摘要

2020年,阿拉巴马州、佐治亚州和佛罗里达州生产的棉花出现了数量异常的种皮碎片(SCF)报告,导致该地区的价格扣除超过2300万美元,仅佐治亚州的贷款价值就减少了1800万美元。为了了解是什么导致了SCF呼叫的历史数量,对来自佐治亚州的各种试验样本进行了SCF问题评估。试验在格鲁吉亚的24个地点进行,包括12个品种。在美国乔治亚州蒂夫顿的UGA Microgin采集286份棉籽样品,收集2份纤维样品,1份用于High Volume Instrument, 1份用于Advanced fiber Information System (AFIS)分析,1份用于游离脂肪酸(FFA)分析。送到田纳西州孟菲斯市班级办公室的样本都没有接到无关紧要的电话;然而,不同地点和品种的AFIS种皮nep (SCN)计数、垃圾和FFA存在差异。种类的影响不如地点的影响,这表明地点之间的环境差异是造成差异的原因。从第一次开铃到收获的降雨越多,SCN计数增加。此外,随着平均日太阳辐射的增加,SCN计数减少。因此,确定明显和长期的风化可能是导致东南部SCF问题爆发的原因。未来的研究应继续评价环境对外来物发生的影响,以及确定棉绒中外来物发生的客观方法。

Impact of Environmental Conditions and Variety on Seed Coat Fragment Issues in Georgia in 2020
In 2020, there were an abnormal number of seed coat fragment (SCF) reports from cotton produced in Alabama, Georgia, and Florida resulting in price deductions of more than $23 million in the region and $18 million in Georgia alone based on loan value. To understand what led to the historic number of SCF calls, variety trial samples from Georgia were evaluated for SCF issues. Trials were conducted across 24 locations in Georgia and included 12 varieties. A total of 286 seedcotton samples were ginned at the UGA Microgin in Tifton, GA, and two fiber samples were collected, one for High Volume Instrument and one for Advanced Fiber Information System (AFIS) analysis, and a seed sample was collected for free fatty acid (FFA) analysis. None of the samples sent to the Memphis, TN classing office received an extraneous matter call; however, there were differences in AFIS seed coat nep (SCN) counts, trash, and FFA when evaluated by site and variety. Variety was not as impactful as location, indicating that environmental differences between sites were responsible for the differences. As more rainfall occurred from first open boll to harvest, SCN count increased. Additionally, as average daily solar radiation increased, SCN count decreased. Therefore, it was determined that significant and prolonged weathering is what likely led to the outbreak of SCF issues in the Southeast. Future research should continue to evaluate environmental impacts on the occurrence of extraneous matter as well as an objective method to determine extraneous matter occurrences in cotton lint.
