SOME FACTORS AFFECTING GERMINATION OF CELERY SEED

Abstract

Introduction Some of the germinatioll eharacteristies of celery seed are of practical iiiiportance because they dictate cultural practices which are expensive and more exacting, than are required for many other crops. Better understand-inrg of the factors affecting the rate of germination should lead to possible treatments which shorten the pre-emergence period and simplify cultural requirements. Light, alternating temperatures, moisture, etc., are known to affect the germination oI the seed, 1, 2, 3, 8, but in these studies the interactions of the several factors and their effect on the rate of germination were not investigated or reported. In the case of kok-saghvz and guayule seed, the difficulties due to slow germination were overcome by presprouting 4, 5. In this paper are given
