Fig. 4

Monthly variations in lipid index (LI) and protein index (PI) in oocytes of Trophon geversianus. a LI annual variation (mean ± SE, n = 4–5). Significant differences in LI between months are indicated with different symbols (Asterisks, filled diamonds). b PI annual variation (mean ± SE, n = 3–4). No significant differences were found in PI between months
