The aim of the research was to evaluate the response of latex production at various times application in multiple clones rubber plant to giving several sources hormone ethylene. The experiment was conducted in October 2013 to March 2014 in Sungei Putih Rubber Research Institute, Galang Subdistrict , Deli Serdang regency. Three-Stage Nested Design was applied with three replications. The first step was time application, i.e., a first application, a second application, a third application, and a fourth application, the second step was clones treatment, i.e., IRR 118 clones, PB 260 clones, IRR 42 clones, IRR 39 clones and the third step was stimulants treatment, i.e., without stimulants, ethrel, SP1, banana peel extract and extract of pineapple skin. Observed parameters was the latex volume. The study showed that time application had no significant increased on latex production, and clones treatment at various times application had no significant to produce on latex production, whereas stimulant treatment in multiple clones at various times application significantly increased latex production. IRR 39 clones were clones that experienced the highest increase in producing due to the provision treatment of stimulants. SP1 was a stimulant that increases the production of the highest latex. Ethrel, banana peel extract was a stimulant that can increase the production of latex higher than without stimulants. Pineapple peel extract resulted in clumping of latex flow on tapping grooves and a low yield of latex productio

Distinguishing rift-related from inversion-related anticlines: Observations from the Abu Gharadig and Gindi Basins, Western Desert, Egypt

Distinguishing the tectonic origin of anticlinal structures is problematic in regions with a complex history of rifting and inversion. We present the results of seismic mapping, in the form of time-depth (isochron) and time-thickness maps to characterize how sedimentary thickness differentials evolved in response to normal faulting and to inversion events on faults within the Abu Gharadig and Gindi Basins in the Western Desert of Egypt. Late Cretaceous rift-related faults in the Abu Gharadig Basin strike NW-SE, W-E and SW-NE. In the eastern part of the basin, a prominent SW-NE trending interbasinal saddle formed in response to preferential subsidence forming half-grabens to its north-west and southeast, during the Mid-Turonian to Santonian interval. Santonian to Palaeogene inversion in the Abu Gharadig Basin developed on its northern basin margin, the absence of SW-NE striking faults in the eastern central basin resulting in any inversion effects being minor. In the central Gindi Basin, Upper Cenomanian to Lower Turonian SW-NE striking rift faults underwent inversion as early as the Mid-Turonian. The orientation of existing rift faults and modification of the local stress fields control the extent to which inversion was taken up in each basin trough time. The Abu Gharadig and Gindi Basins are two of the rift basins developed in West and Central Africa that underwent rifting, inversion and dextral shearing during the Late Cretaceous. We emphasize the value of high-resolution stratigraphic mapping to characterize short-lived and subtle pop-up events that may have gone unnoticed
