“…was improved after trunk girdling at the pit-hardening stage (Agusti et al, 1998;Day and DeJong, 1990). In an extensive trial in Río Negro and Neuqu en Upper Valley, Argentina, girdling pear (Pyrus communis) trees increased yield compared with the ungirdled control in two seasons (Raffo et al, 2011). Vine girdling in table grapes (Vitis vinifera) increased berry and cluster weight (Fallahi et al, 2017;Reynolds and de Savigny, 2004) but decreased soluble solids concentration and titratable acidity (Reynolds and de Savigny, 2004).…”

The increasing scarcity of land and water for agriculture mandates an efficient use of these natural resources. Establishment of high-density orchards with the use of a size-controlling rootstock, in combination with a suitable canopy architecture, is an efficient method for fruit production. However, less attention has been paid to the use of size-controlling practices such as trunk girdling in these modern orchard systems. The impacts of two rootstocks, two tree architectures, and three levels of bark cambium cuts (girdling or scoring) on growth, yield, fruit quality attributes at harvest, and leaf nitrogen (N) in 'Aztec Fuji' apple (Malus domestica Borkh.) were studied in 2015 and 2016. Trees on Nic 29 had larger canopies, higher yields, and larger fruit, but lower fruit color, sunburn, and firmness than those on Bud 9. Trees with a tall spindle (TS) architecture had higher yield in 2016, higher fruit soluble solids and firmness in 2015, higher fruit russet in 2016, but shorter terminal growth in both 2015 and 2016 and lower leaf N in 2015 than did those with a central leader (CL) training system. Trees receiving a bark girdling in 2015 (BG15) or score girdling in 2015 and 2016 (SG1516) had significantly higher yield than trees on nongirdled trees (NOGD) in 2016. Bark girdling or score girdling in 2015 (BG15 or SG15) increased fruit weight (size), color, and firmness at harvest in the same year, although differences for score girdling were not always significant. However, BG15 or SG15 did not have a ''carryover'' effect and did not affect fruit size, color, or firmness at harvest in 2016. When bark scoring was repeated in 2016 (SG1516), fruit size was increased in 2016. On the basis of the results of this 2-year study, it appears that bark girdling in one year is sufficient to increase fruit size of the current year and the yield in the following year. If larger fruit size is the critical objective of fruit production, annual score girdling needs to be practiced. However, a further long-term study is needed to monitor the carryover effects of cambium girdling and scoring on tree performance and fruit quality attributes in the subsequent years.

“…These results are in harmony with those found by Khattab et al (2003) who indicated second to the fourth year from planting, the trees yielded more fruits than those regulated by pruning only. In addition, Raffo et al (2011) on pear trees, Poniedzialek et al (2001) on apple trees and Baljit Kumar and Harminder Singh (2008) on peach trees proved that all the used girdling treatments significantly increased fruit number, fruit weight and fruit yield. Moreover, Girish Sharma and Ananda (2004) and Moneruzzaman et al (2011) on apple trees observed that, the application of GA 3 at 50 mg/L increased fruit number, weight and yield, however, spraying with 20 mg/L GA 3 increased the number of buds and fruit setting and reduced bud dropping before anthesis.…”

The present investigation was carried out in private orchard at south El-Tahreer region, EL Behera governorate, on 5-years-old "Le Conte" pear trees (Pyrus communis L.× Pyrus pyrifolia N.) budded on (Pyrus betulaefolia) rootstock, during two growing seasons (2009 and 2010). The aim of this research was to study the effect of shoot bending, shoot girdling and GA 3 application on the vegetative growth, yield and fruit quality.The results indicated that gibberellic acid (GA 3 ) application and shoot bending three years old treatments induced significant increment in leaf area, spurs number, fruit set %, number of fruits per tree, total yield (ton / fed.), fruit weight, fruit size, fruit length, fruit diameter, fruit firmness, total soluble solids (TSS %) and total sugars compared with that of the control in both seasons of study. Shoot girdling (3y.) significantly gave the highest increase of spurs number, number of fruits per tree, fruit weight, fruit size, fruit firmness, total soluble solids (TSS %) and the reducing sugars, while, it gave significant decrease in fruit acidity % in both seasons of study.

“…Strangulasi meningkatkan kandungan karbohidrat pada daun bagian atas luka (Thamrin et al, 2009;Susanto et al, 2016). Aplikasi girdling juga terbukti meningkatkan konsentrasi karbohidrat di bawah bagian luka (Raffo et al, 2011;Magda et al, 2015) dan beberapa minggu sebelum berbunga mengurangi absisi pada buah jeruk dan meningkatkan kandungan klorofil (Rivas et al, 2008). Adanya kandungan klorofil yang tinggi ini akan meningkatkan fotosintat yang terbentuk pada bagian atas strangulasi.…”
