N2  - Doğu ladini (Picea orientalis L.) geçirgenliği düşük olan ağaç türlerinden bir tanesidir. Bu çalışmada doğu ladini diri odun örnekleri enzimatik muameleye uğratılarak, geçirgenliği arttırılmaya çalışılmıştır. Geçit membranları, komşu hücreler arasındaki su iletiminin gerçekleştirilmesinde önemli bir rol üstlenmektedir. Doğu ladini geçitleri, lif doygunluk noktası altındaki rutubetlerde kapanmaya meyillidir. Bu durum odundaki sıvı iletimini engelleyerek, emprenye işlemini zorlaştırmaktadır. Geçitler selüloz, hemiselüloz, lignin, pektin ve fenolik bileşiklerden oluşmaktadır. Torusun yüzeyini pektin maddesi kaplamaktadır. Bioprep 3000 L, Viscozyme L, Texazym BFE, Texazym DLG enzimleri tekstil endüstrisinde, lignoselülozik materyalin uzaklaştırılmasında yaygın olarak kullanılan enzimlerdir. Enzimatik muamele ile kapalı geçitlerin yapısı tahrip edilerek açılması hedeflenmiştir. Çalışmanın sonucunda, enzimatik muamele ile ladin odununun retensiyon ve penetrasyon derinliği değerlerinde artışlar elde edilmiştir. Farklı karışımlarından oluşan enzimler ile muamele edilen örneklerin retensiyon ve penetrasyon değerlerinde daha fazla artış meydana gelmiştir.
