Abstract:
... The objective of this study was to evaluate the effects of abscisic acid (ABA) related to the increase of water-stress tolerance in two drought contrasting maize hybrids: DKB 390 (tolerant) and BRS 1030 (sensitive). The characterization of water status (pre-dawn leaf water potential, Ψₚd; midday leaf water potential, Ψₘdand stem water potential, Ψₛₜ) and antioxidant enzyme activity was conducted o ...

Abstract:
... To study the effect of an exogenous cytokinin application on safflower yield, an experiment was conducted in 2012–2013. Two cultivars of safflower (Goldasht and Zendehrood) and five concentrations of 6-benzylaminopurine (BAP) (0, 25, 50, 75, and 100 μM) were applied at the flowering stage. Results indicated that the application of 75 μM of BAP showed increased seed and oil yield by 17.54 and 18.29 ...

Abstract:
... In this study, we investigated the effects of foliar applied salicylic acid (SA) on protecting wheat (Triticum aestivum) from heat and high light stress during the grain filling stage. Specifically, the Photosystem II (PSII) photochemistry of wheat flag leaves under the treatment of SA was studied as indicators for stress response. Our results indicated that under stress, SA-supplemented wheat pla ...

Abstract:
... The rice stunted lemma/palea 1 (slp1) mutant displays a dwarf, shortened panicle length, degenerated lemma and palea, and sterility. A previous study suggested that a missense mutation at the sixth amino acid of the OsSPL16 protein was likely to be responsible for the slp1 mutant phenotype. The current study shows that the overexpression of the wild-type OsSPL16 allele in slp1/slp1 and Slp1/slp1 m ...
