effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Using L-M BP Algorithm Forecase the 305 Days Production of First-Breed Dairy
Aiming at the shortage of conventional BP algorithm, a BP neural net works improved by L-M algorithm is put forward. On the basis of the network, a Prediction model for 305 day’s milk productions was set up. Traditional methods finish these data must spend at least 305 days, But this model can forecast first-breed dairy’s 305 days milk production ahead of 215 days. The validity of the improved ...
متن کاملGenetic and phenotypic parameters of lactations longer than 305 days (extended lactations).
Test-day milk yield and somatic cell count data over extended lactation (lactation to 540-600 days) were analysed considering part lactations as different traits and fitting random regression (RR) models. Data on Australian Jersey and Holstein Friesian (HF) were used to demonstrate the shape of the lactation curve and data on HF were used for genetic study. Test-day data from about 100 000 cows...
متن کاملGenetic analysis of grain yield, days to flowering and maturity in oilseed rape (Brassica napus L.) using diallel crosses
Twenty one F2 progenies derived from a 7×7 diallel crosses along with parents were evaluated for grain yield, flowering and maturity time. Due to significant genotypic effects for all traits, genetic analyses were performed on F2 progenies including analyses of combining ability and genetic components. The Analysis of variance revealed that both additive and non-additive genetic effects were in...
متن کاملCme 305 :
At lunchtime it’s crucial for people to get to the food trucks as quickly as possible. The building is represented by a graph G = (V,E) where each room, landing, or other location is represented by a vertex and each corridor or stairway is represented by an edge. Each corridor has associated capacity c, meaning that at most c people can pass through the corridor at once. Traversing a corridor f...
