e0“Higher than optimum temperatures during cotton's ( Gossypium hirsutum L.) growing season”
e1“The results indicated that high night temperatures had an immediate effect on leaf respiration rates and membrane damage by significantly increasing them compared to the control and a similar pattern was observed on leaf photosynthesis and ATP levels that were markedly decreased”
e4“Nevertheless, flower bud sucrose content was substantially increased under conditions of high night temperatures, while hexose content was decreased and starch concentrations remained unaffected”
e7“Growth chamber experiments were conducted using cotton cultivar ST 5288 B2RF”

Other claims from this paper (9)
- Intervention effect High night temperatures increased leaf respiration rates and membrane damage compared with the control.
- Intervention effect High night temperatures decreased leaf photosynthesis and ATP levels compared with the control.
- Intervention effect High night temperatures substantially increased leaf GR levels.
- Intervention effect High night temperatures left flower bud GR content unaffected.
- Intervention effect High night temperatures significantly decreased leaf hexose, sucrose and starch levels.
- Intervention effect High night temperatures increased flower bud sucrose content.
- Intervention effect High night temperatures left flower bud starch concentrations unaffected.
- Intervention effect Elevated night temperatures decreased the number of flower buds per plant and the dry weight of flower buds.
- Mechanism High night temperatures negatively affected cotton flower bud production, attributed to disrupted flower bud carbohydrate metabolism from an insufficient GR response.
