CRESCIMENTO DE MUDAS DE AÇOITA-CAVALO (Luehea divaricata Mart.) SOB INFLUÊNCIA DE DIFERENTES SUBSTRATOS E RECIPIENTES, EM VIVEIRO

Abstract

Luehea divaricata is a native species widely distributed in Brazil, widely used as a medicinal plant and reforestation programs. In order to provide quality seedlings for these projects, this research aims to study the development of Luehea divaricata in different substrates and recipients. Arrays tree seeds were collected in the city of Silveira Martins, and the experiment was conducted in a greenhouse at the Federal University of Santa Maria. They used three volumes of substrates and three different tube sizes (50, 110 and 180 cm³) and three commercial substrate compositions, peat-based (Carolina Soil®) plus carbonized rice husk (CAC)-(100 Peat %, 80% peat + 20% and CAC 60% peat + 40% CAC). For data analysis was used completely randomized design (CRD) in a factorial scheme with four replicates per treatment. Data analysis was performed using 5% Tukey test. The experimental results demonstrate that larger containers (180 cm³) would be the most suitable for production Luehea divaricata, as well as the combination of peat 100% as a base substrate. The species can be transplanted into the field around 150 days after sowing.

Influence of fluorescent Pseudomonas on the growth of Mimosa scabrella seedlings

“…For seedling production, techniques that aim at shortterm production and high-quality plants to successfully establish themselves at the field are extremely important. They result in high percentage of survival and replanting reduction (Felker et al, 2015). It is common to perform the inoculation of beneficial microorganisms in plants in order to improve their development, as well as to increase tolerance to diseases and enable the establishment under stress conditions such as salinity and drought (Niu et al 2018;Ferreira et al, 2019).…”

Desenvolvimento inicial de combinações de enxertos de laranjeiras doces sobre porta-enxertos de citrandarin e tangerineira

“…De acordo com Felker et al (2015), altura da parte aérea fornece uma excelente estimativa da predição do crescimento inicial, sendo tecnicamente aceita como uma boa medida do potencial de desempenho das mudas, além de não acarretar destruição das plantas. Dessa forma as copas 'Pera D6' e Natal apresentaram bom desenvolvimento inicial comparado a Pera rio.…”
