چکیده

به‌منظور بررسی اثر تنش شوری بر خصوصیات مورفولوژیکی، جذب و انتقال برخی عناصر غذایی بادام آزمایشی به‏‌‏صورت فاکتوریل در پایه طرح کاملاً تصادفی با دو عامل ترکیب پیوندی و پایه هرکدام در 4 سطح (پایه‌های رویشی GF677،GN15 و تترا و پایه بذری بادام تلخ به‏‌‏عنوان شاهد و پیوند شاهرود-12 بر روی چهار پایه ذکرشده) و عامل شوری آب آبیاری در پنج سطح (۳/۰، 2، 4، 6 و 8 دسی‌زیمنس‌ بر متر)، صورت گرفت. نتایج نشان داد افزایش شوری تا 8 دسی‌زیمنس بر متر سبب کاهش نیتروژن برگی رقم شاهرود-12 در حالت پیوندی و پایه‌های غیر‌پیوندی شد. با افزایش شوری تا 8 دسی‌زیمنس بر متر، بیشترین و کمترین کاهش در مقدار فسفر برگی نیز به‌ترتیب در پایه شاهد (غیر پیوندی) GF677 و رقم شاهرود-12 پیوندشده بر پایه GF667 مشاهده شد. افزایش میزان شوری منجر به افزایش مقدار پتاسیم برگی رقم شاهرود-12 پیوندشده بر پایه GF677 و پایه شاهد GF677 گردید. با افزایش شوری نسبت سدیم/ نیتروژن در ریشه پایه‌های شاهد افزایش یافت. در شوری 8 دسی‌زیمنس، بیشترین و کمترین نسبت سدیم/پتاسیم نیز به­ترتیب در پایه شاهد بادام تلخ بذری و شاهرود-12 پیوندشده روی پایه GF677 مشاهده شد. نتایج نشان داد ترکیب شاهرود-12 پیوندشده بر روی GF677 متحمل‌ترین ترکیب به شوری بود.

چکیده [English]

In order to study the effect of salinity stress on morphological characteristics, absorption and transport of some nutrients of almond, a factorial experiment based on a completely randomized design with two factors including rootstock and rootstock and scion combination in four levels(vegetative rootstocks: GF677, GN15, and tetra and seedling rootstock of bitter almond as control and Shahrood-12 on four mentioned rootstocks) and salinity of irrigation water in five levels (0.3(control), 2, 4, 6 and 8 dS/m) were used. The results showed that increasing salinity up to 8 dS/m reduced the leaf nitrogen content of Shahroud-12 cultivar in grafted form and non-grafted rootstocks. With increasing salinity up to 8 dS/m, the highest and lowest reduction in leaf phosphorus content were observed on the control (non-grafted) GF677 and Shahroud-12 cultivars on GF667, respectively. Increasing salinity resulted in increased potassium content of Shahroud-12 on GF677 and non-grafted GF677 rootstock. The results also showed that with increasing salinity, the ratio of sodium/nitrogen in the root of the control rootstocks increased. In salinity of 8 dS/m the highest and lowest sodium/potassium ratio was observed in the seedling rootstock of bitter almond and Shahroud-12 on GF677 rootstock. The results showed that Shahroud-12 grafted onto GF677 was the most tolerance compound to salinity.
