Cím:	Floral analysis as an early plant analitical tool to diagnose nutritional status of fruit trees / Péter Tamás Nagy, József Nyéki, Zoltán Szabó, Zsolt Sándor
Dátum:	2008
Megjegyzések:	A field experiment was conducted in an integrated apple orchard (Malus domestica Borkh.) established on a lowland chernozem soil in East-Hungary, to investigate if flower analysis could be used to diagnose the nutritional status of the trees. In April 2007, during full bloom, flowers and leaves were collected. Leaves were again collected in August, at the standard sampling time from the same trees. The concentrations of nitrogen, phosporous and potassium were measured in flowers and leaves. Correlation analyses were carried out to establish the relations between nutrient contents in same plant part and between nutrient contents in different part plants. The N and P content of leaves was higher than in flowers at full bloom. The opposite was true for K. For all sampling dates, the range of leaf N, P and K contents were wider than that found in flowers. Significant correlation was found between flower P and leaf P and flower K and leaf K at full bloom. Within flowers, the strongest correlation was found between flower N and P content. Significant, positive correlation was also found between leaf K and P at full bloom.
