Table 3 Results of statistical analyses (t-test or Mann-Whitney rank sum test) of the length and diameter of stalks between successive developmental stages. Stalks were not present during the developmental stages 1 and 2. d. f., degrees of freedom; No, no significant difference; P, probability value; t, t-test statistics; T, Mann-Whitney rank sum test statistics; Yes, significantly different
Comparison | Normality test | Equal variance test | d. f. | Test statistics | P | Significantly different |
|---|---|---|---|---|---|---|
