A study was carried out to investigate the effect of growth regular on protein content, PAL and peroxidase activity in rice seedling plants, Akibare, a Japonica type variety. ABA(0.1, 1, 10ppm), 2.4-D(10, 100, 1000ppm), and GA(0.05, 0.5, 5ppm) were re...
A study was carried out to investigate the effect of growth regular on protein content, PAL and peroxidase activity in rice seedling plants, Akibare, a Japonica type variety. ABA(0.1, 1, 10ppm), 2.4-D(10, 100, 1000ppm), and GA(0.05, 0.5, 5ppm) were respectively treated for 5 days to the nee seedling plants which were grown for 20 days. The results were summarized as follows.
In stems, the protein content showed the highest value in the plot treated with GA for 5 days, although ABA and 2.4-D treated plots showed no significant differences compared with the control. PAL activity in the plot treated with GA for 5 days and in the plot treated with 2.4-D for 10 days were respectively higher than control. On the contrary, it was low in the plot treated with ABA. PAL activity in roots was respectively higher in the plots treated with GA for 5days and 2.4-D for 10 darts than the control. According to increment of days seedling growth, peroxidase activity was respectively maintained in the plot treated with ABA, 2.4-D, and GA, although it was decreased in the control.
