The aim of this study was to investigate the effect of waterlogging on morphological and physiological traits of sorghum (Sorghum bicolor L. Moench) cultivars. Four sorghum cultivars, cv. Wray, Keller, Bailey (sweet cultivar) and cv. SP1 (forage cultivar) at five expanded leaf stage were subjected to 20 days of waterlogging and drained pots were kept as the control. Twenty days of waterlogging did not cause a significant difference in shoot and root biomass among cultivars. Flooding reduced leaf area (69%), plant height (30%) and youngest leaf expansion rate of all cultivars but severely reduced in SP1 (35-80%). Flooding promoted leaf senescence of all cultivars and biomass allocation to shoot (increase in shoot/root) in Wray, Keller and Bailey, but increased biomass partitioning to root in SP1. The initiation of new nodal root was noted in SP1, whereas the ability to maintain root surface area by increase in longest root length and nodal root development near soil surface was found in Wray. Photosynthetic rate, stomatal conductance and transpiration rate were severely reduced under waterlogging conditions of sweet cultivars (65-78%), but enhanced over the control in forage cultivar (56%). The ability to conserve root surface area, allocate more biomass to shoot during waterlogging and develop root near soil surface may support new growth in Wray, whereas the ability to maintain leaf gas exchange parameters in SP1 was due to the active nodal root growth. Nevertheless, there was no relationship between photosynthetic rate and shoot growth of sorghum under anaerobic conditions.

“…The ability to sustain leaf growth under prolonged flooding conditions (extended from 30 DAE) may be facilitated by the active nodal and lateral root growth and aerenchyma formation in roots, plant's axes and stalk base. The development of adventitious or nodal roots has been previously reported to support leaf growth of waterlogging tolerant soybean (Henshaw et al, 2007) and buckwheat (Matsuura et al, 2005).…”

“…In water-loving species, intercellular gas-filled spaces that often extend from the shoots to near the root tips could enhance transport of oxygen, carbon dioxide and ethylene between plant parts above water and submerged tissues (Armstrong, 1979;Laan et al, 1990). The ability of plants to produce adventitious roots and nodal roots and aerenchyma formation in roots are important characters for flooding-tolerant crops (Orchard & Jessop, 1985;McDonald et al, 2001McDonald et al, , 2002Zaidi et al, 2003Zaidi et al, , 2004Matsuura et al, 2005;Mano et al, 2006;Henshaw et al, 2007;Kubo et al, 2007). Glaz et al (2004) also reported aerenchyma formation in stalks that supports internal gas spaces resulting in enhanced cane yield and sucrose yield in sugarcane.…”

Moench) AbstractUnderstanding the responses of sweet sorghum to flooding and the characters associated with flooding tolerance may be a useful strategy for pre-rice production and help meet demand for biofuel feedstock. Three sweet sorghum genotypes (Bailey, Keller and Wray) and five flooding treatments including non-flooding control, continuous flooding extended from 30, 45, 60 and 75 days after emergence to harvest were conducted under greenhouse conditions. Flooding decreased leaf dry weight (22Á60%), leaf area (10Á70%), number of node per stalk (1Á5%), shoot dry weight (5Á20%) and stalk yield (2Á22%) with highest reduction in 30 days after emergence flooding treatment. Flooding later than 30 days after emergence did not significantly affect shoot growth, yield and yield components. Brix value, sucrose content and total sugar content were not significantly affected. All studied cultivars had similar shoot growth response. Flooding induced development of roots in water; root length, root dry weight, nodal root and lateral root number and interconnection of aerenchyma spaces from roots in flooded soil to stalk base above water level but suppressed root growth in flooded soil. The acclimation traits were highest in Keller, flooding from 30 days after emergence but there was a lack of root development in 75 days after emergence flooding treatments. These findings indicate the effect of waterlogging on sweet sorghum growth and yield strongly depends on the growth stage at which it occurs. There were genetic variations in root morphological and anatomical responses to flooding of sweet sorghum. The development of nodal and lateral roots and aerenchyma formation from flooded plant parts to stalk bases above water level may distribute to flooding tolerance in sweet sorghum. Based on the results, a flood-free period of at least 30 days after emergence is required to sustain yield of pre-rice sweet sorghum and early planting is highly recommended.

“…It is amusing that the genotype BINAmasur1 showed drastic reduction in number of leaves during flooding compared to control, but this did not appear as constant declining in number of leaves as observed in other genotypes. Matsuura et al (2005) found that the number of leaves in buckwheat plant was significantly reduced by waterlogging stress to 60% of the control. The number of leaves per plant during flooding and after termination of flooding also reduced significantly in mungbean plant at vegetative stage (Ahmed et al, 2002).…”

The experiment compared the relative tolerance of some advanced lines and a variety of lentil viz. BD3859, BD3905, BD3867, ILL5087, ILL5133 and BINAmasur1 (variety) to soil flooding. The growth rates of the genotypes considerably reduced when flooding imposed at vegetative stage. However, the genotypes responded differently to flooding onward during recovery period. Leaf and roots showed highly vulnerable to flooding. Flooding promoted extensive leaf senescence and desiccation. Flooding induced damaging of root system was highly striking, despite there existed remarkable recoveries in some genotypes. The adverse effect of flooding was less pronounced on stem than other plant components. However, shoot growth reduction was 76-86% relative to control. Relative growth rate (RGR) of most plant components showed negative rate during flooding, but it varied from negative to positive during recovery period. Considering total plant biomass, flooding tolerance (FT) indices indicated that BINAmasur1 and BD3859 had comparatively better degree of tolerance to excess water. In contrast, ILL5133 and ILL5087 were susceptible to flooding for having negative FT indices.
