The correlations between the morphological characters and hetero-zygosity of R.philippinarum from Shanghai, Qingdao, Yantai, Xing-cheng, Dalian and Dandong were studied.
Studies were made on the vegetative propagation coefficient and cormel's biological characters using eighth-excision in different development phase of Lycoris radiate.
(2) all of biological characters, such as cormel's fresh weight, size, height, root length, roughness and root quantities, presented 1% significant difference.
The extract of Sophora japonica L. was processed by inorganic ceramic membrane, and the whole solid, effective ingredinent and flux of mebrane were examined.
The characters of SP1 variation plants at maturity stage also appeared big changes.SP1 variation plants had short growing period, high seed setting rate, loose plant-type and clavated spike-type.
The resistance to float relates to the attributes and conditions of the ground water, the pressure and floatage of water, the change of water level and the sudden supplement of water.
The content of flavanone and lactone in leaf and the leaf output were studied by randomizing block arrangement of 31 gingko female varieties (strain) and 4 staminiferous plant type single clone.
