“…Os maiores teores foram observados nas hastes sem armazenamento e colhidas com 120 dias de idade (8,1%) (Figuras 3a, b). Esse fato parece estar relacionado ao consumo de açúcares devido a sua utilização no proces- so respiratório das hastes (Kozlowski, 1992), que foi maior naquelas com idade de 100 dias, por terem menores reservas acumuladas do que as hastes colhidas aos 120 e 140 dias.…”

“…Os maiores teores ocorreram nas hastes não armazenadas com idade de 140 dias (56%), e menor para aquelas com idade de 100 dias armazenadas por 120 dias (12%) (Figuras 4c, d). Esses resultados podem estar relacionados com a utilização de carboidratos de reserva pelas hastes, com a finalidade de sintetizar açúcares solúveis para a proteção dos tecidos contra as baixas temperaturas da câmara fria (Kozlowski, 1992;Kramer & Kozlowski, 1979;Stieckman & Boe, 1978;Wong et al, 2003) e com a pouca idade da haste (100 dias), insuficiente para acumular amido, se comparado aos demais tratamentos.…”

Effect of different storage periods on bud grafting viability of citrus bubsticks at different stages of developmentCitrus buds require special storage conditions in order to keep their viability for future grafting. The objective of this work was to evaluate the effect of different storage periods and different budstick ages on bud viability of two sweet orange cultivars. The experiments were arranged as a 2 x 3 x 3 factorial and set out in a randomized complete block design using two sweet orange cultivars ('Baianinha' and 'Pêra Rio'), three different storage periods (0, 60 and 120 days) and three different ages (100, 120 and 140 days) with four replications, with each plot consisting of six budsticks. Bud viability of orange cv. 'Baianinha' was reduced to 83.4% when stored for 120 days, however the storage period did not affect cv. 'Pêra Rio'. Budstick age had no influence on bud viability of cv. 'Baianinha', however, there was an increase in bud viability of cv. 'Pêra Rio' from 91% (100 days old) to 100% (140 days old). Positive and significant correlation (r = 0,78; p <0,01) between total soluble solids and grafted shoot growth, as well as dry matter and starch levels of budsticks (r = 0,94; p <0,05) occurred for cv. 'Baianinha'.. Viabilidade de hastes porta-borbulhas de citros em diferentes estádios de desenvolvimento e períodos de armazenamento Key words:Borbulhas de citros requerem condições especiais de armazenamento para que, após determinado período de conservação ainda mantenham sua viabilidade para a enxertia. Este trabalho objetivou avaliar o efeito da idade das hastes porta-borbulhas de dois cultivares de laranja doce e do período de armazenamento sobre a viabilidade das borbulhas para enxertia. Utilizou-se o delineamento em blocos casualizados, em esquema fatorial 2 x 2 x 3, avaliando-se dois cultivares de laranjeira ('Baianinha' e 'Pêra Rio'), três períodos de armazenamento (0, 60 e 120 dias), hastes de três idades (100, 120 e 140 dias) e quatro repetições, sendo a parcela constituída por seis hastes porta-borbulhas. A viabilidade para enxertia das borbulhas da laranjeira 'Baianinha' foi reduzida para 83,4%, quando armazenadas por 120 dias, fato não observado para 'Pêra Rio'. A idade das hastes não influenciou a viabilidade das borbulhas da laranjeira 'Baianinha', enquanto para a 'Pêra Rio' ocorreu elevação de 91% de viabilidade quando retiradas de hastes com 100 dias de idade e para 100% de viabilidade para hastes de 140 dias. Para a laranjeira 'Baianinha' houve correlação positiva e significativa (r = 0,78; p < 0,01) entre os teores de açúcares solúveis totais das hastes e o crescimento das brotações dos enxertos e entre a massa seca e os teores de amido das hastes (r = 0,94; p < 0,05).

“…The light interception by the tree canopy is determined by tree spacing, canopy density and height (Jackson, 1980). Due to variations in light intensity in different parts of the tree crown, the photosynthesis within the crown is expected to decrease rapidly with increasing depth of foliage (Kozlowski, 1992). Thus, the light availability and photosynthetic rate of leaves positioned at different levels in the tree canopy under higher density planting system is very important.…”

“…In particular, in a recent work where A. brasilense Sp245 was examined to test its influence on rooting processes of some rootstocks that do not easily root through conventional techniques, the treatment improved propagation and the quality of the root system [8]. However, the effects are not always uniform, suggesting an influence of genetic diversity [14], nutritional and hormonal status of the cuttings [15,16]. Moreover, the interaction of these factors with environmental conditions may be responsible for the response variability to Azospirillum treatments [8].…”

Information about the influence of the plant growth promoting rhizobacteria Azospirillum brasilense Sp245 on the development of grapevine plants could be promoted to enhance sustainable agricultural practices for globally important fruit crops such as grapes. Thus, this study was initiated to evaluate the potential influence of A. brasilense Sp245 on two separate experimental trials, A) potted young grape plants: cv. 'Colorino' grafted onto two rootstocks 420A and 157/11 which received a fixed volume of inoculum at different times of vegetative cycle; B) hardwood cuttings from rootstock mother-plants of 420A and 775P inoculated during the phase of hydration, before bench-grafting in a specialized nursery. Overall, our results revealed that A. brasilense Sp245 has considerable potential to enhance the root apparatus and vegetative development in grapevines. Potted plants inoculated with A. brasilense Sp245 showed an improved development. Repeated supply was revealed to be more effective, inducing a greater accumulation of dry mass. Interesting findings were obtained in nursery experiments resulting from a considerable enhancement of the final quality of roots. The stimulating effect of A. brasilense Sp245 on vegetative development of rootstocks and vines may indeed improve sustainability in viticulture, through the promotion of healthy growth and a reduced dependence on fertilizers and other chemicals
