تاثير مستخلص نباتي الهندباء البري Taraxacum officinale Wigy والخباز Malva parvifloral L. في المركبات الفعالة لنبات الطماطة خارج الجسم الحي in vitro

Research was done in College of Science for Women/ Biology Department/ Plant Tissue Culture Lab. from 2009 to 2010 Results showed that the best plant growth regulator combination for the highest callus quantity production was 1 mg/l Naphthalene acetic acid (NAA) with 2 mg/l Benzyl adenine (BA) so it was fixed in all the preceding experiments. Alcoholic extract for the two plants were added to full Murashigue & Skooge (MS.) and half MS. (modified) with concentration (2,4) mg/l for both as a replacement for vitamins and salts. These extracts showed an effect on the increasing of Ascorbic acid (vit. C) in full MS. medium with 4 mg/l in induced callus of tomato with peak area 68.859 by using Malva parviflora L. and 48.478 by using Taraxacum officinale Wigy and they effect in less degree on Nicotinic acid (vit. B5) with T. officinale Wigy extract effect only at 4 mg/l. with peak area 47.871. They effect on Caffaic acid were nearly abcent.
