To test the veracity of these relationships and determine whether any sucrolytic activities were associated with root yield or sucrose accumulation, sucrolytic enzyme activities, fresh and dry mass, and the content of sucrose, glucose, fructose and cell wall materials were measured in roots of three B. vulgaris genotypes with differing yield and sucrose accumulating capacities at five stages in their development. Across all genotypes and developmental stages, sucrose synthase activity was positively associated with root mass, water content, and accumulation of cell wall materials. No meaningful association was observed between alkaline invertase, soluble acid invertase or insol uble acid invertase activities and any of the physical or chemical properties examined. These results suggest that sucrose synthase activity may be a marker for root yield, a factor in root sink strength, and a promoter of cell wall biosynthesis.","PeriodicalId":403165,"journal":{"name":"Journal of Sugarbeet Research","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126137130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Weed control with a single glyphosate application was inadequate for all species except wild mustard. Two sequential applications starting at 2-, 4-, and 6-leaf sugarbeet with a two week interval between applications provided more than 90% weed control. Similar weed control was provided with three applications starting at 2- or 4-leaf sugarbeet with one or two week intervals between applications, respective ly. Residual herbicides followed by one or two applications of' glyphosate starting at 4-leaf sugarbeet provided excel lent weed control. No sugarbeet injury was recorded with glyphosate alone. However, sugarbeet injury with treat ments containing residual herbicides ranged from 0 to 10%. With glyphosate alone, sugarbeet root yield increased as the number and frequency of applications increased. Highest yields were obtained with two or three applications of glyphosate starting at 2- or 4-leaf sugarbeet. Similar yields were obtained with residual herbicides in combina tion with one or two applications of glyphosate starting at 4-leaf sugarbeet. None of the treatments, including the weedy check, affected sucrose content. Sucrose yield dif fered among treatments and corresponded to sugarbeet root yield.

Multiple POST applications are usually required because of continued weed emergence. Frequent POST applications may injure sugarbeet and increase herbicide/application costs; however, too few applications may result in poor weed control and reduced sugarbeet yield and quality. This research determined if growing degree days (GDD) could be used to time postemergence herbicide applications. Common lambsquarters (Chenopodium album L.) and redroot pigweed (Amaranthus retroflexus L.) were controlled in the growth chamber by three microrate herbicide treatments applied on seven day intervals, every 97 or 125 GDD (base temperature of 1.1o C). Two micro-rate applications also provided control of common lambsquarters and redroot pigweed when the first application was at 194 GDD (97 + 97 GDD), followed by the second application at 97 GDD (Table 1). Neither weed species was controlled by three micro-rate applications at 152 GDD, or when the first treatment was delayed until 250 GDD and only two micro-rates were applied. In the field, sugarbeets were planted April 5, April 19, and May 2 in 2001 and April 7, April 17, and May 1 in 2002.

Sugarbeet showed a great capacity to recover from early weed interference, but the recovery did not prevent sucrose yield loss. Sugarbeet sucrose yield was reduced by 99 to 100% by full-season weed interference, and by 5 or 10% if weeds were allowed to interfere with sugarbeet for 2 to 2.5 or 5 to 5.5 weeks after sugarbeet emergence (WAE). Cumulative leaf area duration (LAD cum ) explained differences in sucrose yields between weed interference durations and weed control strategies, and higher LAD cum was the result of higher leaf area expansion rate. Yield loss could be prevented with increased number of hand-weedings if the first two hand-weedings were executed early in the growing season. Three hand-weedings during the sugarbeet canopy establishment phase permitted sucrose yield similar to sugarbeet kept weed-free from 4 WAE until harvest. POST phenmedipham plus sethoxydim gave insufficient weed control and resulted in sucrose yield reductions of 76 to 81%, compared to weed-free sugarbeet. However, a single hand-weeding following POST phenmedipham plus sethoxydim improved sucrose yield by 280 to 350%, compared to sucrose yields obtained with POST herbicides alone. The combination of POST herbicides and one hand-weeding gave a sucrose yield higher than or equal to sucrose yield from sugarbeet hand-weeded three times.

Continuous post-planting hand-weeding for 17 weeks and 15 weeks in 1990, and for 15 weeks and 12.5 weeks in 1991 were required to limit sugarbeet root yield loss to 5% and 10%, respectively. Sucrose content did not vary with increasing weed-free duration. Weed dry weight produced during the growing season and the reduction of cumulative leaf area duration explained most of the reduction in sugarbeet root yields. High cumulative leafarea duration was the result of high leaf area expansion rate. PRE herbicides gave poor weed control and resulted in 100% and 85% sugarbeet yield loss in 1990 and 1991, respectively. The combination of P RE and POST herbicides improved weed control, but yield loss was still significant ; 34% in 1990 and 48% in 1991.
