四爪陆龟生长的研究——Ⅱ.四爪陆龟形体生长的初步分析

Studies on the Growth of Testudo horsfieldi Ⅱ.Preliminary Analysis of Morphometry

本文对野生状态下生活的46只四爪陆龟的背板长度、背板宽度、壳高和腹板长度测量数据的分析研究表明,在四爪陆龟形体生长中,背板长度的增长速率基本上与腹板长度的增长速率相同,并具较高的相关性,背板宽度的增长速率高于壳高的增长速率,因此四爪陆龟龟壳显得较为平坦,计算结果表明,四爪陆龟背板长度与腹板长度的形体生长方程为:y=0.93x′+0.10,背板宽度与腹板长度的形态生长方程为y′=1.08x′-0.14,壳高与腹板长度的形体生长方程为:y′=0.88x′+0.46.

A study of the growth of the shell was conducted on forty-six Testudo horsfieldi. Straightlines in carapace length, carapace width and shell height increase approximately atthe same rate as the straight line in plastron length and are highly correlated toplastron length.
