چکیده

سوسن چلچراغ از گونه‌های خودروی جنس سوسن است که در بخش‌های شمالی ایران می‌روید. این گونه به‌عنوان یک گل جدید، دارای ارزش زینتی و پتانسیل اقتصادی بالایی، جهت عرضه در بازار جهانی می‌باشد. استفاده از روش‌های کشت بافت می‌تواند امکان تولید گیاه را در سطح وسیع از تعداد کم نمونه میسر ‌سازد. کاربرد فراصوت به‌عنوان یک محرک فیزیکی به همراه تنظیم‌کننده‌‌های رشد به‌عنوان محرک شیمیایی می‌تواند در تکثیر این گیاه مؤثر باشد. بدین منظور ریزنمونه‌های فلس این گیاه پس از قرارگیری در حمام فراصوت، در محیط کشت MS حاوی غلظت‌های مختلف NAA و BA به تنهایی و یا به‌صورت ترکیب با یکدیگر کشت گردیدند. این آزمایش در قالب فاکتوریل بر پایه‌ی طرح کاملاً تصادفی و با چهار تکرار صورت گرفت. نتایج نشان داد که در ترکیب‌های تیماری صفر، 01/0، 1/0 میلی‌گرم در لیتر NAA به‌علاوه 5 ثانیه فراصوت، 1/0 میلی‌گرم در لیتر NAA به‌علاوه 10 ثانیه و 1 میلی‌گرم در لیتر NAA به‌علاوه صفر، 5، 20 و 30 ثانیه فراصوت‌دهی بیشترین تعداد پیازچه را نسبت به شاهد داشتند. محیط کشت MS حاوی تیمار صفر میلی‌گرم در لیتر BA به‌علاوه 5 ثانیه فراصوت دارای بیشترین تعداد پیازچه‌های باززایی شده بود. با این حال ترکیب تیماری 1/0 میلی‌گرم در لیتر BA به‌علاوه 5 ثانیه فراصوت نیز ضمن داشتن تعداد پیازچه‌ی زیاد، پیازچه‌های درشت‌تری نیز داشت. بنابراین به نظر می‌رسد تیمار فراصوت در ترکیب با هورمون در محیط کشت بافت در تحریک پیازچه‌زایی در ریزنمونه فلس مؤثر است.

چکیده [English]

Abstract
Background and Objectives
Lilium ledebourii is one of the wild species of Lilium genus, growing in northern Iran. This species has high potential for export. Plant tissue culture techniques are widely used in plant propagation, and using these methods can effectively provide micro-propagation of this plant in the large scale. High percentage of regeneration is necessary for plant protection, used in the breeding programs.
Materials and Methods
The experiment was factorial based on completely randomized design with four replications and was carried out in tissue culture Lab of Mohaghegh Ardabili University in 2015. For this purpose, segments of explant that were treated with ultrasound were cultured on MS medium supplemented with different concentrations of NAA and BA alone and/or in combination with each other. This experiment conducted Concentrations of NAA at four level Zero, 0.01, 0.1 and 1 mgl-1 and Concentrations of BAP at four levels Zero, 0.01, 0.1 and 1 mgl-1 and Ultrasound at four levels zero, 5, 10, 20 and 30 seconds. In order to remove possible contamination from the mediums, all media were autoclaved for 30 minutes at 121 °C. At the end of the experiment, the number of bulblet produced, root length, fresh weight of bulblet and etc were recorded. The cultures were kept at 20°C or 25°C under 16 h photoperiod or in darkness.
Results
The results showed the highest number of bulblets produced in 0, 0.01, 0.1 mg L-1 NAA and 5secend ultrasound, 0.1 mg L-1 NAA and 0, 5, 20 and 30 second ultrasound compared with control. The highest frequency of bulblet regeneration was produced in MS medium supplemented with 0, 0.01, 0.1 mg L-1 NAA and 5 second ultrasound. On the other hand, 0.1 mg L-1 NAA and 5 second ultrasound increased number and weight of bulblets. Different concentrations of NAA had also significant effects.
Discussion
On the other hand, ultrasound increased the number and weight of bulblets. Mechanical stress and micro streaming by acoustic cavitation might be considered as the most possible cause of the various physiological effects of ultrasound on cells. Low-energy ultrasound can modify cellular metabolisms or facilitate the uptake of nutrient, and make them easily through the cellular walls and membranes. Finally, it seems that ultrasound in combination with growth regulators have the potential to produce the highest average number of bulblets in the scale explant, using plant growth regulators in combination with an abiotic stress in in vitro
