| 中文摘要: |
| 以马铃薯不同基因型品种脱毒基础苗为试验材料，采用两因素随机区组设计,研究不同基因型品种、不同抗生素浓度对马铃薯脱毒基础苗苗鲜重、根鲜重、苗干重、根干重、叶片数、节数、株高、茎粗、根长和根条数等农艺性状影响，培养14 d时，测定各性状指标。结果表明：3个不同成熟期基因型品种对测定的10个农艺性状指标影响显著(P<0.05)；4种抗生素浓度（0、20、40、60 mg·L-1）除了茎粗
，对其它9个农艺性状指标影响显著(P<0.05)，适宜的抗生素浓度范围为0 mg·L-1和20 mg·L-1；3个不同成熟期基因型品种、4种不同抗生素浓度处理对马铃薯
单株苗鲜重、根鲜重、苗干重、根干重、节数、株高、茎粗、根条数影响有显著性交互作用
(P<0.05)，叶片数、根长不受基因型品种和抗生素浓度交互作用影响；早熟基因型品种
大西洋、中熟基因型品种克新1和晚熟基因型品种青薯168适宜的抗生素浓度为0、20 mg·L
-1，各农艺性状表现好。为预防污染发生，降低生产成本，建议继代3-5代时,加入抗
生素20 mg·L-1。 |
| 英文摘要: |
| The different varieties of virus free potato plan
tlets were selected as the meterials, and using the method of randomized block d
esign of two factor to study the effects of genotypes and different antibiotic
concentrations on the fresh weight of shoot and root, the dry weight of shoot an
d root, leaf number, node number, plant height, stem diameter, root length and r
oot number of individuals after 14 d culture. Our results showed that genotypes
had significant effects on the ten agronomic traits (P<0.05). Four kinds of
antibiotic concentrations（0、20、40、60 mg·L-1）had notable interacti
on effects on other agronomic characters eccept stem diameter (P<0.05), the
suitable antibiotic concentrations were 0 mg·L-1 and 20 mg·L-1. Ex
cept for leaf number and root length properties index, the genotypes and antibio
tic concentrationshad notable interactions on other agronomic characters eccept
(P<0.05). The suitable antibiotic concentrations for the early maturing va
rietie “Atlantic”, medium maturing varietie “Kexin 1” and late maturing va
rietie “Qingshu 168” were 0 mg·L-1 and 20 mg·L-1, to prevent the
pollution and production reduction, we suggested to add 20 mg·L-1 antibi
otic if subcultured for 3-5 generations. |
