Physiological and Biochemical Responses to Drought Stress and Subsequent Rehydration in the Symbiotic Association Peanut-Bradyrhizobium sp.

Table 3

Influence of drought stress and rehydration on peanut nodulation and nitrogen content.

Treatments	Nodule number	Nodule DW (mg)	NNW	SNC (mg plant^−1)
Control	41.85 ± 2.92^a	22.24 ± 2.62^a	0.018 ± 0.003^a	23.52 ± 2.84^a
Drought stress	29.15 ± 1.50^b	15.83 ± 1.08^b	0.019 ± 0.001^a	10.14 ± 1.88^b
Rehydration	33.57 ± 2.14^b	16.65 ± 1.37^b	0.023 ± 0.003^a	10.42 ± 0.43^b

NNW: normalized nodule weight; SNC: shoot nitrogen content. Values are means ± S.E. (𝑛=12). Different letters in each column indicate significant differences at 𝑃<0.05 according to LSD Fisher’s test.
