Influence of Pseudomonas fluorescens and Ferrous Sulphate on Iron Status of leaves and Fruit Quality of Low Chill Peach cv. Flordaprince

摘要

An experiment was conducted to find out the effect of Pseudomonas fluorescens PBAP-27 along with foliar spray ferrous sulphate on low-chill peach plants suffering from iron deficiency. Leaf iron status viz. active iron, total iron and ferric iron andphysico-chemical parameters of fruits viz. weight, volume, ascorbic acid, reducing sugar, non-reducing sugar and total sugar were recorded. The results obtained from the investigation showed significant increase in leaf iron status, fruit weight, fruit volume and ascorbic acid content in fruit with the inoculation of Pseudomonas fluorescens PBAP-27 as well as foliar spray of ferrous sulphate. The inoculation strain PBAP-27 of Pseudomonas fluorescens along with foliar spray of ferrous sulphate were notedas significant for increasing leaf iron status and ascorbic acid. Thus, inoculation of Pseudomonas fluorescens PBAP-27 and foliar spray of ferrous sulphate, can be used as strategy for iron fertilization for improving leaves iron status and fruit quality parameters namely , fruit weight, fruit volume and ascorbic acid in low chill peach.
