The Character of Anther Development of Impatiens balsamina YANG Shu-juan,CHENG Cheng,SONG Tie-dan,TIAN Hui-qiao 2013, 42(04): 283-287.  DOI: 10.3969/j.issn.1009-7791.2013.04.001 Abstract ( )   PDF (1113KB) ( )   The anther development of the Impatiens balsmina displayed some special characters. In sporogenous cell stage, there are some large sporogenous cells, containing density cytoplasm, locating in the central of anthers. The cells of anther wall contain less cytoplasm which makes both distinguish. In the stage of microspore mother cell, the anther wall consists of 6 layers of cells, but the limit line is not clear between the cells. The tapetal cells begin to display the degeneration at this time. In tetrad stage, the tapetal cells degenerate further as the cells become small. The mature anther wall consists of four layers of cells: one layer of epidermis, two layers of endothecium, and one layer of middle layer. The special characters of tapetal cells of Impatiens balsamina were discussed. References | Related Articles | Metrics

Floral Biology and Pollen Germination of Magnolia championii LIU Kun-liang,WANG Ya-ling,ZHANG Shou-zhou 2013, 42(04): 293-296.  DOI: 10.3969/j.issn.1009-7791.2013.04.003 Abstract ( )   PDF (523KB) ( )   The structure and floral biology were studied in this paper, among which the pollen germination was observed. When all bracts split and fall, stigmas were usually receptive while the flower was still closed. Once the outer tepals were open, the inter-tepals were enclosed so closely that few insects could get inside the flower for pollination. The blooming period were from June to July when it was rainy season in Shenzhen. Few blossoms at the same time could not attract enough pollinators. All of above reason led to the low seed set.

Seed Germination Characteristics of Primula pseudodenticulata SHAO Chang-fen,GUAN Wen-ling,LI Shi-feng,SONG Jie 2013, 42(04): 314-318.  DOI: 10.3969/j.issn.1009-7791.2013.04.008 Abstract ( )   PDF (323KB) ( )   The influence of storage methods, GA3, light, temperature on the germination of Primula pseudodenticulata seeds were experimented. The results showed that the seed germination of P. pseudodenticulata was accelerated by light and the process of dipping in water. The germination could reach 94% on the condition of optimal temperature of 20℃; either higher or lower temperature would affect the seed germination. The low temperature (5 ℃) storage could keep the seeds germination well, but it was better to store the seeds of P. pseudodenticulata less than 4 months and transplant immediately after collection.

Effects of Substrates on Bioleaching of Heavy Metals from Sewage Sludge CHEN Li-xuan,CHEN Fei,CAI Xiao-dong,CHEN Chun 2013, 42(04): 337-341.  DOI: 10.3969/j.issn.1009-7791.2013.04.013 Abstract ( )   PDF (219KB) ( )   Bioleaching of six kinds of heavy metals (Zn, Cu, Pb, Cd, Cr and Ni) from sewage sludge with different substrates was studied, adopting S (concentrations of 5, 10 and 20 g/L), FeSO4·7H2O (concentrations of 10 and 20 g/L) and Na2S2O3 (concentrations of 10 and 20 g/L) as substrate. The results showed that acidification of S was best, because pH could reached about 2 at the forth day, and leaching of Zn、Cu、Pb、Cr and Ni achieved the maximum amount at concentrations of 10 and 20 g/L. Acidification and heavy metals leaching amount of FeSO4·7H2O were not as satisfied as that of S. Dealing with Na2S2O3 at the concentration of 10 g/L showed better results than with FeSO4·7H2O, while the concentration of Na2S2O3 was 20 g/L, filtrate was alkaline, heavy metals were difficult to filter out or even not to filter out.
