| Summary: | 博士 === 國立中興大學 === 生物產業機電工程學系 === 93 === This study was conducted to discover the treatment demands after
harvesting and grading for Gladiolus corms. The following key
techuiques, which were dormancy breaking, respiration rate, ERH/EMC,
and Germination rate, etc., were developed. This study did include the
study on growing rates and growth models of Gladioulus corms. The
values of ERH for fresh Gladioulus croms were greater than 0.9. If the
relative humidity in a storage room exceeded 90%, it would not only
induce the attacks of mold and bacteria on the flower corms but also
retard the germination of flower corms. Therefore, it was necessary to
lower the relative humidity to 70-80% in order to storage the corms
properly.
The experiments were executed to find out the effect of storage
period on breaking dormancy of flower bulbs of Gladiolus in 50C. The
non-linear regreesion technique was used to analyze the data. The related
mathematical model for dormancy breaking and germination rate was
established. The optimal technique was applied to compute the shortest
period for cold strage. The experimental results showed the longer cold
storage period is, the better germination homogeneity and time were. For
shortening the germination time and increasing the germination
homogeneity, the cold storage period had been extended.
In this study, the growth characteristics of Gladiolus with four
treatments were recorded. These data were analysis by non-linear
regression technique to establish growth models. These models were
tested and compared on the effect of treatments via F statistics. The
results indicated that three growth models of stem length and logarithm
leaf area were acceptable. The sizes of corm and plant depths did
significantly influence the growth characteristics of Gladiolus.
