Hence, flour of cellulosic shell of Pistachio, in levels of 30, 40 and 50 and Nano clay of cloisite 15A in three levels (0, ...  Read More
Comparative study of chemical components and morphological features of trunk and cone fibers from loblolly pine grown in Gilan province

Tahereh gholizadeh; Arash Farajpour Roudsari; Asghar Tabei

Volume 28, Issue 3 , October 2013, , Pages 545-560

https://doi.org/10.22092/ijwpr.2013.3462

Abstract
  The purpose of this study was to compare the chemical compositions and biometric features of stem and cone fibers (length, diameter, and wall thickness) and the derived coefficients of loblolly pine (Pinus taeda) in Astara district, Gilan province. Discs from stem and cone were randomly taken and the ...  Read More
