Globally, drought and salinity stress critically constrain potato (Solanum tuberosum L.) production. Considering the impact of these stresses on crops and increasing food demand, insight into both tolerance and susceptibility is essential. The present study screens two potato cultivars, BARI-401 and Spunta, for their tolerance to simulated salinity...

Globally, many crop production areas are threatened by drought and salinity. Potato (Solanum tuberosum L.) is susceptible to these challenging environmental conditions. In this study, an in vitro approach was employed to compare the tolerance of potato cultivars ‘BARI-401’ (red skin) and ‘Spunta’ (yellow skin). To simulate ionic and osmotic stress,...

The World Health Organization (WHO) declared the COVID-19 as a pandemic disease due to its rapid spreading worldwide, caused by a novel coronavirus (SARS-CoV-2) that has brought about many fatalities. Until now, no effective treatment in the form of anti-virus medication or vaccine has been available for the disease. Therefore, this review aimed to...

The effect of different concentrations of IBA and NAA at 0, 1000, 3000, 6000 and 9000 ppm on rooting of olive cuttings collected at three different seasons (autumn, winter and spring) were examined under arid land conditions. Cuttings collected in autumn (November) and winter (January) showed similar responses for percentage of rooting (39.33 & 44....

Humic substances (HSs) have considerable effects on soil fertility and crop productivity owing to their unique physiochemical and biochemical properties, and play a vital role in establishing biotic and abiotic interactions within the plant rhizosphere. A comprehensive understanding of the mode of action and tissue distribution of HS is, however, r...

To set a definite micro-propagation protocol for olive has always remained a challenging task owe to its woody nature. This study was consist of different olive cultivars (Arbosana, Arbequina, Koroneiki and Sorany) to devise a comprehensive shoot induction and proliferation protocol of olive media supplemented with various combinations of growth re...

Various transcriptome studies have remained useful in unraveling the complexity of molecular pathways regulating the oil biochemical contents and fruit characteristics of agronomic value in olive. Genes networks associated with plant architect and abiotic stress tolerance have been constructed due to robust genomic data generated by the tools of ge...

Soil solarization or covering proved to be a good method for soil water conservation and leads to a peter yield and controls soil pests & grasses. Objective: Therefore, an experiment was conducted at the Agricultural Research Station of King Abdulaziz University at Hada Al-Sham, 120 km northeast of Jeddah City, to study the effect of soil solarizat...

This experiment was conducted at the Agricultural Re- search Station of King Abdulaziz University at Hada Al- Sham Center in Makkah Al-Mokarramah Region, during two seasons (1997 and 1998) using two varieties of cabbage (Copenhagen V1 and Brunswick V2). The experiment aimed to study the effects of four nitrogen levels (0, 100, 200, and 300 Kg N/ ha...

Research was conducted during two consecutive seasons 2002/2003 and 2003/2004 to examine the effect of wounding treat- ments alone or in combination with IBA treatments on rooting response. Auxin treatments showed significant increase in root num- ber, length, fresh and dry weight for both wounded and non wounded cuttings treated with IBA at the 15...

An experiment was conducted to study the in vitro shoot proliferation of dormant woody stems of Ligustrum vulgare and Lunicera maackii placed in a solution containing either silver thiosulfate (STS) or the combination treatment of GA3+STS. The influence of BA or TDZ included in the forcing solution or the culture medium on woody plant performance i...

Experiments were conducted to determine the effects of Parent stock plant size (50 vs 75 cm height), cutting position (primary vs secondary branch), 5-7 cm and 3-5 cm cutting length, and the use of different levels IBA 0, 1500, 3000, 6000 and 9000 ppm on rooting responses of Pinus maximartinezii by using stem cuttings. Results showed that rooting a...

Research was conducted in February 1999 to study the effects of including silver thiosulfate (STS), gibberellic acid (GA3), or both, in the forcing solution on rooting of softwood cuttings produced by forced dormant stems of Cornus alba and Euonymus alatus. The forcing treatments employed were the basic forcing solution (200 mg 8-HQC/l and 2% sucro...

A series of experiments was conducted to further modify the forcing solution technology in order to expedite the propagation of woody plants such as Cornus alba, Euonymus alatus, Ligustrum vulgare, Lonicera maackii and Spiraea canescens. Silver thiosulfate (STS) in the forcing solution hastened bud break, increased per cent bud break and enhanced s...

Research was conducted in Feb. 1999 to study the effects of including silver thiosulfate (STS), gibberellic acid (GA 3 ), or both in the forcing solution on rooting of softwood cuttings produced by forced dormant woody plant species. The cuttings were dipped for 10 s in 2000 ppm indole-3-acetic acid (IAA) or 2000 ppm indolebutyric acid (IBA). High...

Research was conducted to further modify the forcing solution system in order to expedite the propagation of woody plants, such as Spiraea canescens, Lonicera maakii , and Cornus alba . Time of immersion in solutions containing 5 mM silver thiosulfate (STS) was compared with the basic forcing solution reported by Yang and Read (1989), a solution co...
