چکیده

 به منظور تعیین اثر پیش­تیمار سیلسیوم بر جوانه­زنی بذر و رشد اولیه گیاهچه ارقام مختلف خربزه در شرایط تنش شوری آزمایشی به صورت فاکتوریل در قالب طرح کاملاً تصادفی با چهار تکرار انجام شد. فاکتور اول شامل شوری کلرید سدیم در سه سطح 0، 75 و 150 میلی­مولار و فاکتور دوم تیمار سیلیسیوم در  سه سطح شاهد، 1 و 2 میلی­مولار بود. صفات مورد اندازه­گیری شامل درصد و سرعت جوانه­زنی، متوسط زمان جوانه­زنی، طول ساقه­چه و ریشه­چه، نسبت طول ریشه­چه به
ساقه­چه، وزن تر ریشه­چه و ساقه­چه بود. تنش شوری (150 میلی­مولار) درصد و سرعت جوانه­زنی، طول ریشه­چه و ساقه­چه را به ترتیب 9، 35، 69 و 71% نسبت به شاهد کاهش داد. کاربرد سیلیسیوم 1 میلی­مولار سرعت جوانه­زنی و طول ریشه­چه و ساقه­چه را به ترتیب 20، 33 و 35% نسبت به شاهد افزایش داد. تحت شرایط تنش شوری بیشترین میزان درصد و سرعت جوانه زنی از  تیمار 1 میلی مولار سیلیسیوم و 75 میلی مولار نمک سدیم حاصل شد. در مجموع، کاربرد سیلیسیوم باعث بهبود خصوصیات جوانه­زنی و رشد گیاهچه های خربزه تحت شرایط تنش شوری شد.

چکیده [English]

The main goal of current experiment was evaluation of the effects Si priming on germination characteristics of melon under salt stress. For this purpose, a factorial experiment based on completely randomized design was conducted with three levels of Si 0 as control, 1 and 2 mM and 3 levels of NaCl (0, 75 and 150 mM) with three replications. Measured traits were germination percentage and rate, mean germination time, radical and plumule length, radical to plumule ratio, radical and plumule fresh weight. The salinity of 150 mM decreased germination percentage and rate, radical and plumule length by 9, 35, 69 and 71X comparing to the control, respectively. Seed priming with Si of 1 mM increased germination rate, radical and plumule length by 20, 33 and 35% comparing to the control, respectively. Seeds treated with Si (1 mM) had the highest germination percentage and rate at 75 mM of NaCl. On the whole, seed priming with Si could improve germination characteristics and seedling growth of melon under salinity stress conditions.
