چکیده

به­منظور بررسی تأثیر نانوچندسازة (کامپوزیت) حاوی نانوذرات زئولیت و برخی عنصرهای غذایی بر ویژگی­های رشدی گل بنفشۀ آفریقایی، آزمایشی به­صورت فاکتوریل در قالب طرح کامل تصادفی با سه تکرار در دانشکدۀ کشاورزی دانشگاه اراک در سال 1394 انجام گرفت. بنفشۀ آفریقایی (Saintpaulia inonatha Wendl) در کنار محبوبیتی که به­­عنوان گیاه گلدانی در جهان دارد، به نوع آبیاری حساسیت بالایی دارد. تماس مداوم آب با اندام­های گیاه باعث پوسیدگی و پدیدار شدن لکه­های سفید و زرد روی برگ­ها می‌شود. در این تحقیق تأثیر کاربرد نانوچندسازة حاوی نانوذرات زئولیت و برخی عنصرهای غذایی (نیتروژن‏، فسفر و پتاسیم) در چهار سطح (0، 1، 2 و 3 گرم در هر گلدان) و سه دور آبیاری (5، 10 و 15 روزه) ‏بر برخی شاخص­های ریخت‌شناختی (مورفولوژیکی) و فیزیولوژیکی بنفشۀ آفریقایی بررسی شد. نتایج نشان داد که نانوچندسازة مورد استفاده به­ویژه در بیشترین میزان به­کاررفته (3 گرم در هر گلدان) افزون بر کاهش تأثیر منفی کم­آبیاری‏، باعث افزایش چند برابری جذب عنصرهای فسفر و پتاسیم در تیمارهای حاوی آن‌ها شد. همچنین افزایش معنی­دار ویژگی­های ریخت‌شناختی (مانند طول و عرض برگ­ها، تاج‌پوشش (کانوپی) و وزن تر) و کاهش برخی ویژگی­های فیزیولوژیکی مانند نشت یونی مشاهده شد.

چکیده [English]

A factorial experiment in completely randomized design with three replications was conducted to investigate the effects of nanocomposite containing zeolite nanoparticles and some nutrients on the growth characteristics of African violets. This experiment was run in Agriculture and Natural Resources College, Arak University, in 2015. African violet (Saintpaulia ionantha) as a potted plant is sensitive to the method of irrigation. Water continuous contact to plant organs may be caused to rot the plant and appearance of white and yellow spots on leaves. The effect of Nanocomposite containing zeolite nanoparticles plus nutrients (nitrogen, phosphorus and potassium) in four levels 0, 1, 2 and 3 grams per pot) and three irrigation intervals (5, 10 and 15 days) on some morphological and physiological characteristics of African violet were investigated in this study. The results showed that nanocomposites in the highest level (three gram per pot) in addition to reducing the negative effects of deficit irrigation, increased the multiple absorption of phosphorus and potassium. Furthermore, increasing the morphological traits (length and width leaves, canopy, fresh weight and chlorophyll index) and decreasing of some physiological characteristics such as ion leakage, were observed, significantly.
