By examining R~5000 spectra taken with the WIYN+Hydra spectrograph, we identify 3 PN candidates in a sample of 274 likely globular clusters, 2 candidates in objects which may be globular clusters, and 5 candidates in a set of 85 younger systems. The possible PNe are all faint, between ~2.5 and ~6.8mag down the PN luminosity function, and, partly as a consequence of our selection criteria, have high excitation, with [OIII]{lambda}5007 to H{beta} ratios ranging from 2 to >~12. We discuss the individual candidates, their likelihood of cluster membership, and the possibility that they were formed via binary interactions within the clusters. Our data are consistent with the suggestion that PN formation within globular clusters correlates with binary encounter frequency, though, due to the small numbers and large uncertainties in the candidate list, this study does not provide sufficient evidence to confirm the hypothesis.2013ApJ...769...10Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/769/10CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/143 : Revised Bologna Catalog of M31 clusters, V.5 (Galleti+ 2012)J/AJ/148/4 : JHK photometry of 913 globular clusters in M31 (Wang+, 2014)J/AJ/147/16 : Spectroscocpy of planetary nebulae in M31 (Kniazev+, 2014)J/AJ/146/20 : Structural param. for globular clusters in M31 (Wang+, 2013)J/A+A/549/A60 : Ages and [Fe/H] of M31 globular clusters (Cezario+, 2013)J/A+A/544/A155 : HST photometry of M31 globular clusters (Federici+, 2012)J/AJ/143/87 : IRAC phot. of massive M31 globular clusters (Barmby+, 2012)J/AJ/143/14 : Lick indices of M31 globular clusters (Schiavon+, 2012)J/ApJS/199/37 : GALEX catalog of star clusters in M31 (Kang+, 2012)J/A+A/534/A55 : Deep XMM-Newton Survey of M31 (Stiele+, 2011)J/AJ/141/61 : Star clusters in M31.
