چکیده

به‌منظور دسترسی به مناسب‌ترین کلن‌های صنوبر با هدف توسعۀ فعالیت‌های زراعت چوب در مناطق جلگه‌ای استان گیلان، 12 کلن مختلف صنوبر از گروه‌های اورامریکن، دلتوئیدس و دو رگ در نهالستان (نهال‌های یک‌ساله) و عرصۀ صنوبرکاری (درختان سه‌ساله) در قالب طرح بلوک‌های کامل تصادفی با 3 تکرار در سال 1397 در ایستگاه تحقیقات زراعی لشت‌نشای گیلان بررسی شد. در پایان دورۀ رویش، درصد زنده‌مانی، قطر یقه و ارتفاع نهال‌های یک‌ساله در نهالستان و همچنین درصد زنده‌مانی، قطر برابرسینه و ارتفاع درختان سه‌ساله در عرصۀ صنوبرکاری اندازه‌گیری شدند. تجزیۀ واریانس داده‌های به‌دست‌آمده از درصد زنده‌مانی، قطر و ارتفاع کلن‌های مختلف تحت بررسی نشان داد که بین درصد زنده‌مانی درختان سه‌ساله و قطر نهال‌های یک‌ساله در کلن‌های بررسی‌شده تفاوت معنی‌داری وجود ندارد، اما بین درصد زنده‌مانی و ارتفاع نهال‌های یک‌ساله و همچنین قطر و ارتفاع درختان سه‌ساله در کلن‌های تحت بررسی تفاوت معنی‌داری مشاهده شد. بدین ترتیب کلن‌هایP. deltoides Marquette ، P. deltoides 92/258، P.eur. Blanc du poitou و P. deltoides 92/160 در یک گروه دارای بیش­ترین و کلن P. x. 87m.119 دارای کم­ترین زنده‌مانی و کلن‌های P. deltoides Marquette و P. deltoides 92/258 به‌ترتیب دارای بیش­ترین و کم­ترین رویش ارتفاعی در نهالستان بودند. همچنین بررسی قطر برابرسینه و ارتفاع درختان سه‌ساله نشان داد که کلن‌های P. deltoides 92/258 وP.eur.I-Sieres به‌ترتیب بیش­ترین و کم­ترین قطر را داشتند ضمن آنکه کلن P. deltoides 92/258 از نظر ارتفاع در مقایسه با دیگر کلن‌ها از موقعیت برتری برخوردار بود، کلن P.eur. Blanc du poitou از نظر رشد ارتفاعی قابل رقابت با کلن‌های دیگر نبود.

چکیده [English]

In order to access the most suitable poplar clones for the purpose of expanding wood farming activities in the lowland areas of Guilan province, twelve different poplar clones from euramericana, deltoides and hybrid poplars were studied in nursery (annual seedlings) and poplar plantation (three-year-old trees). This study was carried out in a Randomized Complete Block Design with three replications at Fakhr Abad research station in 2019. Survival percentage, diameter and height of one-year-old seedlings in nursery as well as survival percentage, diameter at breast height and height of three-year-old trees in poplar plantation were measured at the end of the growing season. Analysis of variance of data obtained from survival percentage, diameter and height of different studied poplar clones showed that there was no significant difference between survival rate of three-year-old trees and diameter of one-year-old seedlings, but there was a significant difference between survival rate and height of one-year-old seedlings and diameter and height of three-year-old trees. Thus P. deltoides Marquette, P. deltoides 92/258, P.eur. Blanc de poitou and P. deltoides 92/160 clones in a group with the highest and P. x. 87m.119 had the lowest survival rate, and P. deltoides Marquette and P. deltoides 92/258 clones had the highest and lowest height growth in nursery, respectively. Also, the study of diameter at breast height and height of three-year-old trees showed that P. deltoides 92/258 and P.eur. I-Sieres had the highest and the lowest diameters, respectively. P.eur. Blanc de poitou clone was not competitive with other clones in height.
