Soybeans lab report

The mutant lines utilized included FM6-847 and FM4-2589 and the three USDA lines that served as the reference were LD00-2817,LZD06-7620 and LD07-3395. In the study a number of parameters were examined both pre-harvest as well as post harvest. Key among them; plant heights at the maturity stage just before harvest, the number of pods produced per soybean plant and the seed number emanating from those pods. This was attained by sowing four seeds from each of the seeds under study as well as the reference lines under controlled laboratory conditions of 25 + or -1oC temperature, artificial light and specified pot sizes. The seedlings were later transplanted to an out of lab conditions, precisely the FSU campus field in North Carolina.

, 2004, vegetable soybean contains approximately 50% more Isoflavones compared to the mature soybean seeds. In addition to that, the vegetable soybean is rich in tocopherol (vitamin E) ranging from the 84 to 128 micro grams per gram of the dry seed (Zhang, & Kyei-Boahen, 2007). The soybean also contains vitamin C (ascorbic acid) with minimal quantity of niacin (Gamborg, Miller, & Ojima, 1968). These constituents partly explains why the plant as greatly found key uses in pharmaceutical industries in production of anti-oxidants In its bid to feed the increasingly hungry world, the USA has embarked on several genetically improved soybean with the first ever transgenic soybean being introduced in the mid 1990s as glyphosate-resistant (GR) variety and by 2008 (Zhang, & Kyei-Boahen, 2007), the herbicide tolerant transgenic soybean varieties occupied over 92% of the entire USA soybean acreage (USDA-NASS 2008b) In lieu of the increased performance of transgenic soybean and the escalating demand for food production, this study aims at assessing the yield performance of two mutant varieties of soybean in comparison with the already in use lines (Gamborg, Miller, & Ojima, 1968).

The problem statement being; does the soybean mutant FM6-847 and FM4-2589 yield surpass the yield of the 3 USA lines? The hypothesis; Yes, soybean mutants FM6-847 and FM4-2589 yield surpass the yield of the 3 USA lines. The plants have been treated with a pesticide because of two major insects (Japanese beetle and kudzu bug), watered, and kept in the field until maturity. Trait Measurements and Data Analysis Days to flowering (DF) have been recorded in the field. Plant heights (PH) have been recorded at maturity just before harvest. At maturity, plants have been harvested and brought to the lab to measure pod numbers (PN), seed numbers (SN), 100-seeds weight (100-SW), and total seed weight (TSW). All these measurements have been recorded for all plants in Groups I, II, and III.
