“…in winter and spring and the lowest at the end of winter and summer (Figure 1). The increase in the content of Na during winter coincided with the driest period and was probably related to the loss of weight of senescent leaves (data not shown) and/or decrease in leaching, as previously reported in the literature (PALMA et al, 2000). During the period of yellowing, there is a steady outward movement of mobile elements such as Na from the leaves.…”

“…Cultivar/rootstock interaction were not oserved. Previous work on plum in HDP system also reported a high variability among cultivars regarding this parameter (SOSNA, 2002;MELAND, 2005;PEPPELMAN et al, 2007). There were significant difference in yield per tree and unit area among cultivars ( Table 7).…”

“…Montagnini (1990) stated that seasonal changes in the levels of nutrients, including also Na, in fruit trees largely depend on the bioelement cycle, tree development stage and climate and soil factors. These variations in nutrient content were greater in leaves than in shoots and fruits (CANNEL; KIMEU, 1971;PALMA et al, 2000;SOARES et al, 2008). The present study suggests that Na displayed the greatest seasonality in shoots, possibly due to its being the most mobile element (HELMISAARI, 1992).…”

Seasonal changes and content of sodium in main organs of European plum trees (Prunus domestica L.), fruit size and yield as affected by rootstocks on acidic soilMudanças sazonais no teor de sódio dos órgãos, tamanho do fruto e produção da ameixeira européia (Prunus domestica L.) em função de porta-enxertos em solo ácido AbstractIn the present study, the seasonal changes of Na content of shoots, flower buds and flowers, and fruit weight and yield of two European plum cultivars ('Cacanska Lepotica' and 'Cacanska Najbolja') budded on Myrobalan (Prunus cerasifera Ehrh.) and Stanley rootstocks were analyzed after 6-8 years of planting on acidic sandy-loam soil. The Na content of the shoots and flower buds of each rootstock/ cultivar combination varied during season, and the highest content in above organs was observed in May and August, respectively. The effect of rootstocks on the examined parameters was variable due to the strong rootstock/cultivar/year interaction observed. The shoots and flower buds of cultivars budded on Stanley and Myrobalan rootstocks gave the highest and lowest Na content, respectively, whereas the highest Na content in flowers registered in 'Cacanska Lepotica' on Myrobalan. The content of Na in the plum organs suggests the following trends: 1-year old shoots > 2-year-old shoots > flower buds > flowers. There were no statistically significant correlations among plum organs with respect to Na content. The Principal Component Analysis showed that Stanley rootstock had a higher Na accumulation and distribution capacity than Myrobalan rootstock in plum trees. Finally, content of Na in the main organs of plum trees and acidic soil have not a negative effect on fruit weight and yield of plum cultivars, since these properties were respectable. Key words: Acidic soil, fruit weight and yield, plum trees, shoots, sodium accumulation ResumoNeste estudo, foram analisadas as mudanças sazonais do teor de Na nos ramos, botões florais e flores, bem como no peso dos frutos e na produtividade de duas cultivares de ameixeiras européias ('Cacanska lepotica' e 'Cacanska najbolja') enxertadas sobre os porta-enxertos Myrobalan (Prunus cerasifera Ehch.) e Stanley, aos 6-8 anos após o plantio em solo ácido areno-argiloso. O conteúdo de Na nos ramos e nos botões florais para cada combinação de copa/porta-enxerto teve a variação durante a temporada e o maior teor foi constatado em maio e agôsto, respectivamente. A influência do porta-enxerto sobre os parâmetros estudados foi variável devido à forte interação copa/porta-enxerto/ano. Os ramos e botãos florais das plantas enxertadas sobre os porta-enxerto Stanley e Myrobalan, tiveram o maior e o menor teor de Na, respectivamente; enquanto o maior teor de Na nas flores foi registrado na 'Cacanska lepotica' sobre o porta-enxerto Myrobalan. O conteúdo de Na nos órgãos de ameixa teve a seguinte evolução: ramos de 1 ano > ramos de 2 anos > botões florai > flores. Não houve correlação significativa entre os órgãos da ameixeira em termos de teor de Na. A Análise de Componentes P...

“…In addition, rates of nutrient return to the forest soil are controlled not only by the amount of litter production but also by the nutrient concentrations in litter components (Yang et al 2006;Mlambo and Nyathi 2007). Since at the research sites, there are not conclusive studies related to global warming and long-term tendencies, in this study, the significant seasonal differences in biomass production might have been related, to some extent, to concurrent seasonal extreme environmental conditions such as droughts and frosts, which are typical in the northeastern region of Mexico (González-Rodríguez et al 2000, González-Rodríguez et al 2004 and or changes in phenological events such as leaf abscission and shedding, shoot initiation, flowering, and fruiting (Palma et al 2000). Previous findings in Northeastern Mexico (González-Rodríguez et al 2007) have revealed that during wet months (August and September) when rainfall was heavy, branches and fruits were the main litter constituents, whereas in the dry and winter months, there was a greater contribution of leaves due to drought and freezing temperatures.…”

“…The production and litter decomposition are important mechanisms in the nutrient cycling in vegetation areas (Steubing et al, 2001). Nevertheless, Palma et al (2000) argue that seasonal differences in production and nutritional quality of litter could be related to extreme climatic fluctuations and/or phenological changes such as abscission and bud initiation, flowering and fruiting.…”

The aim of the study was to determine monthly (2007) the content and deposition of Cu, Fe, Mn and Zn in leaf fallen litterfall samples collected in four sites, northeastern Mexico. Site 1 was located at 1600 m of altitude in a pine forest, mixed with deciduous trees; site 2 was at 550 m in the ecotone of a Quercus spp. forest and submontane scrub; sites 3 and 4 (at 350 m and at 300 m, respectively) were located in the Tamaulipan Thornscrub vegetation. Leaf fallen litterfall samples at each site (2,500 m 2 ) were obtained from ten canisters of 1.0 2 m that were randomly situated at each site. The Cu annual deposition (g ha -1 yr -1 ) was significantly different among sites being higher in site 4 (23.2) and lower in site 1 (4.1). Fe deposition was also significantly higher in site 4 (522.2) and lower in site 1 (120.0). Mn was higher in site 2 (479.4) and lower in site 1 (64.6). Zn was significantly higher in site 1 (62.8) and lower in site 1 (24.3). Micronutrient annual order deposition was as follows: Fe>Mn>Zn>Cu. Differences in deposition may be attributable to environmental conditions and plant species composition at each studied plant community.
