Abstract

In protected mother-fern cultivation of asparagus, spear yield during the spring is influenced by the accumulation of photosynthetic products in storage roots from the previous autumn.
However, high temperatures during the summer decrease spear yield because the number of sprouting spears decreases and the number of abnormal spears increases.
In this study, the effects of air and root zone temperature conditions on the partitioning of photosynthates in asparagus were evaluated.
The air temperature (AT) conditions were 30, 20, and 15°C, and root zone temperatures were AT+5°C, similar to AT, and AT−5°C at each air temperature.
Whole aboveground parts of 1-year-old potted ‘Vegalim’ plants (AT 30°C) and “UC157” plants (AT 20°C and 15°C) were fed ¹³CO₂ under the combination of temperatures mentioned above.
We evaluated the distribution of ¹³C photosynthates in the plants three days after ¹³CO₂ feeding.
If the air temperature was 30°C, the proportion of ¹³C distribution to the storage root and spear tended to be higher when the root zone temperature was lower than the air temperature.
If the air temperature was 20°C, little difference was detected in the proportion of ¹³C distribution among the root zone temperatures.
If the air temperature was 15°C, the proportion of ¹³C distribution to the storage root tended to be higher when the root zone temperature was higher than the air temperature.
These results suggest that control of the root zone temperature to be lower than the air temperature would be effective in increasing the spear yield during summer, and control of the root zone temperature to be higher than the air temperature in autumn would be effective in increasing the spear yield in the following spring by increasing the distribution of photosynthates to the storage roots.
