| چکیده | ||
| هدف از انجام آزمایش بررسی اثرات تنشهای فشردگی و رطوبت خاک بر رشد و ریشه‌دوانی نهالهای زیتون می‌باشد. آزمایش در شرایط محیطی گلخانه‌ای و گلدانی و در قالب روش آماری فاکتوریل و در طرح پایه کاملاً تصادفی و در سه تکرار به اجرا در آمد که تیمارها شامل دو سطح فشردگی خاک (وزن مخصوص ظاهری 1/3 و 1/6گرم بر سانتیمتر مکعب) و دو دور آبیاری (سه و شش روزه) بودند. از نهالهای بذری رقم زرد زیتون و خاک لوم شنی رسی برای اجرای آزمایش استفاده شد. در پایان آزمایش صفات کمی نهالها شامل زنده‌مانی، طول یا ارتفاع نهال، وزن خشک اندام هوایی و ریشه، و طول کلی سیستم ریشه اندازه‌گیری شدند. تجزیه و تحلیل داده‌ها توسط روشهای آماری تجزیه واریانس و آزمون معنیدار بودن تفاوت میانگینها و بکارگیری نرم‌افزار SPSS9 انجام شد. داده‌ها نشان می‌دهند که تیمارهای آبیاری اثر معنی‌داری بر صفات کمی نهالها نداشتند و تنها فشردگی خاک دارای اثر معنیدار بود. فشردگی خاک برخلاف نتایج اعلام شده توسط سایر محققان، نه تنها اثر منفی نداشت، بلکه موجب افزایش معنیدار وزن خشک و طول کلی ریشه‌ها شد. | ||

| The aim of the trial was to investigate the effects of soil compaction and water stress on olive seedling growth and root development. The trial was carried out under pot and glasshouse condition in 2001 at the NationalBotanical Garden, Tehran. The experimental design was Factorial under completely randomized plots with two factors (compaction and irrigation treatments), two levels and three replicates. There were three pots in each plot. The pots were filled with compacted soil (sandy clay loam) up to 50 cm height at one of the levels (bulk densities of 1.3 [low] and 1.6 [high] g/cm3). Seed propagated seedlings were transplanted into the pots and irrigated under one of the period intervals (three [wet] and six [dry] days). The seedlings were harvested in summer 2002 and their survival and canopy and root parameters, including height, shoot dry weight, root length and root dry weight were measured. The data were analyzed using SPSS Microsoft program and ANOVA and T-test methods. Only compaction had significant effects on root parameters. The high level of compaction not only had negative effects on root development, but it increased root length and dry weight significantly. It could be concluded that although both the compaction and drought stresses did not significantly influence survival, but they significantly affected root development | ||
