“…The average mass fraction of water in the fruits of the 'Lovran Marron' (56.7 g per 100 g) is in line with the data published for other sweet chestnut cultivars, which ranges from 40 to 60 % of water (25,31,36,40,(46)(47)(48)50,51,54,69,70). According to Breisch (71) the water content of chestnuts should be between 49 and 60 % for an adequate conservation.…”

Summary'Lovran Marron' is the only known traditional Croatian variety of the sweet chestnut. The objective of this study is to specify qualitative and quantitative morphological characteristics and to analyze the chemical composition of the 'Lovran Marron' fruits as well as to compare them to Marušnjak fruits (trees from the 'Lovran Marron' seed) and fruits from the local natural sweet chestnut population. Seven morphological characteristics were measured: fruit mass, height, width and thickness, scar length and width, and the length of the longest intrusion of the seed coat into the kernel. Eight qualitative characteristics were estimated: embryony, degree of penetration of the seed coat into the kernel, fruit shape, glossiness and colour, kernel colour, hairiness towards the top of the fruit and the existence of longitudinal stripes. 'Lovran Marron' has desirable qualitative and quantitative fruit characteristics. The Marušnjak trees mostly have intermediate morphological traits of fruits in comparison with 'Lovran Marron' and trees from the natural population. 'Lovran Marron' had the smallest mass fractions on average of: K, Mg, Ca, Na, Mn, Cu and Fe. The highest mass fractions on average of these macro-and microelements were characteristic of the trees from the natural population. The highest average content of carbohydrates was recorded in the 'Lovran Marron' and the lowest in the fruits from the natural population. The Marušnjak fruits had intermediate water, protein, ash, carbohydrates, and macro-and microelement content. The content of Cd and Pb was lower in all samples than the maximum allowed amounts in the sweet chestnut fruits.

“…The European chestnut is cultivated for its nuts and wood and can be found on acidic to neutral soils, influenced by an oceanic climate which is characterised by annual mean values of sunlight spanning between 2400 and 2600 h and rainfall ranging between 600 and 1500 mm, mean annual temperature between 9 and 13 • C, 27 • C being the mean of the maximal temperature (Heiniger and Conedera, 1992;Gomes-Laranjo et al, 2008). According to Dinis et al (2011), chestnut regions must have 1900-2200 • D between May and October. The degree-days ( • D) is the sum of the temperature values in degrees Celsius with a base temperature of 6 • C (Cesaraccio et al, 2001;Dinis et al, 2011).…”

Abstract. Due to its economic and nutritional value, the world production of chestnuts is increasing as new stands are being planted in various regions of the world. This work focuses on the relation between weather and annual chestnut production to model the role of weather, to assess the impacts of climate change and to identify appropriate locations for new groves. The exploratory analysis of chestnut production time series and the striking increase of production area have motivated the use for chestnut productivity. A large set of meteorological variables and remote sensing indices were computed and their role on chestnut productivity evaluated with composite and correlation analyses. These results allow for the identification of the variables cluster with a high correlation and impact on chestnut production. Then, different selection methods were used to develop multiple regression models able to explain a considerable fraction of productivity variance: (i) a simulation model (R 2 -value = 87 %) based on the winter and summer temperature and on spring and summer precipitation variables; and, (ii) a model to predict yearly chestnut productivity (R 2 -value of 63 %) with five months in advance, combining meteorological variables and NDVI. Goodness of fit statistic, cross validation and residual analysis demonstrate the model's quality, usefulness and consistency of obtained results.

“…The adaptation of leaf structure, morphologically or histologically, often reflects clearly the effect of environmental stress and therefore is often used as an index evaluating the impacts of environmental conditions on plants (Dinis et al 2011;Souto et al 2009). The significant interactive effect of ecotype and transpiration regulation (P<0.05) indicated that different ecotypes had varying responses to transpirationaltering measures.…”

A b s t r a c t M e c h a n i s m s o f P t e r i s v i t t a t a L . t o hyperaccumulate arsenic (As), especially the efficient translocation of As from rhizoids to fronds, are not clear yet. The present study aims to investigate the role of transpiration in the accumulation of As from the aspects of transpiration regulation and ecotypic difference. Results showed that As accumulation of P. vittata increased proportionally with an increase in the As exposure concentration. Lowering the transpiration rate by 28∼67 % decreased the shoot As concentration by 19∼56 %. Comparison of As distribution under normal treatment and shade treatment indicated that transpiration determines the distribution pattern of As in pinnae. In terms of the ecotypic difference, the P. vittata ecotype from moister and warmer habitat had 40 % higher transpiration and correspondingly 40 % higher shoot As concentration than the ecotype from drier and cooler habitat. Results disclosed that transpiration is the main driver for P. vittata to accumulate and redistribute As in pinnae.
