“…Cotton drought tolerance begins to decline from the early germination stage, it reaches its lowest level at the bud stage followed by a gradual increase until it reaches a stable level at the real leaf stage (Zhang et al, 2007). The sensitivity of cotton plants to drought stress at the flowering and boll development stages have previously been reported (Turner et al, 1986). Therefore, identification of QTLs at the bud, flowering, and full boll stages will contribute greatly to marker assisted breeding of drought tolerant cotton cultivars.…”

ABSTRACT. Cotton is one of the most important natural fiber crops in the world. Its growth and yield is greatly limited by drought. A quantitative trait locus (QTL) analysis was therefore conducted to investigate the genetic basis of drought tolerance in cotton (Gossypium spp) using 188 F 2:3 lines developed from an inter-specific cross between a wild cotton species, G. tomentosum, and an upland cotton, G. hirsutum (CRI-12). A genetic map was constructed using 1295 simple sequence repeat markers, which amplified 1342 loci, distributed on 26 chromosomes, covering 3328.24 cM. A field experiment was conducted in two consecutive years (2014 and 2015) and 11 morphological and physiological traits were recorded under water-limited (W1)/wellwatered (W2) regimes at three growth stages (bud, flowering, and full boll). The traits measured included chlorophyll content, plant height, leaf area, leaf number, leaf fresh weight, leaf dry weight, boll weight, number of bolls per plant, and the number of fruiting branches. Sixtyseven and 35 QTLs were found under the W1 and W2 conditions, respectively. Of these, the majority exhibited partial dominance or over-dominance genetic effects for increasing the trait values. Four consistent QTLs were found under the W1 treatment on chromosomes 5, 8, 9, and 16, whereas no consistent QTL was found in W2. Thirteen QTL clusters were also identified on nine chromosomes (2, 3, 5, 6, 9, 14, 15, 16, and 21). These results will help to elucidate the genetic basis of drought tolerance in cotton.

“…The reduction in leaf area due to salinity was reported earlier by Khan et al [17] in rice and Chookhampaeng [6] in pepper plant. Drought stress reduces cell and leaf expansion, stem elongation, and leaf area index ( [34], [4], [10]). The reduction in leaf area was attributed due to the increasing in leaf senescence and reduced size of leaves developed due to low turgor under saline and water stress conditions.…”

Leaf traits of three soybean genotypes viz., Galarsum, BD 2331 and BARI Soybean 6 were evaluated for their salt and water stress tolerance under the salinity levels of 0, 50 and 75 mM NaCl and water stress with 70% depletion of available soil water at the Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Salna, Gazipur, Bangladesh. The treatment were imposed in plants on 21 days after emergence and continued up to 56 days of age. The results of this study indicated that leaf traits like leaf number, leaf area and its dry weight of the soybean genotypes were sharply decreased when the plants were exposed to water stress, salt stress and, combined salt and water stress conditions. Least reduction in leaf traits was observed in Galarsum in all stress conditions. All leaf traits decreased more in 75 mM NaCl salinity combined with water stress treatment. The leaf dry weight was decreased to 39.72, 38.58 and 39.43% of the control in Galarsum, BD 2331 and BARI Soybean 6, respectively. The genotype Galarsum also accumulated lower amount of Na + and higher amount of K + in leaf tissues under salt stress and, combined salt and water stress environments as compared to others.

“…However, as a result of its domestication and cultivation as an annual crop, modern cultivars are characterized by sensitivity to drought since the effectiveness of stress alleviation mechanisms is closely related to its indeterminate growth habit [7]. Even though debate still exists on which stage of development cotton is most susceptible to water stress, limited supply of water during flowering and boll development has been reported to be very detrimental for yield [8][9][10][11]. Extensive research conducted to elucidate water-deficit stress effects on cotton, has focused mainly on leaf physiology and metabolism, with limited attention to cotton's reproductive units despite their great importance as yield determinants [12].…”

Polyamines, putrescine, spermidine and spermine are low molecular weight polycations implicated in flowering and seed set and plants' responses under adverse environmental conditions. Research in other crops has shown that polyamine metabolism is greatly affected by water-deficit stress, however, no information exists on cotton (Gossypium hirsutum L.). A field study was conducted in 2011 in two contrasting locations (Fayetteville, AR, and Lubbock, TX) in order to investigate the effect of water-deficit stress during flowering on polyamine metabolism of the cotton flower and its subtending leaf. Treatments consisted of control (well watered) and water-stress (irrigation withheld for two weeks at the onset of flowering) in a split plot design. First day white flowers and their subtending leaves were collected at the end of each week of the stress period for determination of polyamine concentrations. Water-deficit stress resulted in significant increases in PUT and SPD levels of pistils and leaves compared to the control. However, pistil and leaf SPM content significantly increased under drought conditions in one location and remained unaltered in the other one. Leaf and pistil polyamine metabolism of cotton appeared to be greatly affected by limited water supply, however further research is needed to elucidate the ways polyamines can be used to increase cotton drought tolerance.
