The sttdy ofparthenocarpy ]l.'as conducled by applying o plant grott'th regulator on several horlicultural commodities- One of the pldnl groilh regulalors is auxin. That v'as why auxih wos dpplied and used on Pondoh sallaca for partehocarp Ji'uit setting. The experimental method used in lhis research was arranged in a conpletely randonized design (CRD). This research consisled of three erperinenls. The frsl is the khds (lAA and 2,4-D) and the concentrations (100, 200 and 300 ppm) of auxin aplicalion. The second is lhe concentrations of 2,4-D (100, 200 and 300ppm) applied on spadic ofJully and 25% opened inflorescence. And lhe lhird experimcnt is lhe methods and the concenlralion of 2,4-D aplicalion ie. Spray method (concentration 0,0196, 0,002% and 0,003%") ahd pastd melhod (concenlration 0,lt%, 0,2% and 0,3%). Each experiment was followed by antophogamic pollination as control- AJter lhe applicalion, the Jlowers n'ere corered by a plastic lo prevent natural pollination. The study resuh shou,ed that auxin application (lAA and 2,4-D) did not produce seedless Pondoh Sollaca. However, this study produced o new Jinding that aurin could be used as an auernalive of pollen when production of pollen of Sallaca flower was limited. Besides, lhe auxin could also be used as a preservative substance Ior lhe viabilily of pol len. Keyword: Plant Growth Reguldtor, parthenocarp ahd sallaca
