ACCLIMATIZATION AND DEVELOPMENT IN FIELD OF GINGER HAPPENED OF MICROPROPAGATED AND CONVENTIONAL TYPE

Abstract

Ginger (Zingiber officinale R.), has been highly used for its therapeutic properties.  The limiting factor for this growing is the presence of diseases caused by fungi from the soil that is detected by micropropagation, producing high quality plantlets free from pathogenes. The objective was to evaluate the development of the micro propagated ginger plantlets after 30 days of acclimatation in three different substrates: T1- Sand + Plantmax^® (1: 1); T2 – Carbonized rice shell + Plantmax^® (1: 1), and T3 – Sand + Plantmax^® + Carbonized rice shell (1: 1: 1), the development at field and to obtain informations about total soluble sugars levels in different stages of the plant. The substrates affected in similar ways form the development of the ginger in the acclimatation. The development in field of the micro propagated plantlets was different comparing with the conventional propagation. On the 30^th day the plantlets that had rhizomes showed greater values in evaluated parameters: height, number of leaves and proliferations and those, Nevertheless, on the 60^th day of cultivation the micro propagated plantlets displayed a greater number of proliferations, results that showed a significant statistical difference. In the evaluation of the amount of total soluble sugars, carried through in rhizomes of the plants proceeding from the conventional propagation, superior values were observed to those found in rhizomes of plants with origin in the micropropagation, 1621,29±15,32 e 164,91±2,4 mg Eq Glu g^-1 MF, respectively, what explains the superior initial growth , to compare with micro propagated plantlets.
