| T1 |
0-98 |
Sentence |
denotes |
An evaluation of 2,5-norbornadiene as a reversible inhibitor of ethylene action in deepwater rice. |
| T2 |
99-310 |
Sentence |
denotes |
Partial submergence of deepwater rice (Oryza sativa L. cv Habiganj Aman II) elicits three responses: enhancement of internodal elongation, inhibition of leaf growth, and promotion of adventitious root formation. |
| T3 |
311-399 |
Sentence |
denotes |
All three responses can be induced in isolated stem sections by treatment with ethylene. |
| T4 |
400-546 |
Sentence |
denotes |
Dose-response curves indicate that the responses are linearly related to the logarithm of the ethylene concentration over two orders of magnitude. |
| T5 |
547-794 |
Sentence |
denotes |
Application of the cyclic olefin 2,5-norbornadiene (NBD) to ethylene-treated sections results in a parallel shift in dose-response curves to higher ethylene concentrations, indicating that NBD behaves as a competitive inhibitor of ethylene action. |
| T6 |
795-911 |
Sentence |
denotes |
Internodal elongation of stem sections is promoted by gibberellic acid (GA(3)) in the absence of exogenous ethylene. |
| T7 |
912-1048 |
Sentence |
denotes |
Endogenous ethylene levels do not increase in GA(3)-treated sections, and application of NBD does not prevent GA(3)-promoted elongation. |
| T8 |
1049-1145 |
Sentence |
denotes |
To the contrary, NBD treatment results in increased growth at intermediate GA(3) concentrations. |
| T9 |
1146-1256 |
Sentence |
denotes |
These results support the idea that ethylene acts through endogenous GA in promoting growth in deepwater rice. |
| T10 |
1257-1341 |
Sentence |
denotes |
NBD applied to GA(3)-treated stem sections results in increased ethylene production. |
| T11 |
1342-1533 |
Sentence |
denotes |
This enhancement of ethylene formation is reversed by application of either ethylene or propylene, indicating that ethylene biosynthesis in rice internodes is under negative feedback control. |
