ANALYSIS OF THE RELATIONSHIP BETWEEN TEMPERATURE AND GERMINATION OF SWEET PEPPER |

| Abstract:
Sweet pepper seed was sown at various temperatures. For the germination percentage (p) versus time (t) a logarithmic equation was applied viz. p = A [1-e-k(t-to)], in which A represents the maximum germination percentage, k is a value for the time spread in the seed population for germination and to is the time for the first seed to germinate. It appears that a heat sum concept could be applied for germination taking into account values of to. Since k was relatively constant, the time to achieve a certain germination percentage depends on a heat sum until to and a fixed number of hours independent of temperature. Some practical consequences have been discussed. | |
