Fruit development was affected by climate, flower initiation and pollination process. This study aimed to determine the correlation between climate, position, distance of pollen donor to female nutmeg trees, and the ratio of female and male trees to nutmeg yield. The study was conducted at the nutmeg germplasm collection garden at Cicurug (550 m asl), Sukabumi, tested 295 nutmeg trees from 27 locations in Indonesia. Data production of female trees was based on 2005-2017 data. All nutmeg trees were mapped using the GPS Garmin 76c5x. Tree sex was determined by male or female flowers domination in each tree. Correlation of the climate factors and production was analyzed using Pearson Correlation. The distance, position and the proportion of female to male trees were evalated by t-test at 5% level. Ratio of female and male trees to produce high yield was 4 : 1. Rainfall (280-430 mm/month) and temperature (24 - 25o C) during the pollination period (8-7 months before harvesting) were positively correlated with production by 57.9 % and 82.3 %. The position and distance of pollen donors to female trees had no effect on production. However, the distance between pollen donors and female trees above 15 m produced an average production equal to 15 m. The number of trees around tree samples had no effect on nutmeg production, but light intensity at 61,425-88,480 lux absorbed by trees could enhance the yield. Nutmeg required sunlight to penetrate plant canopy in order to induce fruit production.","PeriodicalId":32447,"journal":{"name":"Buletin Penelitian Tanaman Rempah dan Obat","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45750363","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}

The research aimed to obtain endophytic bacteria potential to stimulate the growth of black pepper seedling. The first step was isolating endophytic bacteria from roots, rhizomes, and leaves of healthy red ginger. Characterization and selection were conducted by evaluating the capability on phosphate solubilization, nitrogen fixation, and indole acetic acid (IAA) hormone production of the isolated endophytic bacteria. There were 36 isolates consisted of 14 isolates from leaves, 9 isolates from roots and 13 isolates from rhizomes. Seventeen isolates were capable to dissolve phosphate, fix nitrogen and produce IAA or possessing those three characters, but only nine isolates were tested on pepper seedlings. The nine isolates were Ajc 1, Ajc 3, Ajc 7, Ajc 9, Rjc 1, Rjc 6, Djc 3, Djc 6, and Djc 11. Further evaluation of the nine isolates which were inoculated to pepper seedlings, indicated that Rjc1 isolate enhanced pepper seedlings height better than other isolates.","PeriodicalId":32447,"journal":{"name":"Buletin Penelitian Tanaman Rempah dan Obat","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47038327","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}

The widespread cultivation of nutmeg cause the high demand for nutmeg seeds, hence the source of quality seeds is needed. The purpose of this study was to evaluate sex, morphological characters, yield and quality to be recommended as source of quality seeds. The research was conducted at Cicurug Experimental Station, Sukabumi (550 m asl). The parameters observed were the sex of trees, and yield per tree harvested for nine years from 2007-2015. The quality was analyzed using Gas Chromatography Mass Spectra (GC-MS). The sex of the trees observations resulted 152 accessions (34.7 %) were pure males, 83 accessions (18.9 %) bisexual males and 203 accessions (46 %) pure females. Based on fruit yield, from 203 female nutmeg trees, 20 accessions produced high fruit yield >2,500 fruits/tree/year. GC-MS analysis showed the number of identified compounds were 18-30 compounds with the main components were α-pinene, ß-pinene, sabinene, limonene, 4-terpineol, safrol, elemicin and myristicin. The 20 selected accessions met the quality standards for the essential oil, limonene and elemicin levels, but only five accessionsmet the standard quality for α-pinene, two accessions for ß-pinene, five accessions for sabinen, 18 accessions for 4-terpineol, 13 on safrol, and 11 accessions for myristicin levels. Tree selected accessions Botol 122, Irian 112 and Kupal 139 fulfilled nine out of ten quality parameters, whereas other accessions only fulfilled eight to four quality parameters.

Young ginger rhizomes rapidly shrank and decrease their viability. The experiment was aimed to study growth patterns, biochemical changes, and physiology of ginger plants to produce good quality rhizome seeds. JPB rhizome seeds used were 9 months old, have been stored for 2 weeks after harvest, weighed 30-40 g with 2-3 buds, healthy, and given seed treatment. The rhizomes were planted in growth medium in polybags (60 cm x 60 cm). The study was conducted by direct observation, repeated 4 times, consisting of 50 plants per replication. Observations were made on the plant growth patterns (plant height, stem length, tillers number, leaves number); rhizome development (fresh weight, branch rhizomes number, moisture content, and dry weight during growth); starch and hormonal content (IAA, gibberellin, ABA and cytokinin) of the rhizomes; and viability of rhizome seeds (growth rate, seed height, and dry weight). The results showed that the rhizomes of the 7-month-old ginger after planting (MAP) has entered the ripening phase, the rhizome morphology was optimal, and the starch content was not different from the rhizome seeds at 8 and 9 MAP. In addition, physiologically, the rhizome's growth potential was maximal (100%), growth rate (4.3% etmal-1), and seed height (33.8 cm) were better than 8 MAP (80%, 2.9% etmal-1, 33.7 cm) and 9 MAP (70%, 2.3% etmal-1, 29.4 cm). This study indicated that ginger rhizomes harvested from 7 months old plants can be used for seeds.","PeriodicalId":32447,"journal":{"name":"Buletin Penelitian Tanaman Rempah dan Obat","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45091401","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}
