Correlation between Larvae Mass and Silk Glands Mass of Silkworm Bred in Transylvania
Abstract
Seven breeds and eight hybrids of silkworm Bombyx mori L. bred in Transylvania were subjected to this study of correlation between larvae mass and silk glands mass, taking into account the fact that there is a correlation in the development of the larvae and the silk gland’s mass from which the silk thread results. At the end of the fifth instar were performed measurements of larvae mass on a number of 20 individuals from each breeds and hybrids, after that silk glands were extracted with dissection kit and their mass determined by weighing with electronic balance Partner XA110. Coefficient used for determination (R2) indicates a positive correlation between larvae mass and silk gland mass of larvae taken in the study and proves a inter-reciprocal influence of both characters.
