四杂系列高粱在吉林省的高粱生产中占主导地位,其中具有代表性的吉林省首例用自选抗蚜恢复系140R配制的抗蚜高秆杂交种四杂4号早已被人们所熟知,并成为了玉米制种田中高秆障碍隔离之首选.而具有多抗性的中秆高粱杂交种四杂25号更是以其产量高、抗性好、高抗蚜虫、适应地区广等特点,广泛分布于吉林省的中部、西部、南部地区,占吉林省适应区高粱面积的50%以上,同时也扩展到黑龙江、内蒙古、辽宁等部分地区,并以其高价格卖点引起社会轰动.除此,四杂系列其它高粱也正处于逐年扩展的推广当中,并获得了可观的经济效益和良好的社会效益. 相似文献

Reduced lignin concentration in brown mid-rib mutants in both maize and sorghum have resulted in improved dry matter digestibility, increased milk yield and higher energy in lactating cows. However, the mutations were not widely deployed due to concern that reduced lignin concentration might increase vulnerability to lodging and stalk rot incidence. The objective of this study was to determine the effects of the mutations on stalk strength and stalk rot resistance in both sorghum and maize. Six brown midrib (bmr) sorghum, four brown midrib (bm) maize, and their normal isolines were evaluated for stalk strength and stalk rot disease reaction at two locations in four replications. Three randomly selected plants in each plot were inoculated with Macrophomina phaseolina at 14 d after flowering by using the toothpick inoculation technique. On 28 d after inoculation, the plants were rated for disease severity by measuring the length of necrotic lesions in the stalks. Stalk strength was determined from another three random plants in each plot by using a rind penetrometer. The mutations had no effect on stalk rot disease severity in either sorghum or maize though stalks strength was markedly affected by the mutations in both species. While maize bm entries broke easily in response to mild mechanical stress, bmr sorghums did not exhibit sign of stalk collapse in all backgrounds. The result suggests that the bmr genes in both maize and sorghum can be deployed without incurring losses to stalk rot disease. 相似文献

The chopped sweet sorghum stalk was thin-layer-dried for long-term storage and ethanol production. The drying kinetics and the effects of drying temperature on the qualities of sweet sorghum stalk were investigated in this work. The results showed that the drying process could be simulated well by Wang and Singh's model. The diffusivity constant (D0) and active energy (Ea) were estimated as 4.4 × 10−5 m2/s and 21.4 kJ/(mol K) for drying the chopped fresh stalk. According to the sugar composition, browning degree, and fermentability of the dried stalk obtained at various temperatures, the approximate drying temperature could be suggested as 50-60 °C for application. In this range, the moisture of the chopped fresh stalk could drop below the safe moisture for storage in 7-5.5 h with 12.1-9.7% total sugar loss during the drying process. 相似文献

吉林省玉米茎腐病病原菌组成、分布和优势种研究 总被引:2,自引:0,他引:2
1991~1995年在吉林省六个地区主要栽培品种上采集1016个病株标样.经分离、鉴定及致病性试验重分离验证,明确在吉林省玉米茎腐病病原菌由(Fusarium sp.)和(Pythium sp.)组成.其中(Fusarium graminearum)是吉林省的优势种.其次为(Fusarium moniliforme)和(Pythium sp.)。病原菌的组成、分布存在区域间和年度间的差异。在吉林地区是以(Pythium sp.)为优势种。提出玉米茎腐病的研究工作应立足于本生态区内进行,以求达到控制和减少该病害发生危害的目的. 相似文献
