Differential responses of contrasting low phosphorus tolerant cotton genotypes under low phosphorus and drought stress.

ABSTRACT:

Background

Drought is one of the main reasons for low phosphorus (P) solubility and availability.

Aims

The use of low P tolerant cotton genotypes might be a possible option to grow in drought conditions.

Methods

This study investigates the tolerance to drought stress in contrasting low P-tolerant cotton genotypes (Jimian169; strong tolerant to low P and DES926; weak tolerant to low P). In hydroponic culture, the drought was artificially induced with 10% PEG in both cotton genotypes followed by low (0.01 mM KH₂PO₄) and normal (1 mM KH₂PO₄) P application.

Results

The results showed that under low P, PEG-induced drought greatly inhibited growth, dry matter production, photosynthesis, P use efficiency, and led to oxidativ
