Qobiq cho'ntak

Po'stloq cho'ntaklar - bu daraxtning yog'ochiga qisman yoki to'liq singib ketgan yamoqlar yoki po'stloq qo'shimchalari. Ular biomonitor sifatida ham ishlatilishi mumkin. Qobiq cho'ntaklar yog'och sanoatida noqulay boʼladi, chunki ular nuqson deb hisoblanadi va yogʼochning sifatini pasaytiradi.^[1] Po'stloq cho'ntaklar, shuningdek, daraxt vilkalarini zaiflashtirishi mumkin va stress ostida birikmaning shikastlanishiga olib kelishi mumkin.^[2]

Shakllanish

Po'stloq cho'ntaklari emlash, daraxt vilkasini shakllantirish, novdani inkapsulyatsiya qilish, notekis qismlarini birlashtirish yoki boshqa ob'ektni yopish orqali hosil bo'lishi mumkin.^[3]^[4] Emlash paytida, ikkita birlashuvchi magistral orasiga tiqilib qolgan po'stloq tanasi birlashgandan so'ng, yog'och bilan o'ralgan bo'ladi. Emlash paytida yoki daraxt vilkalarida hosil bo'lgan po'stloq cho'ntagiga qo'shilgan qobiq deyiladi.

Filial kapsulalanganda, novdaning tashqi qobig'i daraxtning yog'och ichida qolishi mumkin, chunki qismlari kengayadi va shox atrofida o'sadi.
