“…Furthermore, mepiquat chloride did not affect seed yield and its components. In contrast, Geneva et al [20] observed that prohexadione-Ca and mepiquat chloride in combination with fertilization increased both the number of flower heads and seed yield in milk thistle crops.…”

“…These results may be attributed to the fact that despite the reduction in plant height with MC treatments, the number of flower heads, 1000-seed weight, and chlorophyll content were not affected. In contrast, Geneva et al [20] observed that the application of plant growth retardants, such as mepiquat chloride and prohexadione-Ca increased the silymarin yield in milk thistle, mainly due to an increase in seed production. Moreover, Stancheva et al [21] reported that thidiazuron combined with foliar fertilizer increased silymarin content by approximately 10%.…”

Impact of Plant Density and Mepiquat Chloride on Growth, Yield, and Silymarin Content of Silybum marianum Grown under Mediterranean Semi-Arid Conditions

2019

Milk thistle (Silybum marianum (L.) Gaertn.) is a promising new crop in the Mediterranean region. Its seeds contain silymarin, a complex of flavonolignans, which is widely used in the pharmaceutical industry, mainly to produce dietary supplements. To meet the increasing demand for milk thistle, the production and productivity of milk thistle should also be optimized by employing adequate cultivation practices. In the present study, a two-year field experiment was conducted to assess the effects of plant density and a plant growth regulator on milk thistle crop growth, seed yield, and silymarin accumulation under Mediterranean semi-arid conditions. Our results showed that plant density had a significant impact on milk thistle crop growth and seed yield. The main crop characteristics, such as height, aboveground biomass, and seed yield were greatest when plant density was the highest. Increased plant density significantly reduced the silymarin content only in 2018. In contrast, mepiquat chloride (MC) treatment did not affect the following traits: plant biomass, relative chlorophyll content, silymarin content, and production. Nevertheless, mepiquat chloride reduced the plant height by 7.9-14.8%, depending on the application rates and growth conditions. Moreover, the impact of climatic conditions on milk thistle production and quality was significant, since the lowest values of silymarin content and seed yield were recorded in the year with drought conditions during the period from March to May.

“…Like other plants, milk thistly acquires and assimilates nutrients in requisite quantities for better growth and yield (Geneva et al 2007;Školníková et al 2019). Some nutrients are both structurally and functionally important (e.g., nitrogen, phosphorous, calcium and sulfur), while others (e.g., K and Ca) are not part of plant structure but are required for physiological processes in soluble form (Taiz et al 2015).…”

Salinity stress negatively affects key physiological phenomena in plants while plants show great variability and respond differentially for tolerance to salt stress. Usually, nutrients imbalances affect specific plant tissues and physiological processes which are requisite for normal plant growth and development. The aim of this two-year (2017 and 2018) simulated field study was to investigate phenotypic plasticity for growth, relative leaf water content (RLWC) and nutrient status in milk thistle [Silybum marianum (L.) Gaertn.] ecotypes and the potential role of soil supplementation with pre-optimized levels of plant growth promoters (PGPs) in modulating these attributes under control and salinity (12 dS/m) stress. Four ecotypes of milk thistle were collected from three ecologically distinct zones including Faisalabad (FSD) and Kalar Kahar (KK) – semi-arid zone, Gujranwala (GUJ) – hot semi-arid zone and Quetta (QTA) – cool semi-arid zone. The studied nutrients were nitrate-N, phosphate-P, sulfate-S, sodium (Na), potassium (K) and calcium (Ca). The soil supplemented PGPs, applied with irrigation water, were ascorbic acid (AsA), thiourea (TU) and moringa leaf extract (MLE) at 250 μM, 500 μM and 3%, respectively of soil moisture content at field capacity. Results indicated that soil supplementation of PGPs in the field conditions is a feasible approach for enhancing nutrient uptake of milk thistle ecotypes under salt stress, while the effect of salinity stress restricted the uptake of the studied nutrients and caused their imbalance. Although the salinity stress reduced shoot and root dry matter, RLWC and restricted the uptake of these nutrients irrespective of ecotypes, the levels of nitrate-N, phosphate-P, K, sulfate-S, Ca, and RWC contents increased more with the soil supplementation of AsA followed by MLE as compared to other soil supplements in both the study years. Among the ecotypes, QTA followed by KK and FSD ecotypes gained more dry weight with greater leaf RWC and higher tissue nutrient contents due to PGPs under salt stress. The principal component analysis and correlation data revealed the existence of distinct phenotypic plasticity in the milk thistle ecotypes for nutrient acquisition with soil supplementation of PGPs under salinity stress. To conclude, ecotypes from QTA and KK were more promising than the others while AsA and MLE were better soil supplements in improving shoot and root nutrients under salt stress. © 2021 Friends Science Publishers

A field experiment was conducted during two successive seasons of Medicinal Plants (ARCMP) affiliated to the National Organization for Drug Control And Research (NODCAR). Present work aimed to study the effect of inoculation Pimpinella anisum L. seeds with arbuscular mycorrhizal fungi (my) and/or microbein (mi) and/or foliar spray plants with thidiazuran (TDZ) combine with chemical fertilizer at half or full dose of NPK on the volume of the volatile oil of anise seeds, physiochemical investigation (Specific gravity of each essential oil and Refractive index of each essential oil), Compositional analysis by GLC of each essential oil percentage (linalol, estragole, alpha-terpenol, cis-anethole, trans-anethol and anisaldhyde) , total phenolic content and total flavonoid content of dry seeds. The results showed that inoculation anise (Pimpinella anisum L.) seeds with mixture of mycorrhizal and microbein at full dose of NPK gave the highest yield of the volatile oil of anise seeds , total phenolic content and total flavonoid content of dry seeds. While treated plants with biofertilizer (mycorrhizal and/or microbein) /or sprayed plants with TDZ combine biofertilizer at half or full dose of NPK didn't have any significant effect on physiochemical investigation and compositional analysis of volatile oil by GLC as compared to the control.
