- Intervention effect Thiamine application at moderate concentration promotes seed germination and increases the germination rate of old seeds.
- Association In germinating seeds, thiamine is consumed in the dark nearly in parallel to a decrease of dry weight.
- Intervention effect Artificial application of thiamine remarkably increased the rate of respiration.
- Association Thiamine content of old seeds decreased nearly in proportion to elapsed time, and germination rate is closely related to thiamine content.
- Intervention effect Foliar thiamine spray at moderate concentration is effective for initiation and development of roots and flower bud differentiation.
- Intervention effect Foliar thiamine spray at moderate concentration increased crop yield; larger tubers and weighty pods were produced.
- Intervention effect Foliar thiamine spray at moderate concentration improved the flavor of crops.
- Recommendation The optimum thiamine solution concentration for seed soaking and foliar spray is about 1 ppm.
- Intervention effect Foliar thiamine spray is more effective in the first half of the growing period than in the latter half.
- Intervention effect Under unfavorable light, temperature and fertilizer conditions, thiamine application is especially effective for plant growth.
- Intervention effect Phosphorus is the most effective of the three fertilizer elements for thiamine activity in plants when applied in optimum quantity.
- Intervention effect Foliar thiamine spray combined with a low concentration sugar solution is more effective than the individual sprays.
- Intervention effect Alkaline chemicals decrease thiamine stability remarkably; mixing foliar thiamine spray with acidic chemicals is desirable.
- Intervention effect Foliar thiamine spray at moderate concentration increases sugar, starch and thiamine contents of crops and raises the C-N ratio of plants.
- Observation Thiamine sprayed on leaves is absorbed by plants in a short time and mostly accumulates in parts of high metabolic activity.
- Observation Most thiamine absorbed by leaves remains in free form, and a part is transformed to the ester form over time.
- Intervention effect Foliar thiamine spray at moderate concentration promotes transpiration, water absorption and photosynthesis of plants and promotes respiration.
- Intervention effect Foliar thiamine spray at moderate concentration makes the respiratory quotient approach 1.0.
- Mechanism Thiamine deficiency in the actively metabolic portion of plants seems to be responsible for the smoothing effects of thiamine through sugar metabolism.
