Fig. 2. Latency and duration of egg-laying in response to a number of stimuli. (A)
Latency to the start of egg-laying in response to the NO donor, and in
response to large hermaphroditic duct (LHD) homogenate, bag cell (BC)
homogenate, and egg-laying hormone (ELH). Data for these treatments were
combined. Latency in response to the NO donor was significantly shorter than
in response to LHD homogenate, BC homogenate and ELH. (B) The duration of egg
laying in response to the NO donor versus the other treatments. The
duration of egg-laying in response to the NO donor is significantly shorter
than in response to the BC homogenate. (C) Application of the NOS (nitric
oxide synthase) inhibitor L-NAME
(N
-nitro-L-arginine methyl ester) significantly
increased the duration of egg-laying in response to the LHD homogenate.
