In the incubation of soil-added N at two mix rates, 20% Fast + 80% Slow (FS) and 100% Slow (S), a large amount of inorganic N, mainly NH4-N, was released by FS in 4 weeks. Tomato ‘House momotaro’ was grown in 1/2000 a Wagner pots incorporating such N fertilizer and 15N-labeled HV residue (30 g DW/pot, about 200 kg N·ha-1). Plant biomass in tomato grown with HV was larger than that grown without HV. HV-derived N (Ndfhv) was taken up by the tomatoes mainly until 4 weeks after transplant (WAT). The uptake amount of Ndfhv was the same in the pot with HV-FS and HV-S. The rate of N uptake derived from HV to total N uptake in tomato plants (%Ndfhv) was 43% in HV-S, higher than that in HV-FS (34%) in 4 WAT; however, such a difference disappeared after 4 WAT. N uptake by tomato plants continued until 12 WAT. Based on these results, HV acted as a fast-release fertilizer. There was competition in N uptake between chemical fertilizer N and HV-released N in the early stage of tomato cultivation. A large amount of chemical fertilizer tended to suppress the uptake of Ndfhv. N uptake by tomato plant continued until the late stage. These results can be applied to establish a suitable combination of HV and chemical fertilizer for tomato production.","PeriodicalId":17343,"journal":{"name":"Journal of The Japanese Society for Horticultural Science","volume":"83 1","pages":"222-228"},"PeriodicalIF":0.0,"publicationDate":"2014-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69158212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unpleasant odors from cut flowers have become a problem in this region. We investigated volatiles emitted from cut flowers of ‘Hatsubeni’ and ‘Haresugata’, two major Japanese ornamental cabbage cultivars in Europe, by gas chromatography-mass spectrometry (GC-MS). Dimethyl disulfide was identified as the major odor-active component emerging from plants as well as from vase water. Vase water was a major source of unpleasant scents, and odor development was prevented by changing the water frequently. We tested the effects of potential suppressors of dimethyl disulfide emission from cut flowers applied to vase water. Cyprodinil, an inhibitor of the synthesis of dimethyl disulfide from methionine, and aminooxyacetic acid, an inhibitor of enzy-matic reactions involved in dimethyl disulfide biosynthesis, did not show any effects. In contrast, isothiazolinonic germicide, a cut-flower preservative, inhibited the rot of cut ends of flower stems and reduced dimethyl disulfide emission from cut flowers by 30–40%. In addition, this germicide significantly inhibited emissions from vase water. Isothiazolinonic germicide is a promising candidate inhibitor of unpleasant scents from cut flowers of ornamental cabbage.","PeriodicalId":17343,"journal":{"name":"Journal of The Japanese Society for Horticultural Science","volume":"83 1","pages":"252-258"},"PeriodicalIF":0.0,"publicationDate":"2014-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2503/JJSHS1.CH-093","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69158347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the phylogenetic relationship of H. macrophylla (Thunb.) Ser. f. normalis (E.H.Wilson) H.Hara and H. serrata (Thunb.) Ser. was evaluated by using RAPD markers and sequences of the plastid genes rbcL and matK. The materials were collected from their wild populations throughout Japan. Both RAPD analysis and chloroplast DNA analysis indicated that the genetic diversity of H. serrata var. serrata was higher than that of H. macrophylla f. normalis or that of H. serrata (Thunb.) Ser. var. yesoensis (Koidz.) H.Ohba. These analyses revealed that H. serrata var. serrata of Japan was separated into two groups; i.e., eastern serrata group and western serrata group. The western serrata group was divided into two or three subgroups by single base substitutions in the matK or rbcL fragment sequences. The results of chloroplast DNA analysis indicated that H. serrata of Shikoku, which was one of the western serrata subgroups, was evolutionarily differentiated from other western serrata subgroups. MatK and rbcL sequences of the eastern serrata group were identical to those of H. macrophylla f. normalis and H. serrata var. yesoensis. The matK sequences of the eastern serrata group, H. macrophylla f. normalis and H. serrata var. yesoensis, contained a duplication of 6 bp (GGTTAT), which was not found in the western serrata group or other Hydrangea species. Analysis of the matK and rbcL sequences revealed that H. serrata var. serrata is paraphyletic and that the eastern serrata group, H. macrophylla f. normalis and H. serrata var. yesoensis, form a monophyletic group. The present study provided useful information for breeding hydrangea cultivars and for the taxonomic treatment of H. macrophylla and H. serrata including the varieties.","PeriodicalId":17343,"journal":{"name":"Journal of The Japanese Society for Horticultural Science","volume":"83 1","pages":"163-171"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2503/JJSHS1.CH-092","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69158789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To offer satsuma mandarin growers information for making replanting decisions, we estimated future changes in locations suitable for the cultivation of tankan (Citrus tankan Hayata), the leading subtropical citrus in Japan. The results of fruit-freezing experiments suggested that the threshold air temperature for the cold tolerance of tankan fruit is about -2°C. The locations suitable for tankan were simulated on the basis of future annual mean air temperatures evaluated by the MIROC3.2-HiRes climate model under the SRES-A1B GHG emission scenario and future annual minimum air temperatures calculated from future daily minimum temperatures evaluated by this climate model and the current air temperature variability. The results of the simulation showed that most of the Pacific coastal area from the Kanto Plain and to the west will become suitable for tankan cultivation during 2031–2050, and that coastal areas of the current satsuma mandarin-producing regions in Japan should be suitable for tankan production by 2050. The inland area of southern Kyushu Island, despite its proximity to current tankan-producing regions, is predicted to experience temperatures causing a high frequency of cold injury to tankan fruits even during 2051–2070. Therefore, if satsuma mandarin production becomes difficult on account of increased global warming, tankan could be produced as a substitute in coastal areas of the current satsuma mandarin-producing regions. However, we predict that it will be difficult to produce tankan in inland areas of the current satsuma mandarin-producing regions.","PeriodicalId":17343,"journal":{"name":"Journal of The Japanese Society for Horticultural Science","volume":"83 1","pages":"117-121"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69158363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, shoot formation percentage was lower under dark conditions (8.0%) than under low light (66.0%) and high light conditions (68.2%) and few PLBs developed shoots during culture under dark conditions. The Secondary ePLBs obtained after culturing under dark conditions were approximately twice as long as nPLBs. After acclimation under low light conditions for 2 weeks, the ePLBs were transferred to high light conditions after making a partial incision in their apical parts. Under high light conditions, a large number of secondary PLBs were obtained from ePLBs, 6 times as many as from nPLBs treated with the same partial incisions. The findings of this study showed that culturing PLBs in dark conditions suppresses shoot formation that might interfere with PLB proliferation, and that a large number of secondary PLBs could be obtained from these ePLBs compared with nPLBs after exposure to high light intensity.","PeriodicalId":17343,"journal":{"name":"Journal of The Japanese Society for Horticultural Science","volume":"83 1","pages":"149-155"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2503/JJSHS1.CH-083","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69158020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tiny reddish-brown blotches appear on the surface of berries and considerably decrease the grape’s market value. Although the mechanisms and factors for browning are unknown, we hypothesized the involvement of polyphenol compounds and their oxidation reactions. In this study, the gene expressions of polyphenol oxidase (PPO), stilbene synthase (STS), and chalcone synthase (CHS), which are key enzymatic genes related to the metabolic pathway for polyphenols, were analyzed during berry maturation to examine the molecular basis for browning. Skin browning occurred on several berries in a bunch of ‘Shine Muscat’ from 80 days after full bloom (DAFB), after which the number of berries with skin browning increased, and the browned area spread on the berry surfaces with maturation. Increases in the expression of VvPPO2, VvSTS type B, and VvCHS1 were associated with skin browning, and the trans-resveratrol content also increased in the browning skin, suggesting that biosynthesis and metabolic pathways for phenolic compounds were activated at the time of browning. In terms of VvPPO genes, specific up-regulation of VvPPO2 expression was observed compared with the VvPPO1 gene. The promoter sequence of VvPPO2 contains more Myb binding motifs and W-box motifs than does VvPPO1. The specific up-regulation of VvPPO2 gene expression will play a crucial role in understanding and managing the skin-browning mechanism in the grape berries of ‘Shine Muscat’.","PeriodicalId":17343,"journal":{"name":"Journal of The Japanese Society for Horticultural Science","volume":"83 1","pages":"122-132"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2503/JJSHS1.CH-095","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69158905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Immature cotyledons of different cultivars and different developmental stages were subjected to sonication treatment of durations ranging from 10 sec to 2 min. When early-stage immature cotyledons of ‘Nanko’ were subjected to sonication treatment, the transient GFP expression frequency after co-cultivation was nearly 100% and GFP fluorescence was distributed over almost the entire cotyledon surface. In contrast, when the inoculation was carried out according to the standard dipping method, transient GFP expression frequency was less than 10% and GFP fluorescence was observed only in spots. The highest frequency of somatic embryogenesis (SEG) with GFP expression was obtained from 40 sec sonication treatment of May 14 ‘Nanko’ immature cotyledons.

Twenty-three genes were identified and grouped into 10 clades, which were characterized by conserved specific motifs. Phylogenetic analysis indicated the diversification of AG/PLE, AP3/DEF, PI/GLO, and SEP clades and the occurrence of recent gene duplication events. The floral organ-specific expression patterns were partly diversified within the gene members of AP3/DEF and SEP clades, while they were conserved in AG/PLE and PI/GLO clades.

In addition to these determinant genes, non-S factors, called modifier genes, are required for the GSI reaction. Here, we conducted large-scale transcriptome analysis of unpollinated, self-pollinated, and cross-pollinated pistils of Japanese apricot ( Prunus mume Sieb. et Zucc. cv.

We obtained 40,061 unigenes from 77,521,310 reads from pollinated and unpollinated pistils and pollen grains. Among these unigenes, 29,985 and 27,898 unigene sequences showed at least one hit against the NCBI nr and TAIR10 protein databases, respective - ly, in BLASTX searches using an E-value cutoff of 1e-6.
