Influence of Pruning After Frost Damage to New Shoots in the Early Stage of Growth on the First Crop in 'Saemidori' Tea Field

We urgently studied the influence of pruning shortly after frost damage to new shoots in the early stage of growth on the subsequent first crop in 'Saemidori' tea bush, which had been medium-pruned in the previous year. Shallow-pruning, defined as trimming off about one node of mother stems, made remaining shoots heavier and increased more than 20 percent of yield than no treatment. This result suggested that shallow-pruning enabled early plucking and was expected to diminish the revenue decline caused by frost damage to new shoots early on growth.
