“…Interestingly, addition of 0.3 and 0.4 mL L -1 of PPM reduced contamination, however, mature nodal segments showed oxidative characteristics of PPM phytotoxicity. As mentioned by Carneiro et al [28], high concentrations of PPM can cause the medium to become more acidic due to the formation of HCO3. Therefore, we hypothesize that concentration greater than 0.3 mL L -1 of PPM caused the culture medium where the nodal segments of Persian lime were cultured to be acidic.…”

In vitro propagation is a technique that has been used to produce large-scale, healthy, pathogen-free plants. However, the presence of endophytic microorganisms in explant tissues is one of the limiting factors for the in vitro establishment of any species. In this sense, we studied the effectiveness of PPM® biocide (Plant Preservative Mixture) and Chlorothalonil fungicide to control and/or reduce microbial and fungal contamination in mature nodal segments of different Persian lime clones under in vitro conditions. The results showed that explants cultured in MS medium (Murashige and Skoog 1962) supplemented with 0.2 mL L-1 of PPM biocide + 1.0 mL L-1 of Chlorothalonil were adequate to achieve a higher percentage of disinfection (44%) in mature nodal segments in the Persian lime clones. Furthermore, it was observed that PPM concentrations above 0.3 mL L-1 resulted in greater phytotoxicity in mature nodal segments at 60 days.

“…A semente de B. gaudichaudii, classificada como recalcitrante, apresenta conteúdo de água elevado (62%) e não toleram dessecação, o que dificulta seu armazenamento (MAYRINK et al, 2016). Adicionalmente, as sementes de B. gaudichaudii apresentam elevada germinabilidade em meio de cultura com diferentes condições de pH, com ou sem o tegumento que a reveste (CARNEIRO et al, 2019).…”

O objetivo deste estudo foi avaliar a emergência de plântulas e a morfofisiologia de mudas de mama-cadela (Brosimum gaudichaudii Trécul) produzidas a partir de sementes de diferentes tamanhos. Foram determinadas a porcentagem de emergência de plântulas e as características morfofisiológicas das mudas (altura, diâmetro do colo, índice de robustez, espessura foliar, índice de clorofila, biomassa seca, massa foliar específica - MFE e área foliar total). A emergência iniciou-se após 21 dias da semeadura e atingiu, ao final do experimento, 84% para as sementes pequenas, valor inferior ao das sementes médias e grandes (94 e 90%, respectivamente). Em 60 dias, as mudas apresentavam, em média, 2,53 mm de diâmetro e 12,81 cm de altura. Nos primeiros 30 dias, as mudas formadas a partir de sementes pequenas tinham alturas menores que as demais. O tamanho das sementes não afetou o diâmetro do colo e a espessura das folhas durante o crescimento inicial das mudas, assim como para os parâmetros morfofisiológicos estudados. Ao longo de 120 dias, houve aumento do conteúdo de clorofilas, biomassa seca, área foliar total, exceto para a MFE. O tamanho das sementes afeta a emergência e a altura das mudas de mama-cadela após 30 dias após a emergência. Palavras-chave: Brosimum gaudichaudii; Cerrado; crescimento inicial. Effect of seed size on emergence and mophophysiology of mama-cadela seedlings ABSTRACT: The objective of this study was to evaluate the seedling emergence and morphophysiology of mama-cadela (Brosimum gaudichaudii Trécul) seedlings produced from seeds of different sizes. Seedling emergence percentage and seedling morphophysiological characteristics (height, diameter, slenderness index, leaf thickness, chlorophyll index, dry matter, specific leaf mass - MFE and total leaf area) were determined. The emergence started after 21 days of sowing and reached, at the end of the experiment, 84% for small seeds, lower than the average and large seeds (94 and 90%, respectively). In 60 days, the seedlings had, on average, 2.53 mm in diameter and 12.81 cm in height. In the first 30 days, seedlings formed from small seeds had shorter heights than the others. The seeds size did not affect the diameter and the leaves thickness during the initial growth of the seedlings, as well as for the morphophysiological parameters studied. Over the 120 days, there was an increase in the content of chlorophylls, dry matter, total leaf area, except for MFE. The seeds size affects the emergence and the height at 30 days after mama-cadela seedlings emergence. Keywords: Brosimum gaudichaudii; Brazilian savanna; initial growth.
