Abstract
Pepper seeds are slow to germinate and emergence is often non-uniform and incomplete, reducing gains
from this cash crop. This study investigated the effects of
pineapple stem- derived protease (stem bromelain) based
priming on pepper seed germination in relation to reserve
mobilization (specifically, proteins and amino acids), germination, emergence and plant growth. These parameters
were compared across two controls, (1) unsoaked seeds and
(2) seeds soaked in deionized water, and seeds soaked in
pineapple stem bromelain crude extract (treatment). Seeds
were soaked in bromelain crude extract possessing a proteolytic activity of 6.25 tU or deionized water (first control)
for 3 h at 35 C. Light microscopy revealed an abundance
of protein bodies in the endosperm of the seeds prior to
imbibition.
