Capsicum annuum

Genus Capsicum

This source reports two treatments. Both are shown.

Protocol 1

DerivedN. C. Deno, 1996

Difficulty Low Rated by us, not by the source.

Start around March 22, 2027 for a May 3 last frost.

  1. Sow and cover

    Temperature: 70°F 21°C Light: light

No stated waiting before sowing. Then 14 days to germinate.

100% germination in 14 days.

Capsicum (Solanaceae). It was reported in the 2nd Ed. that seeds of the green, yellow, and red forms all germ. in 9-11 d after removing from the fruit and after a WC as brief as 2 hours. It was proposed that possibly a germination inhibitor was somehow being transmitted into the seed inside the fruit. This has now been shown to be incorrect. What happens is that the fruit simply blocks access of oxygen to the seed. Thus the seed germ. 100% in 2-8 d in 70D with all three forms after removing from the fruit and placing in the moist paper towels. It made no difference whether the seeds were taken directly or WC for various times up to 8 d. In fact the seeds germ. under water in the WC treatment almost as fast as when in the more aerated paper towels. This result is in contrast to the behavior of the Casaba melon (cucumis melo) where seeds totally fail to germinate under water. The difference is attributed to the melon seeds requiring large amounts of oxygen whereas the Capsicum seeds are smaller and require less oxygen and are able to extract the needed oxygen from the water. Seeds of the yellow form showed no significant deterioration after 2 y DS. C. annuum germ. 70L(100% in 2nd w) and 70D(70% in 2nd w). GA-3 had no effect. Presumably germination is prevented inside the fruit by blocking access to oxygen as described above for
