Abstract:
Two strawberry varieties ‘Benihoppe’ and ‘Akihime’ were used as experimental materials to investigate the plant growth potential between the virus-free and conventional seedlings under different cultivation modes.The results showed that the incidence of leaf diseases in the seedling stage was controlled between 0% and 6% in virus-free seedlings.Under the same cultivation mode,the growth potential of ‘Benihoppe’ and ‘Akihime’ virus-free seedlings were higher than that of conventional seedlings,with increased crown diameter,stolon per plant and inflorescence per plant by 8.40 cm,1.70 cm,1.75,1.77 and 3.89 cm,0.74 cm,1.60,1.10,repectively.At the same time,the incidence of disease in ‘Benihoppe’ virus-free seedlings decreased from 17.33% to 2.66% in conventional seedlings at seedling stage,and 13.33% to 0% at production period.Furthermore,under different cultivation modes,the growth potential of ‘Akihime’ virus-free seedlings under single-layer X-scramble cultivation was higher than that of single-layer single-row cultivation mode by 6.10 cm,2.48 cm,and 2.77 respectively.In summary,the ‘Benihoppe’ and ‘Akihime’ virus-free seedlings grew more vigorously than the conventional seedlings in the seedling stage.The incidence of disease in ‘Benihoppe’ virus-free seedlings was significantly lower than that of conventional seedlings during fruit period.The virus-free seedlings on conventional ridge cultivation mode had higher seedling efficiency than the elevated cultivation mode.
