Standardization of propagation and agro techniques in Ginkgo biloba L. - A medicinally important plant

Gopichand, R. L. Meena

Due to the high medicinal value and high demand of its herbal products globally, it has been exploited indiscriminately and facing high risk of extinction. An efficient and sustainable protocol has been developed for its propagation by semi hard stem cuttings and by seeds also. Some growth hormones have been used in different concentrations. The highest sprouting (%) was recorded in the Catchin acid at 10 mg/l (96.67%) and lowest in Tanic acid 2.5 mg/l (24.0%). The statistically significant rooting (%) and root length/plant in 2nd year was recorded in IBA 250 mg/l (85.33%). In IBA + Phloroglucinol, 250+10 mg/l, and Salicyclic acid 25 mg/l, (7.33) and average root length/plant were recorded in IBA 250 mg/l, (13.67cm). In NAA 250 mg/l (14.67cm). The statistically significant seed germination (%) in IBA 250 mg/l (85.74%) and NAA in 500 mg/l (84.73%) was also comparable. (FYM doses viz, 15, 30, 45 & 60 t/ha with control) were recorded in monthly interval from 2005 to 2013 statistically analyzed on a yearly basis. The purpose of FYM x Spacing trial was to study the potential of leaf production for commercial use. In 2009 to 2013, FYM 30 t/ha produced highest quantity of leaves.
