Abstract

Abstract Changes in the accumulation patterns of mineral nutrients at different development stages of fruit reflect the requirements of citrus trees for different nutrients, and this information provides an essential reference for rational fertilization. In this study, changes in the contents of 11 nutrients in the whole fruit, fruit pulp, and peel were studied during the whole developmental period of the fruit of ‘Seike’ and ‘Newhall’ navel oranges. We found that the two navel orange cultivars showed very similar changes in nutrients. Specifically, the N, P, Mg, S, Mn, and Zn contents were high in the young fruit stage (April), the K and Fe contents were high in the fruit expansion stage (July and August), and the Ca content was high in the fruit maturation stage (October). As the fruit developed, the N, P, Mg, S, Zn, and B contents decreased to the lowest levels at fruit maturity in November. In addition, the contents of N, P, K, Fe, Zn, and Cu were ranked as fruit pulp > whole fruit > peel, while Ca, Mn, and B contents were ranked as fruit peel > whole fruit > fruit pulp. N, P, K, and Mg accumulated in the fruit in June and July, in contrast to the June to September period for the micro-elements. During these accumulation periods, it is recommended that suitable fertilizers be applied in a timely manner.

Highlights

Materials and MethodsMineral nutrients determine the growth, development, yield, and quality of fruit trees (ALVA et al, 2006; RAZZAQ et al, 2013; BRUNETTO et al, 2015; ZHOU et al, 2018)
Many studies have reported the seasonal changes in mineral nutrients of citrus leaves (ZHOU et al, 2004; XIAO et al, 2007; SHENG et al, 2009; MIRSOLEIMANI et al, 2014)
The application amount of fertilizer can be calculated according to the nutrition concentration of fruit and the target yield (ZEKRI et al, 2005; OBREZA; MORGAN, 2008)

Summary

Introduction

Materials and MethodsMineral nutrients determine the growth, development, yield, and quality of fruit trees (ALVA et al, 2006; RAZZAQ et al, 2013; BRUNETTO et al, 2015; ZHOU et al, 2018). Previous studies have been conducted to analyze the total contents of nutrients in fruit and the total requirements of citrus trees with respect to mineral nutrition (OBREZA; MORGAN, 2008; ROCCUZZO et al, 2012). The N, P, and Mg contents in the fruit pulp and peel of both ‘Seike’ and ‘Newhall’ continuously decreased from July 26 to November 30, similar to those in the whole fruit.
