چکیده مقاله :
In many parts of Iran high light intensities during summer can induce stress in cut flower production under open field and greenhouse conditions. Despite roses prefer sunny places for optimum growth, but in practice some levels of rough shading is applied in greenhouse production to improve the quality of cut flowers. So, it is useful to find the light intensities under which different rose cultivars produce optimum yield with acceptable market quality. In present study, different light intensities were applied for two rose cultivars of ‘Red One’ and ‘Gulmira’, by shading levels of 1200 (without shading as control), 640, 520 and 240 µmol m-2 s-1, using green plastic nets. The result showed that leaf protein concentration, peroxidase activity, petal anthocyanin concentration and carbohydrate levels were significantly different among shade treatments, as the highest protein concentration was observed in 640 µmolm-2 s-1. The highest concentration of anthocyanin of petals was observed in ʻRed Oneʼ under 520 µmolm-2 s-1. Furthermore, in ʻGulmiraʼ the highest amount of anthocynin was in 520 µmol m-2 s-1, but this was not statistically significant compared to other shading treatments. The highest amount of leaf carbohydrate was in 520 µmol m-2 s-1. The results indicate that shading up to a light intensity of 520 µmol m-2 s-1 is beneficial for quality improvement of these rose cultivars when light intensity is high.
در بسیاری مناطق ایران شدت نور در طول تابستان می­تواند منجر به تنش نوری در گیاهان تحت شرایط گلخانه و هوای آزاد شود. علی­رغم اینکه رزها جهت رشد بهینه مکان­های آفتابی را می­پسندند، اما در عمل به صورت تجربی مقداری سایه­دهی در تولید رزهای گلخانه­ای در بین کشاورزان منطقه جهت بهبود کیفیت گل تولیدی اعمال می­شود. یافتن شدت نوری که ارقام مختلف رز عملکرد و کیفیت مطلوب را تولید کنند بسیار ضروری است. در مطالعه حاضر شدت­ نورهای مختلف برای دو رقم رز "Red One" و “Gulmira” بوسیله سطوح مختلف سایه­دهی 1200، 640، 520 و 240 میکرومول بر مترمربع بر ثانیه بوسیله توری­های پلاستیکی سبز رنگ بکار رفت. نتایج نشان داد که غلظت پروتئین برگ، فعالیت پراکسیداز، مقادیر کربوهیدراتها و غلظت آنتوسیانین گلبرگ به طور معنی­داری تحت تأثیر سطوح سایه­دهی قرار گرفتند. بالاترین غلظت پروتئین در تیمار شدت نور 640 میکرومول بر مترمربع بر ثانیه بدست آمد. بالاترین غلظت آنتوسیانین گلبرگها در رقم “Red One” و تحت شدت نور 520 میکرومول بر مترمربع بر ثانیه بدست آمد. در رقم “Gulmira” نیز بیشترین مقدار آنتوسیانین در همین شدت نور بدست آمد ولی تفاوت آماری با دیگر تیمارهای سایه­دهی نداشتند. بیشترین غلظت کربوهیدراتهای برگ در شدت نور 520 میکرومول بر مترمربع بر ثانیه بدست آمد. نتایج بطور کلی بیانگر آن است که وقتی شدت نور بالاست، سایه­دهی تا یک شدت نور حدود 520 میکرومول بر مترمربع بر ثانیه می­تواند منجر به بهبود کیفی گل رز شود.
