“…An improved yield effect due to zeolite addition also was found in Brassica napus plants by Shahsavari et al (2014Shahsavari et al ( , 1813, since the greatest proportions of all studied traits were attained by applying Z2Zn2 (15 t ha -1 zeolite and 0.1% Zn sulfate). The rates of grain yield, biological yield, and harvest index improved by 43.8 %, 73.9 %, and 30.0%, respectively, by the pooled application of Z and Zn.…”

Zeolita clinoptilolita es un aluminosilicato hidratado que pertenece a un grupo de minerales de origen volcánico y posee propiedades agrícolas interesantes. El objetivo de este trabajo fue determinar el efecto causado por la zeolita en plántulas de tomate (Solanum lycopersicum Mill.) cultivadas en macetas. Por lo tanto, se evaluaron las propiedades físicas de tres sustratos: peat moss (pm), perlita (per) y zeolita (zeo), y sus diferentes mezclas (pm:per:zeo) en los siguientes tratamientos: (T1 o Control) = 100:0:0; T2 = 70:30:0; T3 = 70:20:10; T4 = 70:10:20 y T5 = 70:0:30 (v/v). Comparado con el tratamiento control, los sustratos conteniendo 30% de zeolita incrementaron su capacidad de retención de agua (260%), porosidad total (8.47%), densidad aparente (212%) y la densidad de partículas (230%). En comparación con las plantas desarrolladas en el sustrato control (100% peat moss), las que fueron cultivadas con 30% de zeolita incorporada al sustrato, exhibieron valores estadísticamente superiores en altura (24.2%), área foliar (64.5%), longitud de raíz (63.2%), biomasa seca aérea (62.5%), biomasa seca de raíz (208.9%), diámetro de tallo (28.5%) y número de hojas (92%); sin embargo, el índice de clorofila no mostró efectos significativos. Los resultados claramente indican que la incorporación de zeolita en los sustratos puede promover el crecimiento de las plantas de tomate.

“…Moreover, concentration of oleic acid and linoleic acid was also remained unaltered with Zn fertilization but was influenced by the crop cultivar. Shahsavari et al (2014) reported a significant effect of Zn on seed oil properties, but they used different sources of Zn with much higher concentration which might be the reason for contrasting results. The effect of Zn fertilization was significant (P < 0.05) for concentration of oleic acid only in the second year which depicts a strong effect of environment on crop response to fertilization (Al-Naggar et al 2015;Humbert et al 2016), and it strengthens our contrasting results.…”

“…Zinc is an essential micronutrient for production of proteins in plants, and it is reported that optimal application of it can increase the oil and protein contents of oil seed crops (Bybordi and Ebrahimian 2013;Shahsavari et al 2014;Shahsavari and Dadrasnia 2016). Zn is also a main component of ribosomes and essential for their development (Clemens 2010) and plays an important role in cellular processes.…”

Zinc (Zn) is an important micronutrient for plants, but mostly, soils do not have enough amounts of Zn available. This necessitates the application of supplementary Zn for proper growth and development of plants. Canola is an important oilseed crop of the world, but its yield attributes, protein and oil contents, and fatty acid composition are always being investigated for improvement under various agroclimatic conditions, which was the major objective of this study. This 2-year field experiment was conducted to evaluate the efficiency of soil applied Zn and cultivars for yield attributes and seed oil quality of canola. Treatment included four canola cultivars viz., Faisal canola, Pakola, PARC canola, and Rainbow factorally combined with three zinc levels (0, 5, and 10 kg ha −1). Zn fertilization improved yield attributes and yield of the canola cultivars, but cultivars differed in their response to Zn fertilization. Rainbow cultivar produced 24-27% higher seed yield at 10 kg ha −1 Zn as compared with control treatment. In addition, Pakola cultivar attained 0.5-1.5% higher oil contents at 5 kg ha −1 Zn when compared with the control treatment. However, soil applied 5 and 10 kg ha −1 Zn did not show any significant influence on protein contents of all canola cultivars. Zinc fertilization increased the seed yield and yield components of canola cultivars and significantly enhanced the oil contents. Rainbow cultivar was found to be the most responsive to Zn fertilization regarding the seed yield and oil contents and its fatty acid composition and economic returns.

Background: Chorispora bungeana (C. bungeana) is a typical subnival alpine species, which shows high tolerance to multiple abiotic stresses. Phospholipase D (PLD) is a crucial enzyme participated in membrane phospholipid catabolism. In this study, to explore the function of CbPLDγ in drought stress, we cloned and characterized a CbPLDγ gene, which is a part of CbPLD gene family and from C. bungeana.Methods: Use the gateway method for vector construction, using DNAstar software, PCR machine, centrifuge, pipette, electrophoresis, gel imaging system, spectrophotometer, confocal microscope, etc. Spss, Orgin software for statistical analysis.Results: The CbPLDγ gene encodes 859 amino acids containing "FIYIENQYF" domain and two HKD domains. Bioinformatics analyses showed that the CbPLDγ is highly homologous with PLDs from other plant species. Real-time quantitative PCR (qRT-PCR) and Beta-glucuronidase (GUS) assay showed that CbPLDγ was accumulated dominantly in roots and stems. Compered with the control, the expression pattern of the CbPLDγ mRNA is in response to low temperature, salt, mannitol, and exogenous ABA have up-regulated. Subcellular localisation analysis showed that the CbPLDγ was localized in the cell membrane. Compared with wild-type Arabidopsis thaliana, CbPLDγ gene overexpression plants showed higher activities of antioxidant enzymes, and lower levels of malonidiadehyde content and electrolyte leakage under drought stress.Conclusions: In this study, novel PLDγ gene was amplification from C. bungeana and was called CbPLDγ. These confirmed that CbPLDγ involved in the response to drought stress, and has the potential to improve the drought tolerance of plants. This is the first report about cloning and characterizing the gene of CbPLDγ from C. bungeana. It laid a foundation for further research and improvement of the PLD gene family of C. bungeana.
