“…In oilseed rape, following winter dormancy, new leaves emerge and the rapeseed plant develops a single stalk from the crown, with most of the seed pods developing on the branches. Plants with indeterminate growth habit are known to be very flexible in their responses of growth and yield to water stress and different environmental conditions (De Costa et al 1997;Black et al 2000;Boutraa and Sanders 2001). This is consistent with the response of oilseed rape in our experiments, where the formation of longer branches and more sub-branches resulted in more pods when water stress was alleviated.…”

Root foraging and yield components underlying limited effects of Partial Root-zone Drying on oilseed rape, a crop with an indeterminate growth habit

We report on two experiments with oilseed rape (Brassica napus L.) to test if partial root-zone drying techniques improve yield in a crop in which vegetative and reproductive growth overlap (indeterminate growth habit), and to investigate what plant morphological responses contribute to the yield that is realized. Deficit irrigation resulted in smaller plants with smaller yields but larger seeds compared to treatments with shallow groundwater (first experiment) and with fully watered conditions (second experiment). Different partial root-zone drying treatments (water supply patterns) under deficit irrigation, however, had little effect on plant growth and yield components (number of branches, branch lengths, number of pods, etc.). Our results suggest that partial root-zone drying doesn't work well with oilseed rape. Detailed measurements of soil water contents and root distribution indicate that roots were extremely plastic, effectively foraging for water, and these root responses may have overwhelmed physiological effects of partial root drying on the shoot. Furthermore, in crops with indeterminate growth with a short vegetative growth phase, partial root-zone drying may be ineffective in enhancing the major yield components. Further reasons for the lack of success are discussed.

“…The life stage was similar from year to year; however, the intensity, duration, and rate of the stress varied considerably (Supplemental Table S1). Similar terminal drought stress observations have been documented in other plants such as faba bean (Vicia faba L.), as it has been determined that the greater flexibility offered by an indeterminate growth habit can exploit midseason water inputs (De Costa et al, 1997). It has been noted that, in plants with little to no freezing tolerance on the morning after the frost, the injured plant looks flaccid and water soaked, as cell membranes have lost their semipermeability and the intracellular compartmentalization is destroyed (Burke et al, 1976).…”

“…The stage of our plants, the unifoliate leaf stage and the first trifoliolate leaf stage, were found to be the most sensitive to subzero temperature stress in common bean . To the best of our knowledge, no data have been published analyzing the response of tepary bean to water logging, although high water availability is known to cause excessive vegetative growth in indeterminate plants (De Costa et al, 1997), a growth habit common to the tepary beans in this trial. Survival rates varied among the four trials analyzed (Fig.…”

“…Tepary beans often did better under the mild to moderate stress conditions than the irrigated conditions, suggesting either that excessive irrigation hampers tepary bean performance or that stress signals encourage indeterminacy of tepary bean, resulting in increased reproduction. To the best of our knowledge, no data have been published analyzing the response of tepary bean to water logging, although high water availability is known to cause excessive vegetative growth in indeterminate plants (De Costa et al, 1997), a growth habit common to the tepary beans in this trial. Bean plants with indeterminate growth habits have an inherent flexibility in quantity of flowers formed (Nleya et al, 1999), which allows the plant to take advantage of opportune times for growth and reproduction while delaying these processes during inopportune conditions.…”

Successful Introgression of Abiotic Stress Tolerance from Wild Tepary Bean to Common Bean

Common bean (Phaseolus vulgaris L.) production is limited due to abiotic stresses, including drought and subzero temperatures. Tepary bean (P. acutifolius Gray), a relative of common bean, has been reported to be tolerant to these stresses. Preliminary studies screening wild tepary accessions for cold tolerance demonstrated that W6 15578 is a potential donor of cold tolerance, so an interspecific backcross population derived from a cross between it and common bean (NY5‐161) was developed. A 3‐yr field study was conducted in Saskatoon, SK, to identify lines able to withstand subzero temperatures better than the common bean parent at the seedling stage. Introgression lines were also tested for response to terminal drought under field conditions in Isabela, PR, over 3 yr. Days to flowering and yield measurements, along with subzero temperature and drought stress tolerance data, are presented. Although the interspecific introgression lines were backcrossed twice to common bean to improve the fertility and increase the proportion of common bean genome, several introgression lines performed better than the common bean parent under both stress conditions. Future breeding objectives include backcrossing to tepary to try to recover additional abiotic stress tolerance genes, as well as using selected introgression lines as breeding material to develop common bean varieties with increased subzero temperature stress and drought stress tolerance. Interspecific introgression of portions of the tepary bean genome into common bean is a promising method for increasing abiotic stress tolerance in common bean.

“…The reduction in leaf area is a typical characteristic of drought-avoider plants (Quilambo 2000), which cope with moisture-deficit stress through increasing water acquisition or conservation of water, which otherwise may have been lost through transpiration. The reduction in leaf production and leaf area expansion rate, in response to moisture stress, has been reported elsewhere (Norris 1982;De Costa et al 1997). Similarly, although plant responses to moisture stress decreases leaf size, considerable genetic variation is expected between plants of the same or different species (McCree and Davis 1974;Yao et al 1988).…”

The effects of moisture stress were evaluated in four Indigofera species (I. amorphoides, I. arrecta, I. coerulea and I. vicioides) using a pot experiment under glasshouse conditions. The aim was to examine the influence of moisture-deficit stress on physiological attributes and performance of the four Indigofera species. Based on plant available water (PAW) levels, three moisture levels were applied (no stress or 70-100% PAW, 40-70% PAW and 10-40% PAW) as experimental treatments and imposed on each species in a randomised complete block design with four replications. Moisture stress significantly reduced (p < 0.05) the total leaf area of I. amorphoides at moderate levels and that of I. vicioides at the most severe moisture stress level. The relative growth rate was significantly reduced (p < 0.05) in I. amorphoides but not in I. arrecta, I. coerulea or I. vicioides plants subjected to moisturedeficit stress. The reduction in total dry matter yield was due to the effect of moisture stress in reducing both leaf area and leaf area ratio. Drought stress-tolerance indices were not different (p > 0.05) for I. arrecta or I. coerulea grown under no stress and moisture-deficit stress conditions. The root mass fractions of I. amorphoides and I. arrecta were substantially increased (p < 0.05) due to moisture stress. Water-use efficiency was low in I. amorphoides under water deficit conditions, while that of I. vicioides was higher under severe stress conditions compared to non-stress conditions. Transpiration efficiency was, however, higher at moderate moisture-deficit stress levels than under non-stressed or severely stressed plants. Generally, the species investigated exhibited significant variation in terms of physiological attributes and performance response to moisture-deficit stress. Indigofera amorphoides was relatively sensitive while I. vicioides was able to maintain unabated growth under water stress conditions. This is highly relevant to programmes aimed at identifying suitable species as a source of fodder for livestock exposed to long dry seasons and frequent drought phenomena.
