Other claims from this paper (19)
- Observation Freshly mature Gynostemma seeds had 91% viability.
- Observation Germination under stated constant and alternating temperatures was below 10%.
- Association Viability significantly exceeded germination percentage, indicating fresh seed dormancy.
- Observation The Gynostemma embryo was fully developed.
- Observation Excised Gynostemma embryos germinated at (78.0±4.8)%.
- Observation Excised embryos produced normal seedlings and were judged non-dormant.
- Intervention effect Whole-seed water extract inhibited cabbage seed germination, seedling height and root length.
- Intervention effect Crushed-seed water extract inhibited cabbage seed germination, seedling height and root length.
- Association Extract inhibition strengthened significantly as concentration increased.
- Intervention effect Crushed-seed extract was more inhibitory than whole-seed extract.
- Intervention effect At 5% crushed-seed extract, cabbage germination was 18.0%, 77.1% below control.
- Intervention effect At 5% crushed-seed extract, cabbage seedling height was 0.1cm, 97.3% below control.
- Intervention effect At 5% crushed-seed extract, cabbage root length was 0.1cm, 95.8% below control.
- Mechanism Water-soluble inhibitors in seed coat and endosperm were inferred to cause dormancy.
- Intervention effect GA3 did not improve Gynostemma germination.
- Intervention effect 6-BA did not improve Gynostemma germination.
- Intervention effect Cold stratification promoted Gynostemma seed dormancy release.
- Observation Gynostemma seed dormancy was classified as non-deep physiological dormancy.
- Recommendation Low-temperature dry storage was recommended for conservation and dormancy breaking.
