determination of seed viability constants in medicinal pumpkin (cucurbita pepo l. subsp. pepo. convar. pepo var. styriaca greb), borago (borago officinalis l.) and black cumin (nigella sativa l.)
predicting seed viability would be extremely beneficial to seed producers and the prediction of seed viability depends on understanding the quantitative relationships between seed longevity, seed moisture content and storage temperature. thus, the objective of this investigation was to quantify relationship between temperatures, seed moisture and seed deterioration and determination seed viabil...
متن کاملevaluation of nonlinear regeression models in quantifying germination rate of medicinal pumpkin (cucurbita pepo l. subsp. pepo. convar. pepo var. styriaca greb), borago (borago officinalis l.) and black cumin (nigella sativa l.) to temperature
selection of an appropriate model is important for quantifying response of germination rate to temperature and determination of cardinal temperatures. this study was done to evaluate different nonlinear regression models to describe response of germination rate to temperature in medicinal pumpkin, borago and black cumin. the regression models were dent-like, segmented, beta, curvilinear, quadra...
متن کاملEffect of pruning on growth, development, seed yield and active substances of Pumpkin (Cucurbita pepo convar. pepo var. styriaca)
The objective of this study was to investigate the effect of pruning in different developmental stages on growth, development, seed yield and active substances of medicinal pumpkin (these active substances are uses for remedy the Benign Prostatic Hyperplasia (BPH)). The experiment was performed in a RCB design. Five pruning treatments in different developmental stages (no pruning, after 3-5 nod...

متن کاملارزیابی مدلهای رگرسیون غیرخطی در کمّیسازی جوانهزنی کدو تخمکاغذی (Cucurbita pepo L. subsp. Pepo. Convar.Pepo var. styriaca Greb)، براگو (Borago officinalis L.) و سیاهدانه (Nigella sativa L.) به دما
انتخاب مدل مناسب برای کمّیسازی واکنش سرعت جوانهزنی نسبت به دما در تعیین دقیق دماهای کاردینال بسیار پراهمیت است. پژوهش حاضر به‌منظور ارزیابی مدلهای رگرسیونی غیرخطی برای توصیف سرعت جوانهزنی کدو تخمکاغذی، براگو و سیاهدانه نسبت به دما صورت گرفت. برای توصیف جوانهزنی در مقابل دما از مدلهای دندان‌مانند، دوتکهای، بتا، منحنی، درجه دوم و درجه سوم و برای انتخاب مدل برتر از معیارهای جذر میانگین ...
