Occurrence of Mosaic Disease of Hosta Plane Caused by Hosta virus X

Comparative phylogeographic study of Hosta sieboldiana and Hosta albomarginata (Asparagaceae) in Japan

We analyzed variations in chloroplast DNA (cpDNA) in the widespread herbaceous species Hosta sieboldiana and Hosta albomarginata across large portions of their geographic ranges in the Japanese archipelago. Our objective was to compare the phylogeographic histories and phylogeographic structures of the two congeneric species in the Japanese archipelago. The location of the study is Japanese arc...

New steroidal saponin from Hosta sieboldiana.

An extract of the edible parts of Hosta sieboldiana suppressed the growth of P388 mouse leukemic cells. A new steroidal saponin was isolated from Hosta sieboldiana in this study, and the structure was determined by a spectroscopic analysis to be (25R)-3beta-(alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->3)-[beta-D-glucopyranosyl-(1-->2)]-beta-D-glucopyranosyl-(1-->4)-beta-D-galacto...

Time Course Study of Ancymidol for Micropropagation of Hosta in a Liquid Culture System

The gibberellin biosynthesis inhibitor, ancymidol, was used during micropropagation of Hosta ‘Blue Vision’. Shoot growth and bud division was monitored every 2 weeks over an 8-week period in media containing 1 μM benzyladenine (BA) and various levels of ancymidol (0, 0.1, 0.32, 1 and 3.2 μM). Ancymidol prolonged bud division from 2 to 6 weeks and increased the total number of buds produced. Sho...
