The correlation between PtVg4 expression level and Vg concentration in tissues (midgut glands, ovaries and hemolymph) and the time of tissue collection in various experimental groups that were treated with 20E, fenoxycarb and precocene I at different doses
The scale of the assessment of the correlation the r values: 0.2–0.4 – weak, 0.4–07 – average, 0.7–0.9 – strong, 0.9–1 – very strong
x – no analysis,
empty fields – no statistically significant correlation
