• The genetic relationship of leaf-used Ginkgo biloba L. germplasms were evaluated by flavonoids and ginkgolides contents and AFLP markers. The results showed that rich genetic diversity existed in both flavonoids and ginkgolides contents and AFLP markers. The average content of leaf extracts（Ga，Gb，Gc，Gj，Bb，Te，GF）in 68 leaf-used G. biloba L. germplasms are 0.0371%，0.0185%，0.0280%，0.0133%，0.0243%，0.1216% and 1.7103% respectively. Among the 1 408 bands obtained from 8 selective primer pairs，99.28% of them were polymorphic. Nei’s genetic diversity was 0.1939，and Shannon’s index was 0.3142. The molecular genetic similarity coefficients range from 0.2924 to 0.7413，with an average of 0.4888. The results of hierarchical cluster analysis based the flavonoids and ginkgolides contents of different populations and UPGMA exhibited a good consistency. By the hybrid method of flavonoids and ginkgolides contents and AFLP markers analysis，screen out the distinctive G. biloba germplasms of high-flavonoids and ginkgolides，would be valuable for germplasm management and utilization of leaf-used G. biloba L. germplasm.

• The effects of cold storage temperature（–1，0，1.5 and 5 ℃）on superficial scald，core browning and fruit quality of‘Dangshan Suli’pears（shelf-life at 20 ℃）harvested from Taigu and Linyi districts in Shanxi Province were investigated. The results showed that the superficial scald was mainly detected during shelf-life at 20 ℃ after 200 days cold storage，and the lower the storage temperature，the worse the superficial scald disease. The core browning index of fruit stored at–1 ℃ and 5 ℃ was obviously higher than that at 0 ℃ and 1.5 ℃. The fruit firmness and soluble solids content（SSC）kept well when stored at 0 ℃ and 1.5 ℃，as well as the taste and flavor. For the fruit stored at 5 ℃，the fruit firmness was the lowest and the decay rate was the highest. While for that stored at–1 ℃，the fruit firmness and SSC decreased，and the fruit flavor became worse，although the decay rate declined. The effects of low temperature on fruit quality of ‘Dangshan Suli’ pears harvested from Taigu and Linyi wereconsistent. The research indicated that the optimum temperature was 0–1.5 ℃ for long time storage and 1.5–5 ℃ for short time storage（120 days or less），respectively.

• Abstract ( 573 ) HTML ( 870 ) PDF (435KB) ( 870 ) 　　　
• 25S rDNA-FISH was applied to analyze metaphase chromosome components and meiotic chromosome behavior of Chinese cabbage–head cabbage allotriploid（ACC），and pollen character and the fecundity of the allotriploid was studied. In the 25S rDNA-FISH analysis for metaphase chromosomes，Chinese cabbage–head cabbage allotriploid was verified to have 28 chromosomes and contains 9 locis of 25S rDNA，among them 4 locis mapping on chromosome 4 and 7 of head cabbage，and the other 5 locis mapping on chromosome 1–5 of Chinese cabbage. There was different degree of homology between A chromosomes and C chromosomes. At meiotic diakinesis，the chromosomes often form different association patterns，such as univalent，bivalent，and trivalent，etc. There were dissociated chromosomes at metaphaseⅠand Ⅱ，chromosome unequally segregating，lagging and losing at anaphaseⅠand anaphaseⅡ，and micronuclei forming at telophaseⅡ. These results led to that pollen regularity and pollen viability of allotriploid was much lower than that of its diploid parents. Whether this allotriploid was selfing or backcross with head cabbage，the seed setting rate was very low，only 0.01%.

• JIN Zhi-Yong, WANG Shuo-Shuo, LIU Na, GONG Biao, LIU Shi-Qi, SHI Qing-Hua
• Acta Horticulturae Sinica. 2014, 41(12): 2411-2418.
• Abstract ( 485 ) HTML ( 1065 ) PDF (499KB) ( 1065 ) 　　　
• ‘Ershuizao’garlic was used as experimental material to investigate the effects of different photoperiod treatment on the enlargement and nutritional quality of garlic bulb. The results indicated that the 14 h（7 h natural light + 7 h artificial light）uninterrupted illumination was necessary for garlic bulbing enlargement. However，under 7 h natural light，all supplements of light from 1 h to 7 h to break darkness at night could increase the bulbing enlargement more quickly than continuous 14 h illumination treatment. The difference of bulb weights among treatments of darkness break（1 - 7 h）was not significant. With the extension of light supplying at night（1 - 7 h），contents of leaf pigment，allicin，soluble sugars，vitamin C，soluble proteins and free amino acids of bulb were increased first and then decreased，and the treatment of 5 h darkness break showed the highest levels of pigment，vitamin C，soluble proteins and freeamino acids content in the bulb，which is about 30.0%，7.7%，36.2% and 25.3% higher than 14 h uninterrupted illumination，respectively. Furthermore，both the content of total phenol and the free radical scavenging rate also showed the highest level in the treatment of 5 h darkness break. If the main purpose of protected garlic production was to get the yield，1 h darkness break treatment was enough，if both yield and quality were considered，5 h darkness break was the proper treatment.

• Acta Horticulturae Sinica. 2014, 41(12): 2419-2426.
• Abstract ( 554 ) HTML ( 1285 ) PDF (2026KB) ( 1285 ) 　　　
• The effects of silicon on ultrastructure and active oxygen metabolism in root mitochondria were studied with a tomato（Solanum lycopersicum）cultivar‘Jinpeng 1’in cultured hydroponics under PEG-6000 simulated drought. The results showed that with the extension of drought stress，the root activity of tomato plants gradually decreased. Malondialdehyde（MDA）content，mitochondrial superoxide anion（）productivity rate and hydrogen peroxide（H2O2）content gradually increased，but the activities of superoxide dismutase（SOD），peroxidase（POD）and catalase（CAT）rapidly increased in the early stage of drought stress，and then rapidly decreased after peak. The application of silicon significantly effected the change of the related indicators caused by drought stress. After 12 days of drought stress，the content ofMDA，and H2O2 in roots of tomato with silicon were lower than that of tomato without silicon by 25.14%，8.34%，20.25%，respectively. But root activity，SOD activity，POD activity and CAT activity were higher by 139.62%，243.19%，65.53%，125.55%，respectively. In addition，the application of silicon not only reduced plasmolysis of tomato root cells，but also relieved the damage of mitochondria，nuclei and biofilms.

• Gene expression microarray of petunia was applied to select cold responsive gene，from which a B-box-type zinc-finger protein gene PhBBX8 was discovered. The full length of the coding region of PhBBX8 amplified by RT-PCR was 1 242 bp，and the product of PhBBX8 gene was predicted to consist of 413 amino acid residuals containing two B-box domains at the N-terminal and one CCT domain at the C-terminal. The phylogenetic tree analyses showed that PhBBX8 was clustered in the same branch with AtBBX8 in Arabidopsis. By semi-quantitative RT-PCR，PhBBX8 was found to express differentially in all the tissues detected，including root，stem，leaf and flower. Stress induced expression analysis by real-time quantitative PCR showed that the expression of PhBBX8 could be induced not only by cold，but also by drought，ABA，MeJA，salt and hypertonic stresses in different degrees，suggesting PhBBX8 gene was associated with the responses of cold and other abiotic stresses.

• LilyABC1，a gene encoding protein kinase，was cloned and its expression patterns in Lilium regale Wilson under abiotic stresses were dissected for the purpose of providing a candidate gene for lily breeding for resistance to various abiotic stresses. Plant material of wild Lilium regale Wilson was used to clone the full-length cDNA sequence of lilyABC1 using RACE technology in combination with cDNA library. A number of appropriate bioinformatics softwares were used to assay the structure of cDNA sequence and the function of deduced lilyABC1. The real-time quantitative PCR（qRT-PCR）method was applied to determine lilyABC1 expression patterns in specific tissues under different abiotic stresses including PEG-6000，NaCl，low temperature，high temperature and darkness. The results showed that thelilyABC1 cDNA was 2 333 bp with a 2 007 bp open readings frame in full-length. The sequence of the lilyABC1 consists of 668 amino acids with a molecular mass of 74.84 kD. The pI value of this protein is 5.46 and containing STYKc conserved domain. The expression levels of lilyABC1 were ranked as leaf > flower bud > bulbs；There was no obvious expression difference among different development stages of the flower buds. The expression of LilyABC1 was up-regulated by NaCl，low temperature，high temperature and darkness，but it was not sensitive to the PEG-6000. Therefore，lilyABC1 might have contributed to its resistance to abiotic stresses such as NaCl，low temperature，high temperature，dark and drought.

• An experiment was conducted by using TEM to study the ultrastructural changes in zygote and proembryo of Plantago major L. The results were as follows：Embryonic development of Plantago major L. was epilobium type. With the development of zygote，cell wall gradually formed，the volume increased，the polarity inhanced，and starch began to store in plastids. The zygote divided into basal cells and apical cells in first cross division after the primary endosperm nucleus division. Basal cell formed a single line cells after several times division，which developed into suspensor. Apical cell formed embryoid body after several times cell division. There were very large cell nucleus with obvious nucleolus and many variety types of organelles in embryoid body cells. These organelles of embryoid body cells had strong meristematic ability and high metabolic ability. In the early stage of small ball embryo，nutrients were from the storage of zygote，absorption and transport by suspensor. In the early stage to middle stage of small ball embryo，the suspensor tissue developed rapidly by absorping nutrients from integument andtransporting them to embryoid body. In the late period of big ball embryo，suspensor disintegrated and embryonic body peripheral cells absorbed the degradation products of endosperm cells as the nutrients for embryonic development.

• Degenerate primers were designed according to the known conserved regions of Ornithine- δ-aminotransferase gene（δ-OAT），and the complete cDNA sequence of δ-OAT was firstly cloned from Camellia sinensis using RT-PCR and RACE technologies. The cDNA was termed Csδ-OAT（GenBank accession KJ641844）and its full-length was 1 865 bp encoding a protein of 473 amino acids. The molecular weight of Csδ-OAT was 52.3 kD and theoretical isoelectric point was 7.19. The BLAST results showed that the functional domain of Csδ-OAT is highly conserved with a typical PLP binding site. Phylogenetic analysis of plant δ-OAT reveals that the evolution of Csδ-OAT corresponds with traditional biological classification. QRT-PCR analysis results showed that the expression of Csδ-OAT has obvious tissue specificity，and it was higher in flower，followed by leaves，but lower in other tissues. Moreover，we found that the expression of Csδ-OAT is induced by different abiotic stresses，including low- temperature，high salinity，ABA，drought and oxidative stresses，implying that Csδ-OAT is involved in responding to abiotic stress in plants.

• This experiment was conducted to explore the effect of low molecular weight organic acids on the biomass and physiological characteristics of Malus hupehensis Rehd. seedlings under continuous cropping. Seedlings were grown in pots were treated with oxalic acid，tartaric acid，citric acid，malic acid and the mixture of the these four organic acids. The effects of organic acids on the photosynthetic parameters，the activities of antioxidant enzymes and root system of M. hupehensis Rehd. seedlings were investigated. Compared with controls，oxalic acid could significantly promote dry and fresh weight of plant by 24.12%，35.72%，respectively. The net photosynthesis rate，stomatal conductance were significantly increased by 32.27%，76.58%，respectively. At the same time，oxalic acid could also significantly improve the activities of POD，and CAT. However tartaric acid remarkably inhibited the stomatal conductance by 40.22%. The activities of SOD and POD were also inhibited，respectively. In conclusion，the oxalic acid could promote the growth of M. hupehensis Rehd. seedlings and alleviatethe effect of replant disease on seedlings，while the tartaric acid aggravated the effect of replant obstacle on seedlings. The citric acid and malic acid showed no significant influence on replant obstacle for seedlings.
