Interactions between root restriction, irrigation and rootstock treatments on the growth and cropping of ‘Queen Cox’ apple trees: Effects on orchard growth and cropping

The relationship of hydraulic conductance to root system characteristics of peach (Prunus persica) rootstocks

“…Mandre et al (1995) also found differences in dry matter distribution with root confinement in peach trees. Similar responses to root confinement were also reported in the field by Webster et al (2000) and Williamson and Coston (1990) in peach and apple trees, respectively. More importantly, Webster et al (2000) observed that apple rootstocks did not have an effect on tree growth when trees were grown in containers despite their differences in vegetative growth potentials under normal field conditions.…”

More importantly, Webster et al (2000) observed that apple rootstocks did not have an effect on tree growth when trees were grown in containers despite their differences in vegetative growth potentials under normal field conditions. Therefore, it is very possible that root confinement was an overriding factor limiting the growth of the trees in this experiment that prevented the trees from exhibiting the differences in growth normally associated with these rootstocks.…”

Effects of temperature and solar radiation on sap flow in dwarfing apple rootstocks

“…Sap flow was influenced by root mass ( Figure 3B). Webster et al (2000) observed that restriction of the roots greatly reduced the extension growth of shoots in trees grafted on a vigorous rootstock. Moreover, many studies have suggested that the root system accounts for most of the resistance to water flow throughout the tree, in apple (Olien and Lakso, 1986;Cohen and Naor, 2002;Atkinson et al, 2003), in olive (Nardini et al, 2006), and in peach [Prunus persica (L.) Batsch; Basile et al, 2003].…”

Effects of a deep container on morpho-functional characteristics and root colonization in Quercus suber L. seedlings for reforestation in Mediterranean climate

“…The range of K R-LA data shown in this work is similar to those presented in other studies on young Q. suber plants by . Several works have pointed out that any root restriction on water conduction can affect plant vegetative growth and morphological characteristics (Tschaplinski and Blake, 1985;Webster et al, 2000). In fact, seedlings developed in CCS-18 presented lower shoot and root biomass than seedlings in CCL-30.…”
