Daftar Isi:
- The research aims were 1) to study the effects of B and Si to the structure strength of root epidermis tissue and growth of banana (Musa) �Ambon Kuning�, 2) to determine whether there were any interaction effects between B and Si on the structure strength of root epidermis tissue and growth of banana (Musa) �Ambon Kuning�, and 3) to determine the optimal doses of B and Si that induce structure strength of root epidermis tissue and growth of banana (Musa) �Ambon Kuning�. The research was arranged in Randomized Complete Block Design (RCBD) factorial 5 x 3 with three blocks as replication. The first factor was doses of B, namely 0, 1.75, 3.5, 5.25 and 7 g/plant. The second factor was doses of Si, namely 0, 1.151, 2.301, 3.452 and 4.602 g/plant. The observations were done on physiological activities, growth and structure reinforcement of root epidermis tissue. Data were analyzed using analysis of variance (ANOVA) at 5% level, continued with Duncan's Multiple Range Test (DMRT) if there were significant differences among the treatments. The relationship patterns between B and Si uptake with physiological activities, growth and structure reinforcement of root epidermis tissue were determined using regression analysis. The results showed that there were no interaction effects between B and Si on the growth, physiological activities, and structure strength of root epidermis tissue of banana (Musa) �Ambon Kuning�. Increasing doses of B up to 7 g/plant inhibit the physiological activities and growth of banana (Musa) �Ambon Kuning� due to the emergence of B toxicity effects. Boron toxicity effects were induced by the increase of B availability in the media, exceeds the optimal range of B. The Si was not optimally absorbed by the banana (Musa) �Ambon Kuning�, allegedly Si dose was too low so it does not affect the absorption of Si and physiological activities as well as corms firmness of banana (Musa) �Ambon Kuning�.
