature used was 16°C-20°C in Desember 2015 to January 2016. The study was compiled using a completely randomized factorial design with 2 factor. The first factor is the magnetic field strength which consist of 4 level M0 (the magnetic field strength of solenoid 0mT), M1 (the magnetic field strength of solenoid 1mT), M2 (the magnetic field strength of solenoid 2mT), M3 (the magnetic field strength of solenoid 3mT). The second factor is the duration of magnetized water which consists of 3 level T1 (the 18 hour duration of magnetized water), T2 (the 24 hour duration of magnetized water), T3 (the 36 hour duration of magnetized water). The treatment was repeated 3 times so that there are 36 units of observed variables experiment such as the germination age the potential of growth, the maximum speed of growth, the normal percentage of germination, the abnormal percentage of germination, the abnormal percentage of germination. The solenoid magnetic field treatment level 2 mT gave a very real influence on the parameters of the age of maximum growth potential, the growth rate, the percentage of normal seedliry of 6 month old and 2 year old expired soybean seeds. The treatments of soaking seeds with 24 hour duration of magnetized water produced the best developments on the 6 month old and 2 year old expired seeds even though there are differences in same of the best results in the observation parameter of both of the expired speeds. The best level treatment of 6 month old expired seed is the interaction of M2T2 level (the magnetic field strength 2mT and the duration of 24 hour magnetized water) which provided the best result to the parameter of maximum growth potential, percentage of normal germination, and percentage of abnormal germination. While the best level treatment of 2 year old expired seed is the interaction of M2T3 level (the magnetic field strength 2mT and the duration of 36 hour magnetized water) which provided the best result to the parameter of germination age, speed of growth and percentage normal germination.Key words : magnetized, solenoid, expiry, germination, soybean, seeds
