Comparison of the character of vessel elements in secondary xylem among three peach rootstocks in China
Abstract：To provide a basis for the selection of peach cold-resistant rootstock, the shape and size of vessel elements in root and stem from three typical peach rootstocks, Prunus davidiana （SP）, P. persica （MP） and Prunus persica cv. Hun-chun-tao （HP）, were examined using tissue segregation procedure, micrograph and biometric statistical method. The results showed that there were no obvious differences in the mode of secondary wall thickening and lignifications, pitting pattern, and types of perforation plates in both of root and stem among all three rootstocks, and the proportion of vessel element with one tail in all three roots and spiral thickening phenomenon in all three stems were similar. However, the proportions of vessel element without tail, with two tails, one tail, two slantwise end walls, one slantwise end wall, two horizontal end walls, the length and diameter of vessel element, and the length and diameter ratio of vessel element were different in root and stem among the three peach rootstocks.
