Vegetative Growth and Fruit Development of Nectarine Under Protected Cultivation Conditions
Abstract：3 nectarine and 1 peach varieties were used for observing the growth and development process of shoot and fruitunder protected cultivation. Results showed that the biomass of fruit, total new shoot length and total leaf area per tree wasincreased by 66.2%, 100.0% and 87.1% respectively in the greenhouse than those in open field, but the special leaf weight(SLW) and ratio between root and canopy were decreased significantly. The competition in carbohydrates between shoot andfruit growth was aggravated by the protected cultivation conditions. Under protected cultivation conditions the fruit growth wasdisplayed in the form of prolonging stage Ⅰ and stage Ⅲ, shortening stage Ⅱ, the fruit development period (FDP) wasprolonged by 10～15 days. The average length (days) of each stage of FDP was significantly correlated with the Ta of night(r=-0.9150*). The fruits inside the greenhouse were bigger than those outside the greenhouse because the division of sarco-carp cells was promoted by the lower night temperature during stage Ⅰ inside the greenhouse.
