Quality and Storability of Waxy Corn Seed

Abstract

The objective of this study is to determine the quality and storability of waxy corn seed from three locations where waxy corn is normally cultivated. The experiment was conducted at the waxy corn planting of Tambon Ban Koh in Phra Nakhon Si Ayutthaya province during February to May 2004 and the Department of Agricultural Science, Fculty of Science and Technology, Phranakhon Si Ayutthaya Rajabhat Universityduring June 2004-March, 2005. Samples of the waxy corn seeds were planted in three locations namly villages 1, 3 and 4. Harvesting was made at physiological maturity stage and seeds were dried under bag and stored under control condition for 300 days. Seed germination, speed of germination index, seed weight, seed moisture content to 10%. Dried seeds were put in a plastic bag and stored under control condition for 300 days. Seed germination, speed of germination index, seed weight, seed moisture content, stem length, root length, shoot dry weight and electrical conductivity were tested at 60 days intervals. The results showed that 96.50% germination over 90 % after 300 dys of storage.
