“…Resprouts that originated after perturbations show thereafter high growth and photosynthesis rates as reported by our group (Fleck et al 1998). There is little difference between the physiology of tree resprouts that originated in the forest after fire and those that originated after excision (Fleck et al 1996). The availability of underground reserves and water from the extensive root system to the small resprouting shoots enable regrowth and survival after damage.…”

The physiological characteristics of holm oak (Quercus ilex L.) resprouts originated from plants grown under current CO2 concentration (350 μl l−1) (A‐resprouts) were compared with those of resprouts originated from plants grown under elevated CO2 (750 μl l−1) (E‐resprouts). At their respective CO2 growth concentration, no differences were observed in photosynthesis and chlorophyll fluorescence parameters between the two kinds of resprout. E‐resprouts appeared earlier and showed lower stomatal conductance, higher water‐use efficiency and increased growth (higher leaf, stem and root biomass and increased height). Analyses of leaf chemical composition showed the effect of elevated [CO2] on structural polysaccharide (higher cellulose content), but no accumulation of total non‐structural carbohydrate on area or dry weight basis was seen. Four months after appearance, downregulation of photosynthesis and electron transport components was observed in E‐resprouts: lower photosynthetic capacity, photosystem II quantum efficiency, photochemical quenching of fluorescence and relative electron transport rate. Reduction in ribulose‐1,5‐bisphosphate carboxylase/oxygenase (RuBisCo) activity, deduced from the maximum carboxylation velocity of RuBisCo, accounts for the observed acclimation. Increased susceptibility of photosynthetic apparatus to increasing irradiance was detected in E‐resprouts.

“…Similar results were reported in other plants. Fleck et al [16] reported that girdling treatment increased the contents of total polyphenols, condensed tannins, free gallic, esterified gallic, protocatechuic and syringic acids in shoot foliage of Quercus ilex. Gholami [17] also reported that the girdling treatment at the early berry growth of berry significantly affected the contents of anthocyanins, total phenolics, glycosides, weight and total soluble solids.…”

Oolong tea is one of the most popular beverages due to the presence of significant amount of catechins. Experiments were conducted to investigate the effect of girdling treatment on levels of catechins in fresh tea leaf related to quality of the 'Huang Zhi Xiang' Oolong tea (Camellia sinensis). The variations in the levels of catechins in fresh tea leaf and the quality score (QS) of the 'Huang Zhi Xiang' Oolong tea were examined. The study demonstrated that girdling treatment increased significantly the levels of (-)-epicatechin, (-)-epigallocatechin, (-)-epigallocatechin gallate, (-)-epicatechin gallate, total catechins, simple catechin, and catechin gallate present in fresh leaf of tea trees. Furthermore, the girdling treatment improved significantly the quality of the 'Huang Zhi Xiang' Oolong tea. Thus, it was suggested that application of girdling treatment could be an effective agronomic practice to increase the quality of 'Huang Zhi Xiang' Oolong tea.

“…Similar results were found in other plants. Fleck et al [15] observed that the shoot foliage of fire girdled Quercus ilex exhibited higher values of total polyphenols, condensed tannins, free gallic, esterified gallic, protocatechuic and syringic acids than those found in the shoot foliage of nongirdled tea trees. In addition, according to Chen et al [14], the contents of TC, EGCG and CG in fresh tea leaf were significantly correlated with the quality of Oolong tea.…”

The contents of starch and catechins in the fresh leaf of 'Huang Zhi Xiang' Oolong tea trees girdled at the bottom, middle (on the big branches) and top (on the small branches) were determined. The study demonstrated that the starch contents from girdled trees were significantly higher (p<0.05) than that from non-girdled ones. Furthermore, the contents of (-)-epicatechin (EC), (-)-epigallocatechin (EGC), total catechins (TC) and simple catechins (SC) from girdled trees were significantly higher (p<0.05) than those from non-girdled ones. Especially, the contents of (-)-epigallocatechin gallate (EGCG), (-)-epicatechin gallate (ECG) and catechin gallate (CG) from girdled at the middle were also significantly higher (p<0.05) than those from the non-girdled. The starch contents were negatively correlated with the contents of (-)-gallocatechin (GC), EC, SC, TC and EGC, while positively correlated with the contents of EGCG and CG in fresh shoots.
