بررسی تاثیر سرکه چوب و کیفیت نور بر رشد و خصوصیات بیوشیمیایی جعفری وحشی (antriscus cerifolium)

گیاه جعفری وحشی (antriscus cerifolium) از گیاهان بسیار ارزشمند دارویی و سبزی محبوب در برخی از مناطق کشور است که به صورت خودرو در بخش هایی از شمال کشور می روید. این مطالعه جهت بررسی اثر سرکه چوب و کیفیت نور بر رشد و فعالیت های بیوشیمیایی گیاه جعفری وحشی در شرایط کنترل شده انجام شد. آزمایش به صورت فاکتوریل در قالب طرح کاملاً تصادفی با 4 تکرار اجرا شد. فاکتور اول غلظت های صفر، 0/5 و 1 درصد سرکه چوب بود که به صورت محلول پاشی هر هفته یکبار صورت پذیرفت و فاکتور دوم کیفیت نور بود که شامل نورهای سفید، قرمز، آبی و قرمز+آبی می شد. گلدان ها با بستر کشت حاوی کوکوپیت+پرلایت (50+50 درصد حجمی) پر شده و با محلول هیدروپونیک کود-آبیاری شدند. نتایج نشان داد که تیمارهای مربوط به کیفیت نور و غلظت های سرکه چوب به طور معنی داری رشد و صفات فیزیولوژیکی گیاه جعفری وحشی را تحت تاثیر قرار دادند. نتایج مقایسه میانگین اثر متقابل نشان داد که استفاده از سرکه چوب در غلظت 0/5 و یک درصد در شرایط نور آبی، به ترتیب وزن تر را از 3 گرم به 8/7 و 5/4 گرم افزایش داد. همچنین در شرایط نور قرمز، وزن تر به ترتیب 50 و 100 درصد در گیاهان تیمارشده با سرکه چوب 0/5 و یک درصد افزایش یافت. علاوه بر این سرکه چوب کاهش کلروفیل ناشی از شرایط نور آبی را به مقدار قابل توجهی افزایش داد. گیاهان پرورش یافته در شرایط نور آبی و قرمز به مراتب وزن تر، فعالیت آنتی اکسیدانی و میزان فنول کمتری نسبت به نور سفید داشتند.

evaluation of influence of wood vinegar and light quality on growth and biochemical traits of chervil plant (antriscus cerifolium)

several species of apiaceae family are well known as a source of essential oils which are used for different purposes including nutrition, medicine, beverages, spices, repellents, staining, cosmetics, fragrances and industrial uses. the genus anthriscus with 12 species growing in europe, eastern north america, africa, new zealand and temperate ragions of asia, belongs to the family apiaceae. the chervil plants are generally well known for their strong and distinctive flavors and in some cases providing important nutrients which can fortify the consumer’s diet to enhance its nutritional value. some of the anthriscus species are used as flavoring agent and spice for culinary purposes. wood vinegar is a liquid condensed from carbonized flue gas in producing biochar from agricultural and forestry waste under high temperature and hypoxia. it is a green and environmentally friendly biomass material with sterilization and insect control effects. the conducted analysis demonstrated that wood vinegar contains 10–20 % and more than 200 different types of organic compounds. better understanding of relations between light quality and plants growth is highly important to produce crops with desired qualitative and quantitative characteristics. there are several studies conducted on the effect of light parameters on crops characteristics, and results have shown that changing the quality and quantity of light can significantly affect physiological, biochemical and productivity of agricultural plants. studies demonstrated that photosynthesis rate, antioxidant compounds, growth parameters, nutritional value and medicinal characteristics are affected by quality and duration of light radiation. so, in the current study the effect of light quality and wood vinegar application on some of most important characteristics of chervil plant (antriscus cerifolium) was investigated.   2.materials and methods: in order to investigate the effect of light quality and wood vinegar application on some of most important characteristics of chervil plant, a factorial experiment was performed based on completely randomized design with 4 replications at department of horticultural sciences, university of mohaghegh ardabili, ardabil, iran. the chervil seeds were sown on growing media (perlite + coco-peat) in plastic pots. seeds were kept under dark condition for 3 days. after germination, pots were transferred to growing chamber with light intensity of 3000 lux, and 16/8 h day/night photoperiod. pots were fertigated with hydroponic solution. plants were subjected to different light quality conditions (white, red, blue, blue + red). air temperature ranged between 18 to 20 ° seedlings were sprayed with the concentrations of 0, 0.5 and 1 % of wood vinegar at a 7 days intervals. morphological and physiochemical traits including survival rate, fresh weight, chlorophyll content, phenolic compounds, flavonoid content and antioxidant activity were evaluated after 4 weeks. analysis of variance and mean comparisons (based on lsd test at 5 % probability level) were performed by sas software.3.results and discussion: results showed that physiological and biochemical traits of chervil plant were significantly affected by light quality and wood vinegar application.
