“…Since the AGR allows the average growth rate (g day -1 ) to be measured throughout the evaluation period, it should be noted that only the Capdeboscq cultivar showed a continuous increasing trend in the rate throughout the growth of the plant, attributing this difference to the vigour shown by the cultivar, which, at 80 DAT, resulted in an AGR approximately twice as great as the other cultivars under evaluation. suggesting that at the start of development the plants were composed of young leaves of high photosynthetic capacity, which promoted the rapid accumulation of biomass, a fact that again characterises the cultivar as of high initial vigour, as previously described by Schmitz et al (2014) and Souza et al (2018).…”

“…From the analysis of variance, it could be seen that there was no significant interaction between the factors rootstock cultivar and growth period (DAT) for any of the growth variables under evaluation (Table 1), the effect of each factor was therefore evaluated separately. In relation to growth period, there was an increase in height and stem diameter, with the highest values reached at 80 DAT (Figure 2A Considering the period after sowing, the rootstock in the present study was ready for grafting at 104 DAS, a shorter period than that obtained by Schmitz et al (2014) and Fischer et al (2016), suggesting that the reduced time taken for the rootstock to reach the grafting stage may have been the result of fertilisation by the commercial substrate, a factor that distinguished the present study from the above-mentioned studies, and which probably promoted the growth in CD.…”

“…Considering each cultivar separately, 'Capdeboscq' and 'Flordaguard' showed greater SDM production (1.79 and 1.75 g plant -1 , respectively), followed by 'Okinawa Roxo' (1.42 g plant -1 ) ( Figure 3B), with the same behaviour being seen for the RDM variable. According to the literature, 'Capdeboscq' is characterised by high initial vigour, which has helped promote and sustain its use in rootstock production for obtaining stone-fruit seedlings in Brazil (Schmitz et al, 2014;Souza et al, 2018).…”

“…According to the need for improvements in the production chain of peach rootstock (Reis et al, 2010;Schmitz et al, 2014;Fischer et al, 2016) the aim of this study was to analyze the initial growth and accompany nutrient accumulation in three peach rootstocks until the grafting stage.…”

Analysing growth and nutrient accumulation is generally employed for guiding the fertilisation practices in the seedling-production chain. In the production of peach rootstock, such evaluations can provide information to aid can to aid in discrimination available genotypes, especially regarding the efficient use and conversion of fertiliser into dry matter, which can reduce the time required to obtain plants suitable for grafting. The aim of this study, was to investigate the differences in growth and nutrient accumulation in three peach-rootstock cultivars. A completely randomised experimental design was used, in a 3 x 4 factorial scheme, including three peach rootstocks ('Flordaguard', 'Capdeboscq' and 'Okinawa Roxo') and four periods of growth evaluation (20, 40, 60 and 80 days after transplanting - DAT), giving a total of 12 treatments, with four replications, one for each plant. The Flordaguard and Capdeboscq cultivars showed greater height and stem diameter as well as a greater accumulation of total dry matter at 80 DAT, and both followed the distribution: leaves (67%) > roots (33%), while total dry-matter production in 'Okinawa Roxo' was less, following the order: leaves (71%) > roots (29%). The rootstock under evaluation showed variations in growth, confirmed by the physiological indices, except for the leaf area and specific leaf area. In general, macronutrient accumulation in the shoots and roots of the cultivars during each growth period was different, suggesting intrinsic differences in each of the genetic materials regarding nutrient demand for maintaining the metabolic processes which are vital to plant growth.

“…The identification of rootstocks suited to different soil and climatic conditions of cultivation and its initial performance in different conditions of nursery, are of great interest in the production of seedlings sector (SCHMITZ et al, 2014). In order to install orchards with a high productive potential, it is essential to use seedlings free of pests and diseases and presenting recognized genetic potential.…”

CHARACTERIZATION OF LEAVES AND FRUITS OF MANGO (Mangifera indica L.) CV. IMBU

-Although mango is one of the tropical fruits of greater interest in world trade, literature concerning their rootstocks (characteristics and utilization) is scarce. This study aimed to characterize mango plants from cv. Imbú, widely used as rootstock in the Zona da Mata region, Minas Gerais (MG), Brazil. Though fruits of this cultivar do not present desirable commercial characteristics, this study allowed us to characterize part of plant morphology and fill a gap in the literature, providing subsidies for future investigations. For such, 'Imbú' plants (≈ 4-years old) from the collection of the Universidade Federal de Viçosa, located in Viçosa -MG were evaluated. The descriptors were: (i) leaf blade division;(ii) leaf composition; (iii) petiole length in relation to leaf blade; (iv) phyllotaxis, (v) leaf position in relation to the branch insertion; (vi) leaf shape; (vii) leaf apex and base angles; (viii) leaf margin category; (ix) venation; (x) leaf length and thickness; (xi) leaf length/thickness ratio; (xii) leaf texture; (xiii) leaf fragrance; (xix) leaf color. The leaves were depicted as lanceolate, with entire margins and sharp angles at the base and apex of the leaf blade. The intensity of the green color of the leaf blade was considered intermediate and the abaxial surface staining showed less intense than that observed in the upper side. The fruits were processed and separated into peel, pulp and seeds in order to evaluate the flesh color, fresh weight and percentage of seeds, peel and pulp. Was determined the soluble solids content, starch concentration, the peel and the pulp color, the cerosity, the percentage evaluation of peel, pulp and seed and the pulp firmness. The average number of germinated seedlings per seed was estimated for 230 sown seeds. Index terms: Rootstock, Mangifera indica, morphology CARACTERIZAÇÃO DE FOLHAS E FRUTOS DA MANGUEIRA(Mangifera indica L.) CV. IMBÚ RESUMO -Apesar de a manga ser uma das frutas tropicais de maior interesse no comércio mundial, a literatura sobre os seus porta-enxertos (características e utilização) é escassa. Este estudo teve como objetivo caracterizar as mangueiras da cv. Imbu, amplamente utilizada como porta-enxerto na região da Zona da Mata de Minas Gerais (MG), Brasil. E, embora frutos dessa cultivar não apresentem características comerciais desejáveis, este estudo permitiu caracterizar parte da morfologia da planta e preencher uma lacuna na literatura, fornecendo subsídios para futuras investigações. Para tal, folhas completamente expandidas da porção mediana de ramos expostos à luz solar e frutos plenamente desenvolvidos foram coletados de plantas da cv. 'Imbu' (≈ 4 anos de idade) da coleção da Universidade Federal de Viçosa, localizada no município de Viçosa -MG. Os descritores foram: (i) divisão lâmina de folha; (ii) a composição da folha; (iii) comprimento do pecíolo em relação à lâmina de folha; (iv) filotaxia, (v) a posição das folhas em relação à inserção do ramo; (vi) a forma de folha; (vii) ângulos do vértice da folha e de base; (viii...
