Three inoculum levels of AMF namely control, 1:1 and 1:2 (v/v) ratio of inoculum to propagation substrate, respectively and two levels of cutting types designated as middle and basal cutting positions were used. Rooting parameters in terms of rooting percentage, root number, root length and root dry weight were evaluated. Analysis of variance revealed that the effect of AMF inoculation was significant (p<0.001) only for percent rooting and root dry weight among the rooting parameters evaluated. The effect of cutting type and the interactive effect of inoculation and cutting type were insignificant for all studied rooting parameters. Comparisons of means by Duncan’s Multiple Range Test (DMRT) for the different treatments revealed that the quantity of inoculum significantly (p<0.05) influenced high performance in all rooting parameters evaluated. The highest percentages in rooting was (67.28%) for the cuttings from basal position. The study has revealed a strong AMF influence on rooting ability of auxin treated stem cuttings in D. melanoxylon. It was concluded that for vegetative propagation, AMF inoculum should be used for auxin treated cuttings to produce high quality planting stock material for the afforestation and conservation programme for D. melanoxylon.","PeriodicalId":275718,"journal":{"name":"Research Journal of Botany","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125816181","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}

Juvenile stem cuttings were collected from wild populations in Brunei Darussalam. The cuttings with or without leaves were treated with Indole Butyric Acid (IBA), Naphthaleneacetic acid (NAA), or Indole Acetic Acid (IAA) at 0, 0.01, 0.05, 0.10, or 0.20% (w/v) using a quick-dip method, planted in rooting media and kept in a misted greenhouse. The survival and rooting percentages, number and length of new roots produced, number and area of leaves and Relative Growth Rate (RGR) based on stem length and stem diameter were assessed at a 4-week interval for 24 weeks. The leafless cuttings and leafy cuttings treated with distilled water after week 4 and 16, respectively, did not survive. All of the leafy stem cuttings treated with 0.10 and 0.20% NAA and 0.20% IAA survived for 24 weeks. Leafy stem cuttings treated with 0.10 and 0.20% NAA and not ABA had formed significantly more and longer roots than cuttings in the other treatments at week 8. Leafy stem cuttings treated with 0.10% IAA had more new leaves and greater leaf area, than cuttings in the other treatments at week 8. There were no significant differences in the RGR of leafy stem cuttings among the different treatments at week 8. This study demonstrates that treatments with 0.10-0.20% NAA and 0.10% IAA and not IBA resulted in the development roots and shoots from leafy stem cuttings and can be used for the mass production of D. suffruticosa plantlets, which will prevent the over exploitation of wild stocks.","PeriodicalId":275718,"journal":{"name":"Research Journal of Botany","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125169776","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}

Vegetation is a major element of these systems as roots bind sand and thereby, stabilize dunes and shoots promote dune growth. The dunes of the Mid-Atlantic U.S. are stabilized by two alpha species that compete for space and resources-native American Beachgrass (Ammophila breviligulata) and invasive Asiatic Sand Sedge (Carex kobomugi). Despite the importance of these species, today many of the biological and physiological factors underpinning their competition remain poorly understood. Therefore, we conducted a 7 week greenhouse competition study with transplanted A. breviligulata and C. kobomugi ramets. We manipulated substrate amount and salt spray as treatments in a factorial-designed greenhouse experiment. Despite ample acclimation prior to testing and appropriate abiotic conditions throughout, we had very low survivorship for both species. This was especially true for C. kobomugi, which may be largely intolerant of wet substrate conditions. We performed microscopy to begin to understand the morphological and physiological differences that could have drive differences in our survival rates. Our results provide information useful for the design and uses of future attempts at conducting coastal vegetation transplant studies.","PeriodicalId":275718,"journal":{"name":"Research Journal of Botany","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129961971","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}

Alkaloids, fats, oils, inulin, protein and starch profiles of the taxa studied \u0000generated three groups using Principal Component Analysis (PCA) and four clusters using Cluster \u0000Analysis (CA). The resultant groups and clusters showed the species did not segregate across \u0000traditional lines but aligned with taxa outside genus and family borders. The species Chenopodium \u0000botrys and Chenopodium polyspermum were most divergent, constituting a separate group and \u0000clusters. The majority of the species segregated as a primary group/cluster, showing close affinities \u0000between members of both families; hence, the Amaranthaceae-Chenopodiaceae group can be \u0000regarded as a mono-paraphyletic group. Alkaloids were recorded only in Chenopodiaceae taxa and \u0000betalains only in Amaranthaceae which presupposes that taxonomic relevant ergastic substances \u0000demarcation lines may exist to delimit the families. In addition, these ergastics substances \u0000showcase the taxa potential food, health and industrial applications. The Amaranthaceae- \u0000Chenopodiaceae starch granule is small in size (0.7-5.4 μm), circular in shape (poorly irregular) and \u0000lacks hilium and striations. The small-size granule will be invaluable for a number of prospective \u0000food and health uses, principally for low glycemic load foods for diabetics, as well as numerous \u0000industrial uses, such as producing environmentally friendly biodegradable plastics as alternatives \u0000to petrochemicals.","PeriodicalId":275718,"journal":{"name":"Research Journal of Botany","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125536252","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}
