Manejo da densidade de plantas durante a produção de mudas em viveiro

Abstract: O objetivo do estudo foi otimizar a densidade de plantas em canteiro durante a produção de mudas em tubetes. Para isso, o experimento foi conduzido por meio da produção de mudas seminais de um híbrido de Eucalyptus urophylla x Eucalyptus grandis, composto por sete tratamentos e quatro repetições de 70 plantas por parcela. Cada tratamento consistiu na redução da densidade de mudas no canteiro pela metade em diferentes momentos durante o processo de produção. As mudas foram produzidas em tubetes de polipropileno… Show more

“…Anyway, a lower PH/SD ratio contributes to increase SQI, which leads us to infer that seedlings with a lower PH/ SD tend to be of better quality than those with a higher PH/SD. As well as for forest species, whose PH/SD can vary depending on several factors, such as substrate, fertilization, seedling age (Faria et al, 2019), for passion fruit this index certainly varies depending on factors of seedling production and the region. Therefore, because it is easy to measure and has the advantage of including two non-destructive variables, determining a PH/SD standard for passion fruit is necessary.…”

“…The heights of the seedlings produced in the treatments exceeded the values reported in the literature(Silva et al, 2020;Cordeiro et al, 2019). According toJunghans et al (2017), yellow passion fruit seedlings are suitable for planting at 15-30 cm height, which would accredit the Laf + Com growing media with a potential use in the production of passion fruit seedlings without fertil-ization.ization, and seedling age(Faria et al, 2019). Higher mean values for NL were obtained for the Bcf + Ascb, Bcf + Laf, Bcf + Lcf, Bcf + Al, Bcf + Com, Ascb + Com, Laf + Lcf, Laf + Al, Laf + Com, Lcf + Com, Al + Com, Bcf, Al and Com (Figure…”

“…Desta forma, é fundamental que se estabeleça novos povoamentos para que a restauração florestal ocorra, aliado a isso, adotar técnicas silviculturais que possam suprir essa demanda sem acarretar gastos onerosos. Neste contexto, o êxito de um povoamento florestal passa por critérios como formação de mudas de qualidades, e posteriormente, o desempenho à campo (Faria et al, 2019).…”
