In this paper the floral ontogeny and the ovary development of rivina humilis l. were observed. the results showed that ( 1 ) the tepal primordia initiated in 2 / 5 spirals. the abaxial one initiated first, then the adaxial one, finally the lateral two initiated nearly simultaneously. the third one initiated on the position near the first tepal, and there is a gap between itself and the second tepal. ( 2 ) the 4 stamineal primordia initiated in one whorl at the same time. ( 3 ) the carpellary primordium initiated from the abaxial side of flower primordium ; the carpellary primordium grew upwards and towards axis after it was formed, therefore an elliptic orifice was formed at the adaxial position of ovary, which was the remainder of the mouth of ovary before the ovary was fused completely. with the ovary maturing, the orifice was narrowed because of the ovary growth, at last fused completely. the gynoecium is composed of a single carpel. ( 4 ) in the series developmental sections of ovary, the ovular primordium was initiated on the adaxial meristem when the mouth of ovary was formed

由此,我們認為植物磷營養狀況調控菌根真菌生長和代謝活性的機制是:當植物處于嚴重缺磷脅迫時,不能合成足夠的碳水化合物供給自身生長的需要,也不能向真菌提供額外的碳水化合物,因而菌根真菌生長受阻,代謝活性較低;當植物中度缺磷時,根皮層細胞質膜的組成和結構不完整,通透性大,碳水化合物通過質膜向外的滲漏量大,菌根真菌因而獲得充足的碳源,保證真菌正常的生長和旺盛的代謝;當植物獲得足夠的磷而使體內磷營養代謝正常時,其細胞質膜組成和結構完整,碳水化合物的滲漏量保持在較低的水平,盡管此時植物合成了足夠的碳水化合物,但菌根真菌仍不能獲得足夠的能量,導致真菌生長受阻和代謝活性降低。The plant expression vector pbin19 - rok219 was constructed, which contains cauliflower mosaic virus ( camv ) 35s promoter and noster. introduction of ibdv vp2 gene under control of camv 35s promoter resulted in the construction of binary expression vector pbr - vp2. then the vp2 gene was in the left and right border regions, which denote the limits of the dna that is integrated into the plant genomic dna via agrobacterium fwme / ac / ms - mediated transformation
