Abstract:

To clarify factors influencing differences in calcium content of the big fruit type and small fruit type wild Cerasus humilis, the vessel elements structure characteristics of their roots and stems were studied by a Scanning Electron Microscope (SEM). Moreover, the calcium content of two type's fruits at different fruit development stage (young stage, maturity stage, hardening stage) was determined. The results indicated that the secondary xylem vessel elements of two types C.humilis were both pitted vessel, simple perforation, with two or one or no tails in both end walls. Compared with big fruit type, the distribution frequency of vessel elements with two tails in both end walls in small fruit type was lower, the vessel elements without tails in both end walls was more, and the vessel was wider than big fruit type. The fruit calcium content and water percentage of small fruit type were higher. The vessel element structure characteristics may have some relation with the calcium content in the two types fruits.

Key words: Cerasus humilis, root system, stem system, vessel element, fruit Ca
