Abstract:

This study investigated the effect of environmental factors on fruit growth in two cultivated honey peach varieties,Hujingmilu and Fenghuayulu,in Fenghua. Based on monitoring of orchard environment and fruit morphology,Pearson correlation analysis was employed to establish quantitative relationships between absolute fruit growth and accumulation values of temperature,as well as relative fruit growth and accumulation values of humidity. The results indicated that the longitudinal,transverse,and lateral diameters of fruits in both varieties follow an S-shaped growth curve. The accumulation values of air temperature and soil temperature showed a significant(p<0.05)or extremely significant(p<0.01)positive correlation with the longitudinal,transverse,and lateral diameters of fruits,with soil temperature generally exhibiting higher correlation coefficients than air temperature. The effect of soil humidity displayed significant varietal heterogeneity,accumulation values of soil humidity after 20 days of hard core period was significantly or extremely significantly positively correlated with the relative values of longitudinal,transverse,and lateral diameters of Hujingmilu fruits,while Fenghuayulu fruits were insensitive to changes in humidity over the same period,reflecting differences in water use strategies and swelling rhythms between Hujingmilu and Fenghuayulu. This research provides a theoretical basis for differentiated cultivation and precise water regulation of honey peach varieties.
