[ 1 ] - ارزیابی عملکرد رویشی و تولید در نهال‌های یک‌ساله‌ی هفت گونه از خانواده‌ی Salicaceae (مطالعه‌ی موردی: ایستگاه تحقیقاتی چمستان نور)

     Poplars have long been considered for wood production in various uses and cultivated by the villagers. Willows have also been developed in recent years as biomass and bioenergy sources in the world. The necessity of research on the adaptation of poplars in different planting conditions is important for achieving superior clones. In this study the growth and production function of Salix exc...

[ 2 ] - Study of Growth Function of Black Poplar (Populus Nigra) With Kermanshah and Zanjan Origin in Karaj Research Station

In order to evaluate the growth function of Populus nigra trees under homogeneous conditions, a total of 24 individuals of P. nigra (3 individuals per stand) were sampled from 8 artificial stands in Kermanshah province and 12 individuals of P. nigra (3 individuals per stand) were sampled from 4 artificial stands in Zanjan province.

[ 3 ] - Estimation of stem biomass of Pupulus. caspica and Pupulus. alba 57.58 seedlings based on allometric relations (Case study: Chamestan, Noor)

Today, the use of allometric relations for easy, non-destructive, low cost and fast estimation of tree biomass is widely used. The aim of this study was to estimate the stem biomass of Pupulus. caspica and Pupulus. alba 57.58 seedlings. First, 45 cuttings from both fast-growing tree species were selected and planted in a randomized complete block design with three replications in the lands of C...
