One third or half of lateral roots of 3-year-old potted ‘Delaware'grapevines were removed after estimating their total accumulated carbon dry weights in late autumn, and the early growth of new shoots was investigated.
In the next spring, the time of budbreak and each leaf expanding, the curve of growth rate in length and the water content of new shoot had not any affection by root removal. When the 10th leaf began to expand, the shoot length, the total leaf area and the total carbon dry weight of per shoot appeared in direct proportion to the amount of total accumulated carbon, while the size of inflorescence did not differ significantly with root removal. But the carbon content of inflorescence was less marked in the half root removal than in the one third or the no root removal.
The results are considered to indicate that the root removal in autumn is a good method for investigating the relationship between the amount of accumulated carbohydrate and the early growth of new shoots.
