“…These soils, when flood irrigated, expose crops (such as cotton, Gossypiurn hirsutum L.) to a period of waterlogging during and for some time after irrigation (Mason et al, 1984). Cotton subjected to waterlogging usually has reduced yield (de Bruyn, 1982;Hodgson and Chan, 1982) with the decrease being proportional to the time of inundation (up to 32h) at each irrigation (Hodgson, 1982).

Surface-irrigated cotton (Gossypium hirsutum L.) grown on slowly draining clay soil is subjected to short-term periods of waterlogging at each irrigation which generally results in reduced productivity. The sequence of above-and below-ground plant responses to transient waterlogging and the role of N availability in modifying the immediate responses were studied. Lysimeters of Marah clay loam (a Natrustalf) were instrumented to monitor soil and plant responses to a 7-day waterlogging event beginning 67 days after sowing. Cotton ('Deltapine 61') plants (8 per lysimeter) were grown with two levels of added N (300 kg ha and 30kg ha -I) and two irrigation treatments (flooded and control). Measured soil-O2 levels decreased rapidly upon surface flooding because water displaced air and root zone respiration consumed 02. The rate of 02 consumption was 2.7 times greater in the high-N treatment than the low-N treatment. This difference was associated with a 1.8 fold difference in numbers of observed roots. Root growth was only slightly affected by flooding. Leaf growth decreased by 28%, foliage temperature increased 2.3% and apparent photosynthesis decreased by 16%. It is suggested that flooding reduced photosynthetic activity within 2 days while other stress symptoms became apparent after about 6 days. Although this stress was reflected in a trend for decreased plant productivity, the effect of flooding on boll dry mass at harvest was not significant at the level of replication used. The single waterlogging did not cause yield reductions comparable to those observed elsewhere when several waterlogging events were imposed.

“…When grown as an irrigated crop, cotton will often experience a set-back in growth after an irrigation, for cotton has a low tolerance to waterlogging [3,14]. This intolerance may be due to the low-oxygen environment that results from waterlogging, for it has been demonstrated that cotton is susceptible to anaerobic conditions, even more so than soybean [15].…”

We report here the initial characterization of the alcohol dehydrogenase (Adh) gene family of the allotetraploid Gossypium hirsutum, a crop plant that is highly sensitive to waterlogging. Twelve Adh cDNAs were isolated from a library constructed from RNA prepared from anaerobically stressed root tips. Nine of the twelve cDNAs fell into one class, while each of the other three cDNAs fell into a separate class. The 3'-untranslated regions had little or no homology between classes implying that each of these four classes is encoded by a different gene. The most abundant class of Adh cDNA was expressed under the control of the 35S promoter in transgenic cotton and encodes the ADH2 isozyme, the isozyme induced most strongly by low oxygen conditions. Cotton Adh genomic segments were sequenced. The promoter regions of these Adh genes contain the cis-acting motifs which have been shown in other plant species to be necessary for anaerobic induction of transcription. A gene conversion event is likely to have occurred between the 3' ends of two of the genes. Sequence comparison of the Adh genomic and cDNA clones, and Southern analysis of genomic DNA suggest the existence of multiple copies of Adh genes in cotton. Five different members of this Adh gene family of cotton have been identified, of which four are very similar.

It is, however, important that the cotton plant is not water logged in this process, because this may induce stress conditions which will inhibit yields (De Bruyn 1982;Reicosky et al 1985 a;Reikosky et al 1985b).…”

The relative sensitivity to plant water stress during the reproductive phase of upland cotton (Gossypium hirsutum L.)

The relative sensitivity of the cotton plant to water stress throughout the growing season was determined to identify when irrigation will have the greatest beneficial effect. Daily plant water stress for 72 different data sets of water applications was correlated to corresponding yield criteria. The magnitude of significant correlation was interpreted as the degree of sensitivity. Plant water stress during square formation and early flowering resulted in fewer bolls to reach maturity, but this detrimental effect was cancelled by the development of bigger bolls due to greater lint growth. This resulted in better seedcotton and lint yields. Flower and boll senescence which resulted from water stress during flowering peak, however, inhibited seedcotton and lint yields. The most pronounced inhibiting effect stress had on yields, was during boll development well after the end of effective flowering, when it inhibited boll development. Stress during ripening of the bolls increased lint and boll development and consequently enhanced yields. When limited quantities of water is available, preference should be given to irrigation during boll development, then by irrigation when the first flowers appear, followed by irrigation during peak flowering. Water should be withheld from opening of the first bolls.
