The Chemical Control Effects of GZS on the Sweet Maize

doi:10.3321/j.issn:1000-7091.2002.z1.015

Abstract

Abstract: Both seedling experiment and farm experiment showed that to spray sweet maize leaves with 750 mg·L ^{- 1} GZS composed mainly of allantoin (a kind of cytokinins of urea derivatives) could obviously increase root number?root length?root weight?plant height?stem diameter?leaf area and leaf spesific gravity.At the same time,the chlorophill content and bleeding fluid were increased.On the basis of cultivating strong seedlings GZS also promoted the reproduction that the blossom and maturity were earlier than control and the yield had increased by 20% and more.

Key words: Sweet maize, GZS, Allantoin, Chemical control
