Determination of Seed Quality of Dendrocalamus latiflorus Munro by X-ray

Abstract

The objective of this study was to determine seed viability of Dendrocalamus latiflorus by X-ray technique with anatomical potential value. The results indicated that the images of D. latiflorus seeds could be determined by X-radiography and classified into four anatomical seed quality classes. Based on their anatomical developments, the anatomical potential value was highly effective in evaluating seed quality in terms of viability of D. latiflorus. Results of this study revealed no significant differences for the anatomical potential value in class I (19.59 %) and II (13.93 %), while the anatomical potential value which was represented of these two classes was 17.63 %, and in class III and IV were 4.87 % and 0 %, respectively. There was no significant difference for seed viability between standard germination test (10.25 %) and X-ray technique by using the anatomical potential value (11.25 %). However, the direct X-ray test (57.05 %) gave higher in evaluating seed viability than standard seed germination and applied X-ray technique. The results from this study, however, showed that X-ray technique could be effectively used to determine seed viability only for new seedlots. Therefore, special attention should be made when determined seed quality by X-ray technique with high dormancy seedlots or low vigour seedlots.
