A three-year study over the Bai, Jingpo and Huayaodai communities in yunnan Province reveals that the community development is significantly influenced in various ways by such cultural factors as the concepts of development; concepts and traditions of inter-community relationships, consumption, mar- riage and gender; patterns of decision-making and production, resource and income allocation; as well as the role of information dissemination systems, religion and ritual. Based on the analysis over the interactive relevance between each factor and community development, some strategies and methods for dealing with such a cultural relevance in development projects are recommended.

Let S be an ideal nil-extension of a completely regular semigroup K by a nil semigroup Q with zero. A concept of admissible congruence pairs (δ,ω) of S is introduced, where δ and ω are a congruence on Q and a congruence on K respectively. It is proved that every congruence on S can be uniquely respresented by an admissible congruence pair (δ,ω) of S. Suppose that ρ K denotes the Rees congruence induced by the ideal K of S. Then it is shown that for any congruence σ on S,a mapping Γ:σ|→(σ Q,σ K) is an order-preserving bijection from the set of all congruences on S onto the set of all admissible congruence pairs of S,where σ K is the restriction of σ to K and σ Q=(σ∨ρ K)/ρ K. Moreover,the lattice of congruences of S is also discussed. As a special case,every congruence on completely Archimedean semigroups S is described by an admissible quarterple of S. The following question is asked: Is the lattice of congruences of the completely Archimedean semigroup a semimodular lattice?

作者： XIAO FENGHUI Department of Biotechnology, yunnan Agricultural university, kunming 650201 (China) (Received April 23, 1998 revised June 2, 1998) Department of Biotechnology Yunnan Agricultural University Kunming 650201 China

The effects of boron deficiency on the membrane permeability, the lipid peroxidation of membrane, the activities of the protective enzymes and the accumulation of polyamines in the roots of rape ( Brassica napus L. cv Zhongyou 821) plants were examined using solution culture experiment. Compared to the 20 mmol B m -3 treatment, boron deficient treatment (2 mmol B m -3 ) decreased root dry weight and increased the rate of solute leakage and malondialdehyde (MDA) concentration in the roots of rape. Similar patterns of change were observed in the level of lipid peroxidation (MDA concentration) and the rate of solute leakage under boron deficiency. Results suggested that a significant alteration of membrane composition had occurred under B deficiency. The concentration of putrescine and the ratio of putrescine to spermidine + spermine in the roots of rape increased significantly, and the activities of superoxide dismutase and catalase decreased in the roots of rape during B deficiency. But peroxidase activity in root of B deficient plant was higher than that of control plant.
