During ripening of strawberry fruit, the top part of fruit first turns red and then the fruit gradually becomes full red. The top part of strawberry fruit is sweeter than the middle and bottom parts, so we speculate that the distribution of P in fully ripened strawberry fruits is not homogeneous. To verify this hypothesis, we measured SSC and P content in different parts of fruits (Fig. 3a). It clearly showed that both SSC and P content increased from bottom to top in fully ripened strawberry fruits of both ‘Sachinoka’ and ‘Sweet Char-lie’ (Fig. 3b and c). The ratios of SSC between top and bottom parts were 1.7 (12.4◦Brix/7.2◦Brix) and 1.5 (9.7◦Brix/6.5◦Brix) for ‘Sachi-noka” and ‘Sweet Charlie’, while the ratios of P content between to pand bottom parts were 1.7 (16.6 mol · g−1/9.8 mol · g−1) and 2.4(16.3 mol g−1/6.9 mol g−1) for ‘Sachinoka” and ‘Sweet Charlie’,respectively. For different parts of strawberry fruits, there also was a significant positive correlation between SSC and P content with the correlation coefficient r = 0.87 (p = 0.01).
