The Experimental Investigation of Fibers Dimensions Properties (Biometry) of Eggplant Stalks in West Region of Ghilan

This study was conducted to determine the fiber morphological characteristics of Eggplant stalk’s tissue (Solanummelogena var.esculentum) cultivated in the west region of Ghuilan province (Astara region). For this purpose, 20 stalks of Eggplant were collected from Astara region gardens and 3 stalks were randomly selected from among these stalks. After the fibers separation by Franklin method (1954), fiber dimensions, fiber biometric coefficients and weight percentage of stalk components including bark, core and pits. The results showed no significant difference in fiber dimensions and fiber biometric coefficients between different heights of stalks. Besides, there was no significant difference in percentage of core and percentage of bark at different heights of stalks, while a significant difference was found between percentage of pit at different heights of stalks (p<0.05), showing a decrease in stalks by increasing heights of stalks the pit. The averages of fiber length, fiber diameter, lumen diameter and cell wall thickness for this species were 0.63 mm, 16.23 μm, 7.99 μm, 4.12 μm, respectively. Also, the average of runkel, flexibility and felting Coefficients were calculated as 51, 49 and 40.27, respectively. The weight percentage average of stalk components, including bark, core and pit, from top to the down of stalks were also estimated to be 4.84%, 14.62% and 80.54%, respectively.
