“…Similar morphological changes including decreased root and vegetative dry weight, root length, branching, stem diameter, and plant height to root restriction were observed for different plants including winter wheat (Triticum aestivum L.) (Peterson et al 1984), bean (Phaseolus vulgaris L.) (Carmi & Heuer 1981;Carmi 1993), cucumber (Cucumis sativus L.) (Robbins & Pharr 1988;Kharkina et al 1999), tomato (Lycopersicon esculentum L.) (Peterson et al 1991;Kemble et al 1994;Bar-Tal et al 1995), summer squash (Cucurbita pepo L.) (NeSmith 1993), watermelon (Citrillus lanatus L.) (Liu & Latimer 1995), sitka spruce (Picea sitchensis L.) (Townend & Dickinson 1995), common plantain (Plantago major) (Whitfield et al 1996), salvia (Salvia splendens L.)

“…Other studies have also suggested that root restriction may affect shoot growth through additional metabolism processes (Krizek et al 1985;Ismail & Noor 1996). For example, root restriction might alter plant water balance and consequently affect leaf growth (Hameed et al 1987;Peterson et al 1991). It has also been proposed that the reduction of plant growth under root restriction may be caused by a decrease in the synthesis and translocation of growth substances from the roots (Richards & Rowe 1977;Carmi & Heuer 1981 ;Ismail & Davies 1998).…”

Many experiments are conducted in simulated confined spaces to provide controlled environments where plants are grown in pots with limited rooting volume to characterise fundamental physiological responses of plants to stress conditions such as soil water, soil salinity, irrigation water salinity, and plant nutrition. However, rooting volume in the pots can have a limiting effect on overall plant growth to varying degrees. This study was undertaken to quantify the effects of widely differing rooting volume on growth, yield, and water use of eggplant (Solanum melongena) and okra (Abelmoschus esculentus). Eggplant and okra experiments were conducted similarly, but as separate experiments. Both plants were grown in 3.6-litre (P1), 16-litre (P2), 36-litre (P3), and 52-litre (P4) pots. For eggplant and okra, evapotranspiration (ET) and all of the growth parameters including plant height, stem diameter, root and vegetative dry weight, root length, number of branches and fruit, and fruit yield significantly increased with increasing rooting volume. Pot volume started to affect plant height and ET after 3 weeks from transplanting. For both experiments, the highest yield and the highest yield based water-use efficiency (WUE yield ) were obtained from the P4 and P3 treatments, respectively. The highest WUE based on total biomass (WUE biomass ) was obtained from the P4 and P3 treatment of eggplant and okra, respectively. Both experiments exhibited similar morphological changes such as decreases in plant height, stem diameter, branching, root and vegetative dry weight, and root length to root restriction. As a result of this study it can be concluded that a pot size of 36 litres (P3) may be enough for okra growth, but even a 52-litre (P4) pot size may not provide unrestricted rooting volume for eggplant growth.

“…Increased substrate volumes and two months of the seedling in the nursery caused larger quantity, length and fresh weight of roots (Table 2). However, in tomato this large amount of roots at the transplant were physiologically inactive as shown by Peterson et al (1991) who indicate that restriction of the roots caused by a reduced volume in the nursery provoke loss of primary and post-transplant roots, increases the number of secondary and adventitious roots, which are physiologically more active.…”

“…For example, it is known that plant growth and morphology, including both roots and shoots, can be modified by the volume available for root growth, independent of nutrition or moisture stress (e.g. Krizek et al 1985;Peterson et al 1991aPeterson et al , 1991b. The difficulties are accentuated when exploring root system traits that are expressed or become important later in the life cycle, such as around flowering or during grain filling, because of the limitations imposed by soil volume.…”

Abstract. There is little consensus on whether having a large root system is the best strategy in adapting wheat (Triticum aestivum L.) to water-limited environments. We explore the reasons for the lack of consensus and aim to answer the question of whether a large root system is useful in adapting wheat to dry environments. We used unpublished data from glasshouse and field experiments examining the relationship between root system size and their functional implication for water capture. Individual root traits for water uptake do not describe a root system as being large or small. However, the recent invigoration of the root system in wheat by indirect selection for increased leaf vigour has enlarged the root system through increases in root biomass and length and root length density. This large root system contributes to increasing the capture of water and nitrogen early in the season, and facilitates the capture of additional water for grain filling. The usefulness of a vigorous root system in increasing wheat yields under water-limited conditions maybe greater in environments where crops rely largely on seasonal rainfall, such as the Mediterranean-type environments. In environments where crops are reliant on stored soil water, a vigorous root system increases the risk of depleting soil water before completion of grain filling.Additional keywords: root biomass, root length, root length density, root system size, water capture.
