The Rate of Fiber Elongation Correlates with the Speed of Ethylene Production in Cultured Wild-Type Ovules after Various Treatments.

(A) Fiber growth curve obtained from cultured wild-type ovules after various treatments.

(B) Ethylene production from cultured wild-type ovules after various treatments.

Wild-type ovules were collected at 1 DPA and cultured for different periods as indicated. Data reported are means ± se of three independent experiments. A very small amount of ethylene always present in fl ovule culture that did not increase throughout the entire culture period was considered injury-related ethylene and was subtracted from all data reported here. For cultures of >6 d, we reinforced the culture with 50% of the initial amounts of C24:0, C16:0, or ACE on day 7.
