Monoromachanu1* and PY - 2011/08/25 Y2 - 2025/09/23 TI - Studies on Hydrogen-ion-concentration in Tasar Silkworm (Antheraea proylei Jolly) JF - Journal of Experimental Sciences JA - JES VL - 2 IS - 9 SE - Life Sciences DO - UR - https://www.updatepublishing.com/journal/index.php/jes/article/view/1873 SP - AB - <p class="MsoNormal" style="margin: 6pt 0in 0pt; text-align: justify;"><span style="font-size: 10pt; font-family: ";Arial Narrow";,";sans-serif";;">Silk is a proteinaceousfibresynthesised by the silkworms from a specialized organ known as silkglands which are nothing but the modified labial glands of certain lepidopteran insects. The hydrogen- ion concentration in the larval haemolymph, silkgland and food leaves of <strong style="mso-bidi-font-weight: normal;"><em style="mso-bidi-font-style: normal;">Antheraea proylei</em></strong> has been determined by <strong style="mso-bidi-font-weight: normal;">“ Indicator paper technique” </strong>and<strong style="mso-bidi-font-weight: normal;">“ Universal indicator technique”</strong>. The pH of larval haemolymph and silk gland has been found in range 6.0-6.5 each and 5.5-6.2 in the food leaves. The mean values of haemolymph, silkgland and food leaves have been calculated to be 6.3±0.0596, 6.21±0.0586 and 5.88±0.0772 respectively. The multiple correlation co-efficient of silkgland on haemolymphand food has been found to be R²=93.6% and significant at 1% level.</span></p> ER -
