Effects of Oxytetracycline on Growth and Phenotypic Plasticity of Pepper Plants
In order to study the effect of veterinary oxytetracycline stress on the growth of pepper plants,a randomized block design was used to study,the effects of persistent stress with different concentrations of oxytetracycline(0 mg/L,50 mg/L,100 mg/L,150 mg/L,200 mg/L)on the morphological characteristics,component biomass and biomass distribution of pepper plants and analyze,their phenotypic plasticity and survival strategies.The results showed that with the increasing of oxytetracycline concentration,the number of flowers,branches and fruits,root biomass,stem biomass,leaf biomass and total biomass all showed a trend from rise to decline,and plant height and main root length showed a gradual upward trend,but the number of vanes and root ratio showed a downward trend.The number of flowers and fruits,root biomass,leaf biomass and fruit biomass displayed obvious plasticity to oxytetracycline stress.The fruit,leaf and stem biomasses were all lower than the root biomass of pepper plants,and biomass allocation of root appeared to be the highest.It is the stronger phenotypic plasticity of pepper that enabled its good performance in survival,growth and breed.
