Effect of different fertilizer application levels on texture of 'Hakuho' peach (Prunus persica Batsch)

Okamoto, G.; Jia Huijuan; Kitamura, A.; Hirano, K.

The changes in biochemical and physical properties of peach Hakuho flesh grown under different levels (160 (H), 80 (M) or 40 (L) ppm) of N application were studied during March 1997 in Japan. Fruits on L treatment were the first to reach a shipping maturity on July 14 followed by M treatment 2 days after and H treatment 6 days after. TSS was highest in fruits of the M and L treatments. Ethylene evolved from harvested fruits was detectable on July 14 and gradually increased in all treatments.
