 WATERMELON PLOTS (SLUT-HRIES OF EXPERI:IENTAL WORK)

_1. Maleic Hydrazide as a Male Blossom Suppressant

 Purpose: to determine whether maleic hydrazide under Florida
 field conditions might suppress production of male blossoms.


Treatments:
rows 2-10:
 11-19:
 20-28:


MH at 1000 6000 ppm, 3 applications
MH at 1000 6000 ppm, 2 applications
MH at 1000 6000 ppm, 1 application


Results: IH suppressed vegetative growth and delayed flowering,
particularly at higher concentrations, but male blossoms, with
apparently fertile pollen, vere produced eventually even after
3 applications at 6000 ppm.


Observational Plots, including Southeastern Regional Entries.


Dates of planting: February 21;
Cannonball, March 16.
