e0“glyphosate-resistant (GR) cotton”
e6“The GA treatments to glyphosate-treated plants increased the anther–stigma distance 12-fold, stigma height, and pollen viability in the second week of flowering but decreased the number of seeds in second-position bolls on Fruiting branches 1 through 3, decreased the number of first-position bolls per plant, and increased the number of squares in comparison with glyphosate-treated GR plants not receiving GA. Although GA applications to glyphosate-treated GR cotton have some remedial effect on pollen viability, the GA-induced increase in the anther–stigma difference exacerbates the increase in anther–stigma distance caused by glyphosate, resulting in low pollination”

Other claims from this paper (12)
- Intervention effect Glyphosate applied at the four-leaf POST stage lowered pollen viability in GR cotton by 51 in the first week of flowering compared with untreated GR plants.
- Intervention effect Glyphosate applied at the four-leaf POST stage lowered pollen viability in GR cotton by 38% in the second week of flowering compared with untreated GR plants.
- Intervention effect Seed set per boll was significantly reduced when the pollen donor parent was glyphosate treated compared with untreated, in the first 2 weeks of flowering.
- Intervention effect Glyphosate treatments applied to male parents did not significantly change seed set at weeks 3 and 4 of flowering.
- Intervention effect Glyphosate treatments applied to female parents did not influence seed set at any time.
- Intervention effect Glyphosate treatment of male parents reduced boll retention from crosses during the first and third week of flowering.
- Intervention effect Glyphosate treatment of female parents did not affect boll retention from crosses.
- Intervention effect Gibberellic acid applied to glyphosate-treated GR cotton increased stigma height and pollen viability in the second week of flowering.
- Intervention effect Gibberellic acid applied to glyphosate-treated GR cotton decreased the number of seeds in second-position bolls on fruiting branches 1 through 3.
- Intervention effect Gibberellic acid applied to glyphosate-treated GR cotton decreased the number of first-position bolls per plant.
- Intervention effect Gibberellic acid applied to glyphosate-treated GR cotton increased the number of squares.
- Mechanism The gibberellic acid-induced increase in anther-stigma difference exacerbates the glyphosate-caused increase in anther-stigma distance, resulting in low pollination.
