Research on some biological indicators of ROC10, ROC23, and ROC26 varieties growing in Hoa Binh province

Analysis of some biochemical indicators during the growth and development of 3 sugarcane varieties ROC10, ROC23, ROC26 is one of the methods contributing to the prequalification of sugarcane varieties with good quality. The results showed that the reducing sugar content in the stems of all three sugarcane varieties decreased with age, of which ROC23 and ROC26 were less than that of ROC10. The sucrose content increased gradually, and ROC23, ROC26 had higher sucrose content than ROC10. The starch content in the cane stem decreased gradually with the age of the plant, of which varieties ROC23, ROC26 were less than ROC10. Vitamin C content of ROC23 variety was higher than that of ROC10 variety in the growing period while ROC26 variety at an early stage, vitamin C content was less than that of ROC10 variety but from 9 months old onwards, it was higher than ROC10 variety. The cellulose content of the ROC23 variety was highest, followed by the ROC10, and the lowest was the ROC26 variety. The results of this study are the scientific basis for selecting sugarcane varieties with good quality based on the biochemical changes of the plant during growth and development.
