تاثير تنش شوري بر پرولين ريشه، قند محلول برگ و رشد آنتوريوم و نقش اسيد ساليسيليك در كنترل آن

The effect of salinity on growth, root proline and soluble carbohydrate in leaf of Anthurium plant and role of salicylic acid in its control

به منظور بررسي تاثير تنش شوري و اسيد ساليسيليك روي پارامترهاي رشدي گياه آنتوريوم آزمايشي انجام شد. شوري در دو سطحds/m 2و0 واسيدساليسيليك درسه سطح ppm و 100 و 200 و 0 آزمايشي بصورت طرح كاملا تصادفي با 6 تيمار كه هر تيمار در 3 تكرار و هر تكرار با 2 گلدان انجام گرفت .اندازه گيريها شامل سطح برگ،طول دمگل،پرولين ريشه و قند محلول برگ بود. بر اساس نتايج بدست آمده شوري تاثيري كاهنده بر سطح برگ، طول دمگل داشته و باعث افزايش پرولين ريشه گرديده. اسيد ساليسيليك باعث افزايش ميزان پرولين ريشه گرديده همچنين تفاوت معني داري در بين گروه هاي تيماري در ميزان قند محلول برگ مشاهده نگرديد.بنابراين بهترين نتيجه در اندازه گيري طول دمگل ،پرولين ريشه در گروه تيماري اسيد ساليسيليك 100ppm همچنين بهترين نتيجه در اندازه گيري سطح برگ درگروه تيماري اسيد ساليسيليك200ppm مشاهده گرديد

In order to, study of the effects of salicylic acid, salinity and their interactions on different aspects of growth in Anthurium andraeanum. Plants were treated with 2 levels of salinity (0 and 2 dsm-1) and/or three levels of salicylic acid (0, 100 and 200 mgl-1) in controlled conditions. The experimental design was completely randomized one. The plants were grouped in six different treatment groups with three replication and 2 pots in each replication. The obtained results indicated that salt stress had reducing effects on different characteristics related to the growth and development of plants such as leaf area, petiole length. The salt stress resulted in the increased root proline. The application of salicylic acid led to the enhanced and modified plant growth and metabolism as it was shown by higher root proline and as well as all the measured parameters like leaf area. The observed differences in, souluble carbohydrate in leaf between treatments were not significant. The best results were found in SA (100 ppm) group. According to our results it could be stated that the application of acid, especially at the level of 100 ppm may has alleviating effects on plants exposed salt conditions
