Changes of SOD,CAT and APX of Brassica napus Infected by Selfing in Total Growth Period;

The Analyses of Inheritance of Aroma Components in Progenies of Selfing and Crossing Combination of Grape;

Number of selfings required to produce a population of recombinant inbred lines;

To overcome incompatibility caused by pre-fertilization barriers in lily breeding,we used two species and three hybrids of lily,to study use of cut-style pollination to overcome incompatibility associated with self-pollination and intraspecific hybridization.

, cross- and self-pollination was made by hand between the cultivars introduced from abroad.

The results showed that pollens in self-pollination germinated normally, and it was the same as that in cross-pollination.

Eliminating local and global self-intersections of offsets based on interval arithmetic and quad trees;

Experimental results show that the morphing sequence produced by this method can avoid shrinkage and self-intersections commendably even when the polygons possess slim belts.

Methods After finding Chinese Bellflower plants with aberrant anther,the natural pollination,artificial pollination and self-crossing experiments were conducted and harvested individually.

Red Glow is a new Doritaenopsis cultivar bred by self-crossing of Doritaenopsis Minho Princess.

The test-tube plantlets of Niitaka pear attained from cultivating self-breed embryo by artificial pollination were selected as material.

In order to provide a theoretical basis for cross breeding and cultivation,this paper conducted a study of the compatibility among 5 Corylus species for their inter-specific hybridization and self-crossing to find out its possible law.
