“…Also, root pruning alone and combined with AMF increased shoot number indicating vigor restoration of older apple tree. While control treatment had a decrease in shoot numbers across horizontal and vertical plane, because root system substantially degraded unable to absorb sufficient nutrition for over ground parts, consistent with findings presented by Saure [2007] that older trees had altered root/shoot balance at expense of the roots and in turn inhibiting the shoot sprouting.…”

“…Light intensity had strong relationship with fruit yield, the insufficient light into control canopy decreased flower bud formation followed by fruit yield, which has been also reported in other apple orchards [Jung and Choi 2010]. Root pruning and shoot pruning could more inhibit shoot growth avoiding renewal heading in older apple trees [Saure 2007]. Shoot re-allocation treated by root pruning alone and combined with AMF might prevent shading among the limbs to maximize the light intensity within the canopy.…”

“…Results driven from this study implied that pruned root was nicely compatible with AMF and only in this way the function of arbuscular mycorrhizal symbiosis for older apple tree growths was well realized. Root pruning is recommended for rootballed trees to produce trees capable to rapid root regeneration and also advocated to inhibit shoot growth for restoring the root to shoot balance [Catherine et al 1997, Saure 2007. Actually, the acceptance of root pruning in reduction shoot growth in commercial fruit production is now still rather limited Fig.…”

“…In several long-term experiments the main objective of root pruning, the reduction of shoot growth, was only reached in some years but not in others, or was not achieved at all [Ferree 1992, Autio and Greene 1994, Miller 1995. Also, little is known about how the varying effects are brought about, and what could be done to adjust root pruning-if possible to special situation for proper results [Saure 2007]. Normally, new roots produce at the cut end to substitute for the original old ones, ultimately providing absorption and anchorage plants.…”

Older apple trees often demonstrate physiologically unreasonable shoot distribution due to root system aging, which results in lower fruit yield and poor fruit quality. Therefore this study was conducted to test whether root pruning combined with arbuscular mycorrhizal fungi could restore growth potential of fortyyear-old Red Fuji apple trees (Malus × domestica Borkh.) in a commercial orchard in 2013, by root pruning along both sides of rows, 80 cm from the trunk, to a depth of 30 cm and application of 100 ml arbuscular mycorrhizal inoculum per plant. Results showed that the percentage of root colonized by mycorrhizal fungi increased as root pruning was combined with arbuscular mycorrhizal fungi, however mycorrhizal colonization was not seen in the control roots and roots only by root pruning. For control tree total number of shoots decreased by 28.22% in 2015 than in 2013 and shoots mainly distributed in the outer canopy accounting for 58.10% of the total, which caused the lower light intensity inside the canopy, followed by lower fruit yield and poor fruit quality. Compared to control plant, shoot reduced by 33.96 and 38.51% in the outer canopy but increased by 97.99 and 123.69% in the inner canopy in 2015, as well as 390.20 and 478.43% in the vertical height of 1.5 to 2.5 m canopy, respectively treated by root pruning alone and combined with arbuscular mycorrhizal fungi. Root pruning alone and combined with arbuscular mycorrhizal fungi also raised the relative light intensity by 38.71 and 60.26% in the inner canopy in 2015, subsequent fruit yield by 315.79 and 373.68% respectively, in comparison to control plant. Shoot re-distribution improved fruit quality such as increase in firmness and soluble solid. Data indicated that the effect of root pruning combined with arbuscular mycorrhizal fungi on the rejuvenation of older apple trees was stronger than root pruning alone. It is therefore concluded that root pruning combined with arbuscular mycorrhizal fungi can think of as a measure to renew the older apple trees.

“…Aynı araştırmacılar, budanmayanlara kıyasla kök budaması yapılan fidelerin dikim sonrasında da iyi tepki vermelerini daha yüksek nispi büyüme oranı ve fide gücüne bağlanmışlardır. Bu etkilerin ise genç kökler tarafından artan sitokinin üretiminin bir sonucu olabileceği belirtilmiştir (Saure, 2007). Kök budaması sonucu oluşan yeni kökler muhtemelen bol miktarda sitokinin üreterek fide gelişimini arttırmış ve baskılanan vejetatif gelişmeyi kısa sürede gidermişlerdir.…”

Plant growth regulator as chemical stopper application which is the most common practice in nurseries is practical in order to regulate height control and development on seedlings. However, the problems experienced after application of chemicals and the fact that the application is not organic brought up alternative control methods. This study was conducted in order to investigate the effect of different types of root pruning and chemical regulator application on cucumber (cv. Murat F1) seedling quality. Cucumber seeds were sown on 25.07.2017 in peat (vermiculite was used as only the cover) in styrofoam tray with 128 holes at a commercial seedling company under polyethylene covered greenhouse. After the germination room, seedlings were put in the seedling adaptation greenhouse and growth there until transplanting. When the seedlings reached 1-2 true leaves, applications were performed. In the experiment (1) 1/3 of the root was pruned from bottom, (2) 1/3 of root was pruned from side and they were compared with (3) the chemical regulator with paclobutrazol active ingredient (Cultar, Sygenta) which used very common by commercial seedling companies. Seedlings with (4) no application were tested as control. For each treatment, 3 styrofoam trays were used, and each tray was considered as 1 repetition. 16 days after the seed sowing, when seedlings were ready for transplanting stem and root length, leaf numbers, stem diameter, leaf color, fresh and dry weight of root and shot were measured. Obtained results show that the number of leaves, L, a*/b* and h° values did not changed with treatments, however, compared with chemical regulator, root pruning decreased root length, stem diameter, root and shoot fresh and dry weights. Chemical regulator application thickened the stem and increased plant biomass. It can be concluded that root pruning can be an alternative to the use of chemical regulator, the root pruning from side part can be used as a regulator because it creates a lower seedling biomass but the root pruning from bottom can be used because of its ease of application. ÖzetFideliklerde boy kontrolü ve gelişimi düzenlemek için kimyasal durdurucu uygulaması pratik olması nedeni ile en çok yapılan uygulamadır. Ancak durdurucu uygulanmış fidelerde dikim sonrası yaşanan sorunlar ve uygulamanın organik olmaması alternatif kontrol yöntemlerini gündeme getirmiştir. Yürütülen bu çalışmada farklı şekillerde yapılmış kök budamasının hıyarda (cv. Murat F1) fide kalitesine etkisi araştırılmıştır. 2017 yılının yaz döneminde özel bir hazır fide firmasına ait polietilen örtülü serada gerçekleştirilen çalışmada, hıyar tohumları 128 gözlü viyollerde torf ortamına ekilmiş (25.07.2017) ve vermikulit kapak olarak kullanılmıştır. Çimlendirme odasından sonra fide serasına alınan fidelerde 1-2 gerçek yapraklı dönemde uygulamalar yapılmıştır. Denemede (1) kökün alttan 1/3'ünün budanması, (2) kökün yandan 1/3'ünün budanması uygulamaları kullanılmış, (3) ticari fide firmalarının uyguladığı paclobutrazol etkili maddeli kimyasal durdurucu (Cult...
