“…The sharp increase in LAI at 60 DAP could be due to the increased production of leaves and the rapid rate of leaf expansion. LAI decreased at the beginning of senescence as reported by Villa et al (2017) and Bisognin and Dellai (2015). Silva and Pinto (2005) also noticed that LAI of 2.5 to 3 was optimal for maximum light interception in potato plants.…”

“…Dry matter production depends on the size of the leaf canopy, the rate at which the leaf functions (effi-ciency) and the time the canopy lasts (duration) (Belhu, 2003). There is a significant difference between potato varieties/cultivars with respect to dry matter production (Hammes and De Jager, 1990;Bisognin and Dellai, 2015). The commonly used growth analysis parameters are leaf area index (LAI), relative growth rate (RGR), net assimilation rate (NAR), and crop growth rate (CGR) (Gardner at al., 1985).…”

“…O Brasil e outros países com condições agroclimáticas adversas à produção de batata semente a campo, poderiam se tornar auto-suficientes na produção de batata semente se tanto plantas com origem propagativa de micropropagação quanto os minitubérculos fossem adotados em seus programas nacionais de produção de batata semente. O cultivo em sistema semi hidropônico usando areia como substrato vêm sendo empregado para produção de batata pré-básica pois possibilita a redução da contaminação da semente por patógenos de solo, além de permitindo maior controle da aplicação de nutrientes e a colheita dos tubérculos de forma única ou escalonada (SAUSEN et al, 2020;DELLAI, 2015;CORRÊA et al, 2008;MÜLLER et al, 2007).…”
