* Owing to the initial inconsistency in the first harvest timing for each treatment, the subsequent harvest times differed as well, resulting in the final measurements being dependent on the actual harvest time for each treatment.
** After twenty days post-spawning, primordia emerged in certain treatments, requiring water for inducing regular fruiting, while others had to postpone. Consequently, the timing of water stimulation varied among treatments after the initial twenty days, rendering the collection of pH and moisture data unnecessary.
