中文摘要:
      采用处理频率和处理时间双因素试验,设置6种超声波处理(A:25 kHz、1 min;B:25 kHz、3 min;C:25 kHz、5 min;D:33 kHz、1 min;E:33 kHz、3 min;F:33 kHz、5 min),以未处理为对照(CK),研究超声波处理对果蔗产量、品质及生理特性的影响。结果表明:与对照相比,超声波处理对果蔗萌芽率、分蘖率、生长速、株高、单茎质量及有效茎数均具有促进作用,果蔗蔗茎产量增产幅度为10.28%~55.60%,甘蔗糖分增减幅度为-0.39%~0.79%(绝对值);可提高果蔗苗期、分蘖期、伸长初期叶片过氧化氢酶、过氧化物酶、超氧化物歧化酶等抗氧化酶活性,降低叶片质膜丙二醛含量,增强果蔗抗逆性。筛选出较优超声波处理为33 kHz、5 min(该处理下蔗茎产量增产55.60%,甘蔗糖分提高0.31个百分点)。
英文摘要:
      To study the effect of ultrasonic treatment on the yield,quality and physiological characteristics of chewing cane,and to provide scientific basis for the application of ultrasonic treatment in the production of chewing cane.Six treatments (A:25 kHz,1 min; B:25 kHz,3 min; C:25 kHz,5 min; D:33 kHz,1 min; E:33 kHz,3 min; F:33 kHz,5 min) were set up based on the two-factor experiment of different treatment frequencies and different treatment time.In addition,the untreated buds were used as control (CK).The results showed that,compared with the control,the ultrasonic treatment had a promoting effect on the budding rate,tillering rate,growth rate,plant height,single stem weight and effective stem number of hectare,and the cane yield increased by 10.28%-55.60%,and sucrose content increased by -0.39%-0.79% (absolute value).The activity of antioxidant enzymes,such as catalase,peroxidase and superoxide dismutase in leaves at the seedling stage,tillering stage and early jointing stage,could be improved,and the content of malondialdehyde in leaf plasma membrane could be reduced,and the resistance to chewing cane could be enhanced.Comprehensive analysis showed that the best treatment was 33 kHz and 5 min (cane yield increased by 55.60% and sucrose content increased by 0.31%).The research results have reference value for the application of ultrasonic treatment in chewing cane production.
