Plant growth response of japonica rice (Oryza sativa L.) cv. Dongjin under no stress (NS) and prolonged heat stress (HS) with or without endophytic Paecilomyces formosus LWL1

Treatment	Plant height (cm)	Fresh weight (g)1	Dry weight (g)2	Chlorophyll content (SPAD)3
No stress (NS)
Control	21.85±1.00	26.89±1.24	1.43±0.08	31.61±1.63
P. formosus LWL1	25.57±0.88*	40.78±0.89*	1.93±0.05*	36.03±1.08*
Heat stress (HS)
Control	19.86±1.55	18.56±1.29	1.01±0.02	34.09±1.20
P. formosus LWL1	23.43±1.48*	27.90±1.03*	1.49±0.03*	43.23±0.89*

¹Fresh weight per 30 plants (shoot and root).

²Dry weight per 30 plants (shoot and root).

³Soil-plant analysis development (SPAD) unit for measuring leaf chlorophyll content. The effects of P. formosus LWL1 on the growth of Dongjin (GAs normal) rice cultivars under normal environmental conditions (no stress) have been previously reported by Waqas et al. (2014).

^*Significant differences between plants treated with and without P. formosus at the P<0.05 level by Student’s t-test. The experiment was independently repeated three times and values of respective treatments were pooled together to calculate the mean±SD. In each experimental repetition, 30 plants were randomly selected per treatment from three replicates
