“…(Table 4) In this respect, Satisha et al, (2010) observed that, significant differences were observed in shoot length and other vegetative parameters among different rootstocks of Thompson seedless grapes during all years of the study. However, there was no effect of rootstock on shoot growth rate of Hass avocado trees (Mickelbart et al, 2012).…”

The present study was carried out through 2013 and 2014 seasons in a private orchard at Cairo/Alex. desert road on 21 years old Picholine, Frantoio, Mission, Manzanillo and Koroneiki olive rootstocks which were re-juveniled and top grafted at 2008 season by Kalamata and Dolce olive cultivars. Trees were planted at 6 × 6 meters planting distances, and grown in Sandy soil under drip irrigation system. The aim of the present study was carried out to investigate the effect of different rootstocks (Picholine, Frantoio, Mission, Manzanillo and Koroneiki) on the productivity of the main two black table cultivars in Egypt (Kalamata and Dolce). The results noticed that, vegetative growth parameters varied according to the influence of the studied rootstocks on Kalamata and Dolce cvs., whereas Kalamta scion grafted on Picholine rootstock presented the highest values of tree height, trunk perimeter, trunk cross section area and shoot length, while the first of the three previous parameters were recorded their best values with Dolce trees grafted on Frantoio rootstock. Also, Picholine rootstock with Dolce trees gave the earliest date of (beginning, full blooming and ending of flowering) and the highest numbers of inflorescences/meter, total flowers/inflorescence, fruit set/meter, while Picholine and Mission rootstocks gave the highest yield of Dolce tree Furthermore, Kalamta trees achieved the highest fruit set with Picholine rootstock and the best yield with (Picholine, Frantoio and Mission rootstocks) and gave the heaviest fruit and flesh weight with Mission rootstock. On the other hand, Koroneiki and Manzanillo rootstocks were influenced negatively on the two studied cultivars (Kalamata and Dolce) and gave the lowest values in most of studied characteristics. Under the same conditions of the present study, it could be concluded that, Picholine rootstock followed by Mission then Farantoio revealed the highest productivity of Kalamata trees. However, Dolce Cultivar has achieved the maximum productivity with Picholine and Mission rootstocks.

“…One or two peaks in the annual root growth of apple trees have been reported to occur at different times, depending on the scion/rootstock combination, but always asynchronous with the peaks of shoot growth (Ma et al, 2013). Similarly, avocado root growth was slower during shoot growth flushes (Mickelbart et al, 2012).…”

The objectives of the paper were to study the pattern of root growth (measured by minirhizotrons) in relation to trunk, fruit and shoot growth and the effects of crop load on tree growth and yield in peach trees. Two crop load (commercial and low) treatments were applied in a mature early-maturing peach tree orchard growing in Mediterranean conditions. Root growth dynamics were measured using minirhizotrons during one growing season. Shoot, trunk and fruit growth were also measured. At harvest, all fruits were weighed, counted and sized. Roots grew throughout the year but at lower rates during the active fruit growth phase. Root growth was asynchronous with shoot growth, while root and trunk growth rates were highest after harvest, when the canopy was big enough to allocate the photo-assimilates to organs that would ensure the following season's yield. Shoot and fruit growth was greater in the low crop load treatment and was accompanied by a non-significant increase in root growth. High level of fruit thinning decreased the current yield but the fruits were more marketable because of their greater size.Additional keywords: fruit growth; minirhizotrons; phenology; Prunus persica L.

“…In these cases, internal signaling such as photoassimilate transport may control root growth (Sloan & Jacobs, ), such that roots cannot grow when shoots are consuming the majority of photoassimilate. Supporting this, several studies have observed patterns of alternating root and shoot growth (Drew & Ledig, ; Reich et al ., ; Cardon et al ., ; Mickelbart et al ., ).…”

SummaryGlobally, root production accounts for 33-67% of terrestrial net primary productivity and influences decomposition via root production and turnover, carbon (C) allocation to mycorrhizal fungi and root exudation. As recognized above ground, the timing of phenological events affects terrestrial C balance, yet there is no parallel understanding for below-ground phenology. In this paper we examine the phenology of root production and its relationship to temperature, soil moisture, and above-ground phenology. Synthesizing 87 observations of whole-plant phenology from 40 studies, we found that, on average, root growth occurs 25 AE 8 d after shoot growth but that the offset between the peak in root and shoot growth varies > 200 d across biomes (boreal, temperate, Mediterranean, and subtropical). Root and shoot growth are positively correlated with median monthly temperature and mean monthly precipitation in boreal, temperate, and subtropical biomes. However, a temperature hysteresis in these biomes leads to the hypothesis that internal controls over C allocation to roots are an equally, if not more, important driver of phenology. The specific mechanisms are as yet unclear but they are likely mediated by some combination of photoassimilate supply, hormonal signaling, and growth form.
