The Brazilian Soybean Complex
The rise of the Brazilian soybean complex simultaneously tells two important stories. The first story is the classic rise of an industry due to natural resource abundance (the Cerrado) and strategic investments in agricultural technology (low-latitude soybeans). Brazil is now the second leading producer of the fastest growing broad-acre crop in the world, has unparalleled arable land reserves, ...
متن کاملMeiotic behavior and chromosome number of Urochloa adspersa (Trin.) R. D. Webster from the Brazilian Chaco.
This is the first report of meiotic division in Uro-chloa adspersa (Trin.) collected from the Brazilian Chaco. Meiotic analyses were performed on three specimens of U. adspersa named G10, G15, and G16. Inflorescences were collected and fixed in a mixture of ethanol and acetic acid (3:1, v/v) for 24 h and then stored in 70% alcohol. Diakinesis revealed different chromosome numbers and ploidy lev...
متن کاملMeiotic behavior of interspecific hybrids
The meiotic behavior of four interspecific promising hybrids was evaluated by conventional cytological methods. The female genitors were two artificially tetraploidized sexual accessions of B. ruziziensis (R41 and R44, 2n = 4 χ = 36), which were crossed to an agronomically superior natural tetraploid apomictic genotype of B. brizantha (B140 BRA003395). Three of them (HBGC313, HBGC 315, and HBGC...
متن کاملDetermination of Nutritive Value of Soybean Varieties Using in vitro Methods and Gas Production Technique
This study was conducted to determine the nutritive value of soybean varieties using in vitro methods and gas production technique.In vitro gas productions and gas production kinetics of soybean variety were determined at 0, 3, 6, 12, 24, 48, 72 and 96 h incubation times. This study revealed that there were variations among five different soybean varieties in terms of chemical...
متن کاملLife cycle and fecundity of Spodoptera exigua (Lep.: Noctuidae) on five soybean varieties
چرخهی زندگی و باروری کرم برگخوار چغندرقند، Spodoptera exigua (Hübner)، روی پنج رقم سویا در شرایط آزمایشگاهی در دمای 1 ± 25 درجهی سیلسیوس و رطوبت نسبی 5 ± 60٪ و دورهی نوری 16 ساعت روشنایی و 8 ساعت تاریکی مورد بررسی قرار گرفت. طولانیترین دورهی رشد قبل از بلوغ در نرها و مادهها روی رقم L17 (28/0 ± 17/30 و23/0 ± 63/29) مشاهده شد. همچنین، کوتاهترین طول دورهی رشد قبل از بلوغ نر و ماده بهترتی...
