IN VITRO AND FIELD STUDIES ON SAFFRON (Crocus sativus) AND TURMERIC (Curcuma longa)PLANTS
Saffron, Turmeric, NPK, Biofertilizer, NAA, BAP
This study was conducted during the two successive seasons 2009-2010 and 2010-2011, in the Agricultural Experiments and Research Station of the Faculty of Agriculture, Cairo University and tissue culture laboratory of Pomology Dept., National Research Center, Egypt. About the field experiment of saffron corms, one level of biofertilization (1 ml/l), and one level of active dry yeast (6 g/l), in addition to 3 levels of NPK chemical fertlizer ( 50%, 75% and 100%) of the recommended dose were applied. The results showed that, the treatment of 100% of the recommended dose of NPK led to the highest values of vegetative growth i.e. number of sprout and leaves number in the second season only. Also, it increased leave length, number of cormlets, fresh weight of both cormlet and cormlets per plant. In addition it increased nitrogen, and protein percentages both in corms and leaves in the two successive seasons. Application of biofertilization + 75% of the recommended dose of NPK fertilizer led to an increase in leave length, number of cormlets, fresh weight of cormlets, nitrogen percentage of corms, Protein per corm compared with using active dry yeast + 75% of the recommended dose of NPK fertilizers in both two seasons. About the in vitro experiment, parts of the saffron corm explants cultured on MS medium supplemented with BAP and NAA at the rates of 0.0, 2.0, 4.0 and 6.0 mg/L, the concentration (6.0 mg/L NAA +6.0 mg/L BAP) caused significant increase in explant development and greening. Meanwhile, on turmeric, rhizome explants cultured on MSmedium supplemented with BAP and NAA at the rates of 0.0, 1.0, 2.0 and 4.0 mg/L, the high concentration (4.0 mg/L NAA +4.0 mg/L BAP) caused significant increase in callus initiation
