Other claims from this paper (18)
- Observation Dry lettuce seeds had no detectable PAL activity.
- Observation PAL became detectable within 4 hours of imbibition under white light.
- Observation PAL specific activity increased rapidly over the next 12–16 hours.
- Intervention effect Far-red light suppressed germination.
- Intervention effect Far-red light suppressed PAL development.
- Intervention effect GA3 caused almost complete dark germination without proportionate PAL increase.
- Intervention effect GA3 did not induce proportionate increases in PAL.
- Intervention effect CHDC inhibited germination in light and dark.
- Intervention effect CHDC inhibited PAL activity in light and dark.
- Intervention effect GA3 retarded radicle elongation in light.
- Intervention effect Benzyladenine retarded radicle elongation in light.
- Observation PAL activity declined concurrently.
- Intervention effect Benzyladenine reversed CHDC effects on germination.
- Intervention effect PAL activity remained highly reduced with benzyladenine after CHDC.
- Intervention effect Transfer from white light to far red severely inhibited subsequent PAL increase.
- Intervention effect Transfer from white light to far red severely inhibited radicle growth.
- Association PAL induction was suggested to coincide with seed germination.
- Association PAL amount per germinated seed was related to embryonic axis elongation.
