TABLE 3.

Suppression of Pythium seed rot of cotton by wild-type and fatty acid mutant strains of E. cloacae

E. cloacae strain	Seedling standa (%)	Seedling qualityb
Noninoculated Control	86.7	2.5
Nontreated (Pythium only)	6.7*	0.8*
EcCT-501R3	93.3	3.0
Ec31	6.7*	0.4*
Ec31(pKV311)	86.7	2.6
EcL1	13.3*	0.8*
EcL1(pKVL16)	80.0	2.4

^aSeedling stands determined 7 days after sowing. Percent stands are based on five individual seedlings per treatment. The results are the means of three replicate experiments. Values followed by an asterisk differ significantly from the noninoculated control according to simple t-tests. 

^bDisease severity rated as on a scale of 0 to 3, where 0 = no seedling emergence or emerged seedling but completely covered with mycelium; 1 = the emerged seedlings failed to develop and had visible mycelial growth; 2 = seedlings appeared healthy but had visible mycelial growth or seedlings were less vigorous than those in the noninoculated control cylinders; and 3 = seedlings were healthy and had no visible signs of mycelial growth. Values followed by an asterisk differ significantly from the noninoculated control according to the Mann-Whitney test.
