Abstract

The objective of this research was to know whether citric acid was able to decrease effect of aluminum on the seedling growth of soybean (Glycine max L.) varietas anjasmoro.   The experiment was conducted in Plant Physiology Laboratory, Department of Biology, Faculty of Mathematic and Natural Science, Lampung University on January 2016 in 2x3 factorial designs. Factor A was aluminum with 2 levels : 0 mM and 5 mM.  Factor B was citric acid with 3 levels : 0 mM, 5 mM and 10 mM.  Variables in this research were fress weight, dry weight, relative water content and total chlorophyll content.   Analysis of variance was conducted  at  5% significant  level.    If  interaction  was  not  significant,  main  effect  was determined with lsd test at 5% significant  level. If interaction was significant simple effect was determined with F test at 5% significant level.  The result showed that the citric acid decreased fress weight, dry weight, relative water content and no effect on total chlorophyll content while aluminum did not affect all variables and no interaction between citric acid and aluminum on all variables. It is concluded that citric acid was not able to inprove seedling growth of soybean varietas anjasmoro with aluminum or no aluminum. Keyword : Citric acid, Aluminum,  Soybean, Frees weight , dry weight

Abstract

The objective of this research was to know whether soaking of upland rice seed in citric acid solution  could  alleviate  subsequent  growth  of  seedling  under  aluminum  stress.  The experiment was conducted in plant physiologylaboratory, Department of Biology, Faculty of Mathematic and Natural Science, Lampung University on January 2016, and implemented in2 x 3 factorial designs. Factor A was aluminum with two levels: 0 mM, 5 mM and factor B was Citric Acid with three levels: 0Mm, 5Mm, 10Mm. Variables in this research were shoot length, seedling fresh weight, relative water content, and shoot root ratio. Analysis of variance was conducted at 5% significant level. If   interaction factor A and B was not significant, main effect was determine with lsd test at 5% significant level, but if  significant simple effect was determine with F test at 5% significant level. The result showed that interaction beetwen aluminum and citric acid decreased the shoot length 16-31%. Aluminum decreased fresh weight of seedling 11%, relative water content 3%, and shoot root ratio decreased 15%. It was concluded that soaking upland rice seed in citric acid solution was not able to alleviate subsequent growth of seedling under aluminum stress. Keyword: citric acid, aluminum, upland rice, shoot length, seedling fresh weight
