“…In the present study, avocado trees planted in clay soil (C) had more biomass partitioned to the woody portion of the trees, and less partitioned to the "annual" organs such as shoots and roots. Bonomelli and Artacho [45] reported that in young cherry trees (age 1-3 years) fine and main roots represented approximately 30% of the biomass of trees in unrestricted soils, similar to the observed proportion found in this study for avocado trees in CL, SL and S soils. In the clay soil, avocado roots reached only 20% of the total biomass, probably due to the mechanical impedance and/or lack of aeration caused by low soil macroporosity [34].…”

A two-year study was conducted to determine how soil texture affects calcium (Ca) absorption and partitioning in potted ‘Hass’ avocado trees. Trees were planted in 200 L pots in one of four soil types: clay (C), clay loam (CL), sandy loam (SL) or sand (S). Prior to planting, Ca content in each soil was in the normal range of availability, although the Ca concentration was highest in C soil. After two years of tree development, dry weights of shoots and roots were significantly higher in the SL and S soils than in C soil. Trees in the C soil had higher wood dry weight than trees in SL or S soils. The Ca contents (absolute quantities, not concentrations) in the roots, shoots and whole tree were significantly lower in the C soil than in the SL or S soils. The K/Ca ratio of trees in the C soil (K/Ca = 1.5) was significantly higher than that in the other soil types. Stem water potential was significantly lower for trees in the C soil compared to the other soils. These results indicate that Ca absorption and partitioning in young avocado trees varies with soil texture, probably associated with soil effects on root growth and/or plant water status.

“…Chili pepper had approximately 30 % leaf biomass, while sweet cherry trees had a leaf biomass below 10 %, which may be associated with a trade-off between forming woody tissues or leaves in the woody species (Cornelissen et al, 1996). Similar root biomass partitioning values have been reported for cherry (Bonomelli and Artacho, 2013) and sweet orange trees (Mattos Jr. et al, 2003). When analyzing the rate of 45 Ca transport and accumulation, both species showed certain similarities.…”

Calcium (Ca) is often supplied to crop species to prevent the occurrence of Ca-related disorders. Mechanisms of Ca absorption and transport are not fully understood and the effectiveness of root and/or foliar Ca fertilization may be variable. To characterize the rate of Ca absorption and transport, trials were developed with chili pepper and sweet cherry plants, using 45 CaCl 2 as a tracer. The Ca treatments supplied were: (1) No 45 Ca (control); (2) 45 Ca soil application; (3) 45 Ca supply to basal leaves, and (4) 45 Ca application to apical leaves. After two months, plants were harvested for biomass and Ca content determination. The recovery of 45 Ca in different plant parts was measured with a liquid scintillation counter and leaf traits were observed by scanning electronic microscopy. In general, the highest 45 Ca concentrations were recovered in treated organs, while root applications led to highest 45 Ca translocation rates, which varied between chili pepper and cherry plants. For chili pepper, 45 Ca applied to the soil was detected mainly in roots (44 %) followed by leaves (36.6 %) stems (17.4 %) and fruits (2 %). In sweet cherry trees, soil-applied 45 Ca was principally recovered in roots (45.3 %), shoots (28.5 %), leaves (14.3 %) and trunks (11.9 %). The results provide evidence of increased absorption of root-applied Ca, as well as different degrees of Ca mobility between species. Foliar application led to major Ca increases in treated leaves, with Ca transported to other plant organs after apical leaf Ca supply chiefly in cherry trees.

“…'Bing' on Gisela ® 6 rootstock (Prunus cerasus × Prunus canescens) located in Chile's central region (34°08′S and 70°43′W). The orchard was planted in August 2006 as part of a wider N optimization experiment (see Bonomelli and Artacho 2013), with trees spaced 2.5 m apart within rows and 4.5 m apart between rows (889 trees ha −1 ). The 'Black Tartarian' cultivar was used as a pollinizer in a tree proportion of 11%.…”

Factors regulating fine-root growth are poorly understood, particularly in fruit tree species. In this context, the effects of N addition on the temporal and spatial distribution of fine-root growth and on the fine-root turnover were assessed in irrigated sweet cherry trees. The influence of other exogenous and endogenous factors was also examined. The rhizotron technique was used to measure the length-based fine-root growth in trees fertilized at two N rates (0 and 60 kg ha(-1)), and the above-ground growth, leaf net assimilation, and air and soil variables were simultaneously monitored. N fertilization exerted a basal effect throughout the season, changing the magnitude, temporal patterns and spatial distribution of fine-root production and mortality. Specifically, N addition enhanced the total fine-root production by increasing rates and extending the production period. On average, N-fertilized trees had a length-based production that was 110-180% higher than in control trees, depending on growing season. Mortality was proportional to production, but turnover rates were inconsistently affected. Root production and mortality was homogeneously distributed in the soil profile of N-fertilized trees while control trees had 70-80% of the total fine-root production and mortality concentrated below 50 cm depth. Root mortality rates were associated with soil temperature and water content. In contrast, root production rates were primarily under endogenous control, specifically through source-sink relationships, which in turn were affected by N supply through changes in leaf photosynthetic level. Therefore, exogenous and endogenous factors interacted to control the fine-root dynamics of irrigated sweet cherry trees.
