The Impact of Drought and Vascular-Inhabiting Pathogen Invasion in Pinus taeda Health

Table 8

Least square means and standard errors of various response variables of seedlings from two different families receiving three different watering treatments.

Variable	Family	Normal watering	Moderate drought	Severe drought
		Mean ± SE (cm)	Mean ± SE (cm)	Mean ± SE (cm)
HTI	Tolerant	23.99 ±2.07a	24.09 ±2.07a	19.01 ±2.07b
	Susceptible	17.16 ±2.08b	17.24 ±2.07b	15.7 ±2.06b
FRY	Tolerant	1.57 ±0.17a	1.15 ±0.16ab	0.94 ±0.17ab
	Susceptible	1.01 ±0.17ab	1.04 ±0.17ab	0.71 ±0.17b
Sy	Tolerant	5.70 ±0.18a	5.05 ±0.17a	4.14 ±0.17ab
	Susceptible	3.92±0.18b	3.79 ±0.17b	2.97 ±0.17b

Note. SE: standard error, HTI: height increase, FRY: fine root dry biomass, and Sy: stem dry biomass. Different letters indicate Tukey pair-wise differences between all family and watering treatment conditions within each variable at α = 0.05.
