DKI Jakarta as a Capital City has been existed since 1527 which has various under ground infrastructures. The limitations of underground information can cause lack of spatial use and the risk of accident caused by underground infrastructure.

Bulk seed samples were collected and examined for variations in number of seeds per cone, seed length, width, 1000-seed weight and germination in the laboratory and nursery. In the laboratory, the effect of light conditions on seed germination was tested by incubating the seeds under continuous light or darkness. Significant variations ( p < 0.05 for all traits) among J. procera populations were detected for all seed characters: number of seeds per cone, seed length, width and 1000-seed weight. Germination in the laboratory also varied significantly among populations ( p = 0.012) as well as light conditions ( p = 0.037). The overall germination performance of seeds incubated under continuous light was significantly higher than seeds incubated in darkness. However, seeds from some populations germinated equally well in light and darkness, suggesting that photo-dormancy in juniper seeds varies between populations. Germination of seeds sown on nursery beds was relatively lower than seeds germinated under continuous exposure to light in the laboratory. Among geo-climatic variables, the mean annual rainfall of seed collection sites displayed a significant correlation with number of seeds per cone (r = 0.71; p < 0.05) and seed length (r = 0.73, p < 0.05), and between longitude and rate of germination (r = 0.73, p < 0.05). A significant intercharacter correlation was also found between seed length and seed width (r = 0.78, p < 0.05), and between seed weight and number of seeds per cone (r = 0.91, p < 0.01). It can be concluded that the observed patterns of variation will have an important implication for gene conservation and tree improvement program of the species in the future. #

Extracts from different plant parts of Amorpha fruticosa, A. nanna, and A. canescens gave several spots with color and Rf values similar to those of Cannabis sativa extract. The major compound, amorphastilbol (1), was isolated by column chromatography, purified, and characterized by mp, elemental analysis, uv, ir, mass, prm, and cmr spectroscopy. Further information was obtained by analyzing the oxidation products of the compound. The evidence indicates that amorphastilbol is a phenolic stilbene terpenoid with a molecular formula of C24 H28 O2 and structural formula: (E,E)-2-(3&amp;amp;#39;,7&amp;amp;#39;-dimethyl-2&amp;amp;#39;-6&amp;amp;#39;-octadienyl)-5-(2-phenylethenyl)-1,3-benzenediol. This is the first report of the isolation of a naturally-occurring stilbene derivative possessing a terpenoid moiety.

The younger women exhibited significantly higher levels of each androgen, the differences being almost entirely attributable to ovarian failure in the older group. Although the older women reported the same levels of sexual desire and sexual arousal as the younger women, their intercourse frequencies and self-rated sexual gratification scores were significantly lower than the values obtained for the younger wives. One or more of the androgen levels related significantly and in the expected direction to each stage of the four-stage sexual response process. Global measures of so-called &quot;sexual adjustment&quot; and estimates of anxiety, depression, and hostility feelings experienced by these women did not relate significantly to any of the four androgen levels.

Here we examined the effects of seed sources and storage temperature on the longevity of Juniperus procera seed lots through collection and preservation of seeds in seed banks. Seeds were collected from nine sites across the species natural distribution in Ethiopia and stored in four warehouses: modern cold room (5°C), mud house (15°C), concrete block house (17°C) or corrugated iron house (20°C) for 42 months. Every three months, a random sample of stored seeds were drawn and tested for germination. A highly significant variation (p 0.80; p
