انگور و محصولات بدست آمده از آن به خاطر مصرف در تغذیه انسان، اهمیت فراوانی در دنیا دارند. با این وجود، این محصولات ممکن است گاهی اوقات به دلیل قیمت و کیفیت پایین در تغذیه نشخوارکنندگان استفاده شود. اهداف این پژوهش تعیین ارزش غذایی انگور رقم بی‌دانه سفید در سه مرحله غوره (خوشه کامل)، رسیده (خوشه کامل)، و کشمش برای نشخوارکنندگان به صورت اندازه‌گیری ترکیب شیمیایی و ویژگی‌های تخمیر‌پذیری به روش تولید گاز در محیط آزمایشگاهی، بررسی ساختار مولکولی با استفاده از روش FTIR (اسپکتروسکوپی مادون قرمز با تبدیل فوریه) و آلودگی‌های عناصر سنگین و سموم قارچی بود. در مقایسه با انگور رسیده و کشمش، غوره نسب نیتروژن به کربوهیدارت، فنول و تانن کل بیشتری داشت (05/0>P) و بیشترین ناحیه پیک مربوط به ترکیبات فنولی و کربوهیدارت‌های ساختاری در بررسی FTIR مربوط به میوه غوره بود (05/0>P). کشمش تولید گاز تجمعی بیشتری در 24 ساعت از انکوباسیون داشت (05/0>P). مقادیر آفلاتوکسین B1، B2، G1 و G2 و آکراتوکسین A در میوه غوره و رسیده ناچیز بود در صورتیکه مقادیر کمی در کشمش مشاهده شد (05/0>P). غلظت سرب در میوه غوره و کشمش کمتر از میوه رسیده بود (05/0>P). در نتیجه، ترکیبات فنولی و تانن‌ها، غلظت سموم قارچی و عناصر سنگین در میوه غوره و رسیده و کشمش انگور بی‌دانه سفید کمتر از سطوح سمی برای تغذیه در نشخوارکنندگان بود و الگو و قابلیت دسترسی مواد مغذی این محصولات، آنها را به عنوان ماده خوراکی مناسب در جیره نشخوارکنندگان ممکن می‌سازد.

This study was carried out to adaptability evaluation of the 50 grapevine varieties introduced from Russia from 2008 to 2013 in the Qazvin and Urmia provinces. The experimental design was randomized complete block design with three replications. Three superior grapevine clones of white Bidaneh were as control in both areas. The Corden bilateral training system was used in 2×3.5 m space planning and two vines in each experimental unit in the both areas. Recorded traits were: yield per plant, length and width of berry, total soluble solids of juice (TSS), juice pH, juice titratable acid (TA) and time of harvest. Combined analysis of variance and adaptability analysis was performed on the base of GGE Biplot principal components analysis of the environment scaling method. Statistical analysis was done by GenStat ver.12 computer software. The effects of the environments, varieties and environments × varieties were significant in the combined analysis of variance. The adaptability of Zenbil 13-366 and Ljana was higher than other varieties on the base of yield components in Qazvin. Ruski Ramphi had higher adaptability than other varieties in Urmia region. Yoski biser, Bobili magaracha and Ramphi Izdangareh had the most inappropriate situation on the base of yield components in two areas.

Abstract Yield components and genetic contribution in final yield have important roles in crop plants breeding programs. For this purpose, 20 varieties of grapevines with Russia origin were evaluated in Urmia and Takestan research station (under full irrigation and drought stress). This research was performed in randomized complete block design with three replications and three plants in each plot in 2012. Number of cluster per plant, number of berry per cluster, berry weight and yield per plants were recorded. Compound and logarithmic analysis of variance, genotype and environmental interaction effects were estimated by multiplicative three environmental and genotypic elements. Results of path analysis indicated that the number of cluster per plant had the highest genetic contribution in final yield and the most sensitivity and variation in different environments. Direct effect of the number of cluster per plant in final yield (0.61) was higher than direct effect of the number of berry per cluster (0.48) and berry weight (0.30). Path coefficient of number of cluster per plant value was higher than path coefficient berry per cluster and berry weight.Therefore, the sequence of manifestation of yield components was number of cluster per plant, number of berry per cluster and berry weight, respectively. Environmental components of interaction effects indicated that absolute value of number of cluster per plant was higher than number of berry per cluster and berry weight. This indicated higher sensitivity of number of cluster per plant in different environments.
