“…Such resource-based hypothesis is supported on the demand and storage of nutrients and carbohydrates needed to produce a large seed crop, which would deplete them (Isagi et al 1997;Rosecrance et al 1998). However, several studies have not found any evidence of reserves consumption in perennial tissues (Stevenson and Shackel 1998;Miyazaki et al 2002;Yasumura et al 2006).…”

Masting is the intermittent and synchronous production of large crops, but its relation to tree growth remains elusive despite the ecological relevance of mast seeding. The production of huge fruit crops has been linked to the accumulation and consumption of resources as nutrients and carbohydrates, but no conclusive assessment has supported this assumption. To evaluate if masting takes place once trees' canopies reach maximum foliage, changes in canopy cover were measured in Quercus ilex susbp. ballota stands before and after a masting event using the normalized difference vegetation index (NDVI). The results on the whole underline that masting in Q. ilex occurred once maximum levels of NDVI and canopy cover were reached. After the masting event, NDVI dropped, leaf shedding increased and trees produced shorter shoots, narrower tree rings and fewer acorns than before the masting event. These findings support our contention that an increase in canopy cover precedes masting.

“…The ability of perennials to store nutrients to meet a substantial proportion of the early demands of growing leaves and flowers/fruits further complicates the determination of seasonal uptake patterns Titus and Kang, 1982;Tromp, 1983;Millard and Thomson, 1989;Millard and Grelet, 2010). The amount of stored nutrients also varies depending on environment, tree age and species (Weinbaum et al, 1987;Deng et al, 1989;Rosecrance et al, 1998;Weinbaum and Van Kessel, 1998).…”

“…As a result, during the next growth season the apical bud is not supplied with sufficient nutrients to develop a strong shoot. Rosecrance et al (1998) showed that Pistacia vera L. Kerman growing on P. atlantica rootstock are alternate bearing trees, producing nuts every 2 years. They found that this pattern is a result of nutrient storage, influenced by both nutrient accumulation prior to dormancy and by nutrient demand by vegetative and reproductive organs in spring.…”

Impact of a gall-inducing aphid on Pistacia atlantica Desf. trees

The impact of gall-inducing aphids on shoot development was analyzed in 900 shoots from 20 pistachio trees, Pistacia atlantica Desf. (Anacardiaceae): 600 in which the axillary-lateral buds were galled by Slavum wertheimae HRL during the previous growth season, and 300 ungalled shoots. Although P. atlantica is a compensating tree, and the aphids do not attack the apical buds, further development of shoots from the apical buds was stopped in 62% of the galled shoots, while only 8.7% of nongalled shoots stopped their growth. Further development was stopped more often on shoots carrying two or more galls than on shoots supporting only one gall. To assess the hypothesis that bud destruction by the aphids explains this pattern, a field experiment was conducted in 140 shoots, distributed across seven trees. One, two or three axillary buds from five shoots of each tree were removed for each treatment, and five other shoots were marked as controls. Only 14 shoots (10%) of the 140 did not develop. The growth of the other shoots was not very different among the treatments. The colonization of the apical shoots, which developed on previously treated shoots, by three other galling aphid species was monitored. Removing lateral buds considerably reduced the establishment of Geoica sp. galls (70% of them colonized control shoots), but weakly influenced Forda riccobonii (Stefani). It also contributed only 5% of the total variance of the distribution of Smynthurodes betae West. The different results of the survey and the experiment show that the impact of S. wertheimae galls on the future growth of shoots from apical buds is more complex than the simple physical destruction of the axillary buds.
