This paper summarized the propagation and aquaculture of over ten various major marine fish in Guangdong, including artificial propagtion, Iarviculture, feed, disease, health breed and sustainble develop ment, industrial process , breeding technical condition etc.

The scattered breeding and half wild acclimation of Pantheratigris amoyensis in Meihua Mountain;

Vegetative propagation characters of clonal populations of Hierochloe glabra in Songnen Plain.;

To study the potential invasive characteristics and the successful invasion of alien species Mirabilis jalapa,a series of experiments were carried out to examine the capacities of sexual reproduction and vegetative propagation of M.

An experiment on the taproot cutting of three-year-old seedlings of Carya cathayensis which were treated with different types of hormones of different mass fractions was carried out to accelerate their vegetative propagation and keep their excellent properties.

The sexual and vegetative reproductions of A.

It was widely spread in the alkali-saline meadow in the Songnen plains of China, and there were some biological-ecological and productive characters, such as the tough alkali-saline environment endurance, vigorous vegetative reproduction, long vegetative period after fruit and high value of forage nutrition.

Under natural environmental conditions of Taihu Lake, Elodea Nuttallii and six other species of submerged plant depended mainly on vegetative reproduction to survive and spread their population.

The behavioral budgeting was compared between captive-bred and w.
