“…After incubation in sorbitol solutions, almost complete inhibition of the root growth was attained somewhere between -1.21 and -2.04 MPa. This is in agreement with the previously reported lowest Ow at which complete inhibition of root growth occurred in several plants (Gardner and Nieman 1964, Newman 1966, Logsdon et al 1987. At lower osmotic potentials, seedling roots probably could not osmoregulate, consequently, turgor was lost and growth completely inhibited.…”

“…A decrease in root growth at low soil water potentials has been reported by various workers (e.g. Salim, Todd & Schlehuber, 1965;Newman, 1966a;Briske & Wilson, 1980;King & Bush, 1985;Mackay & Barber, 1985;Stevenson & Laidlaw, 1985). This decrease in root growth has commonly been attributed to the fact that root elongation is in part a hydration process (e.g.…”

SUMMARYThree experiments using soil-grown Lolium perenne plants were performed in order to investigate the effects of a gradually increasing drought stress on the death of root cells and the growth of lateral roots. Water potentials of -2 to -10 MPa caused death of the root cortex, but death of root tips occurred only at soil water potentials helow -10 MPa. Low soil water potentials promoted lateral root initiation and elongation, the total length of lateral roots being between three and five times that of control plants. On rewetting severely droughted plants, root growth continued by elongation of existing, previously initiated, lateral roots.

“…PREGITZER et al (1993) tested the rooting response of trees growing in a mixed hardwood forest to water and nitrogen applied for 20 and 40 d and found the increase of available water over the 40-d duration resulted in greater root production than over the 20-d duration. Root growth of flax (Linum usitatissimum L.) also increased at higher soil moisture contents (NEWMAN, 1966). RHODENBAUGH and PALLARDY (1993) tested three hybrid poplar clones in their ability to grow in soils lacking and containing adequate water.…”

In addition to genetic control, responses to environmental stimuli affect the success of rooting. Our objectives were to: 1) assess the variation in rooting ability among 21 Populus clones grown under varying soil temperatures and amounts of precipitation and 2) identify combinations of soil temperature and precipitation that promote rooting. The clones belonged to five genomic groups ([P. trichocarpa Torr. & Gray x P. deltoides Bartr. ex Marsh] x P. deltoides ‘BC’; P. deltoides ‘D’; P. deltoides x P. maximowiczii A. Henry ‘DM’; P. deltoides x P. nigra L. ‘DN’; P. nigra x P. maximowiczii ‘NM’). Cuttings, 20 cm long, were planted in Iowa and Minnesota, USA, in randomized complete blocks at 1.2- x 2.4-m spacing across three planting dates during 2001 and 2002. Soil temperatures were converted to belowground growing degree days (GDD) (base temperature = 10°C) accumulated over 14 days. Genomic groups responded similarly for root dry weight, number of roots, total root length, and mean root length, that increased as belowground GDD increased. Belowground GDD and precipitation governed rooting throughout the 14-d growing period. A minimum of four days above 14°C, along with sufficiently dispersed precipitation (e.g. no more than 3 d without a precipitation event), were needed to sustain aboveaverage rooting. Therefore, we recommend using a base temperature of 14°C for future models estimating belowground GDD in northern temperate zones.
