- 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 ...

To understand how light quality influences plant photosynthesis, we investigated chloroplastic ultrastructure, chlorophyll fluorescence and photosynthetic parameters, Rubisco and chlorophyll content and photosynthesis-related genes expression in cucumber seedlings exposed to different light qualities: white, red, blue, yellow and green lights with the same photosynthetic photon flux density of 100 ...

- 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 ...

To clarify the intricate relationship of H₂O₂-induced leaf senescence with distinct CAT gene expression, the genotypic-dependent alteration in the temporal patterns of H₂O₂ content, malondialdehyde (MDA) accumulation, relative conductivity, and the transcript expression of three CAT isoform genes during leaf senescence was investigated using two rice genotypes, namely, the early senescence leaf (e ...

The aims of the present study were to identify and functionally analyse the soybean GmHKTs gene family, and to explore their roles under NaHCO₃ and NaCl stresses. The GmHKTs gene family were isolated from soybean using genome sequence information. The GmHKTs gene family were further analysed for ...

- Abstract:
- ... Moringa oleifera is a multipurpose plant which is now being promoted as a fodder crop. The present study was conducted to induce the tolerance in moringa plants to emerge and grow under saline conditions. For this, moringa seeds were primed with aerated water (hydropriming) and moringa leaf extract (MLE) for 12 and 24 h and studied for its emergence, potential growth behaviour, mineral composition ...

In our study, we investigated whether multiple fluorescence indices may be used to sense physiological changes in tomato plants (Solanum lycopersicum L.) caused by salinity and water deficit as single or combined stresses. The fluorescence intensity in the blue (B), red (R) and far-red (FR) spectral regions and the pulse-amplitude-modulated (PAM) chlorophyll fluorescence, were recorded on a weekly ...

The present report describes the effect of 3-cyclopropyl-1-enyl-propanoic acid sodium salt (CPAS—WO 2010/0822930), a novel water soluble ethylene antagonist, on senescence and grain yield of several cultivars of common wheat (Triticum aestivum L.) and durum wheat (T. durum Desf.). CPAS abolished ethylene-induced leaf and ear organ senescence, as evidenced by the inhibition of chlorophyll degradati ...
