چکیده

درختان صنوبر درختانی چوبده هستند که رقم‌های مختلف آن علاوه‌بر توان متفاوت تولید چوب، از نیازهای غیریکسانی برخوردارند. مقدار آب و دوره های دسترسی به آب باعث تغییرات بسیاری در رقم‌های مختلف صنوبر می‌شود. با توجه به محدودیت آبی مناطق مختلف کشور ضرورت دارد تا وضعیت کمی و کیفی رویش رقم‌های مختلف صنوبر در رژیم‌های آبیاری مختلف بررسی شود و برای گونه‌ها و مناطق اقلیمی مختلف تأثیر آن سنجیده شود. از سوی دیگر، درختان در سنین مختلف نیازهای متفاوتی دارند. بنابراین در این بررسی، نه رقم از رقم‌های برگزیده و برتر منطقه کرج در قالب طرح کرت‌های خردشده  با سه تکرار در دو سطح آبیاری چهار و هشت‌روزه برای یک دوره ده ساله مورد مطالعه قرار گرفتند. براساس نتایج مشخص شد که ضمن اینکه در تیمار چهارروزه سالانه 4500 مترمکعب آب بیشتری در مقایسه با تیمار هشت‌روزه مصرف شده است، رویش قطری مجموعه کلن‌ها در دو تیمار تفاوت معنی‌داری دارند، اما رویش ارتفاعی و تولید حجمی صنوبرهای دو تیمار تفاوت معنی‌داری را نشان ندادند. همچنین  کلن P.e.561/41 به‌تنهایی به‌شدت متأثر از مقدار متفاوت آب دو تکرار بود و حجم چوب تولیدی تیمار چهارروزه بسیار بیشتر از تیمار هشت‌روزه بود. کلن‌های P.e.561/41 و P.e.vernirubensis  به‌همراه دو کلن P.n.62/154 و P.n.betulifolia از بهترین تولید حجمی و رویش قطری و ارتفاعی برخوردار بودند.

چکیده [English]

Poplars are associated with variations in the yield which are influenced by their variable requirements. Due to restrictions in water availability across the country as caused by long-lasting drought periods, the amount and duration of irrigation has been continuously changed. Thus, the qualitative and quantitative growth properties of poplar cultivars is necessary be quantified in association with different irrigation regimes. Furthermore, seedlings and mature trees have different requirements. Therefore, we carried out a survey in Karaj to study 9 species of selected cultivars in a split plot design with 3 replications which we treated with two 4-day and 8-day irrigation regimes. For each treatment, the incoming water were measured by installing WSC flume type 3 which was used to determine section levels and timing of water through the flume by using standard curves for each flume. Data analysis resulted in significant differences observed amongst diameter growth of the clones. However, height volume growth did not show any significant difference between two treatments. The 4-day treatment spent 4500 m3 year-1 water more than the 8-day treatment. The P.e.561/41 clones were strongly affected by varying amounts of water, and the volume of produced wood from 4-day treatment was substantially higher than that of 8-day treatment. The P.e.561/41, P.e.vernirubensis, P.n.62/154 and P.n.betulifolia clones were concluded to excess other investigated clones in volume, diameter and height growth.
