Aim: Parenting practices can reduce how much television (TV) children watch. This study evaluated the longitudinal association between maternal regulation of TV content and the amount of TV watched by low-income ethnic minority children.
Methods: This was a secondary data analysis of the Welfare, Children & Families: A Three City Study. Data were used from ethnic minority mothers with a child from birth to 4 years old, collected over two waves approximately 16 months apart. The dependent variable was the amount of TV watched by the child (wave two). The main independent variable was the maternal regulation of TV content (wave one). Using multiple linear regression, we evaluated the relationship between maternal regulation of TV content and the amount of TV watched by the child, adjusting for covariates.
Results: Of the 835 mothers, 71% were high content regulators and 8% reported no content regulation. Children whose mothers reported no regulation watched more TV approximately 16 months later than those whose mothers reported high regulation of content (β = 0.91, 95% CI: 0.09-1.73).
Conclusion: Our findings suggest that regulating content influences viewing amounts in young children approximately 16 months later. Interventions focused on heightening parental regulation of content may improve content and diminish viewing amounts.

(TYLCV) poses a significant threat to tomato production, leading to severe yield losses. The current control strategies primarily rely on the use of pesticides, which are often nonselective and costly. Therefore, there is an urgent need to identify more environmentally friendly alternatives.

Melatonin (MT) is a crucial hormone that controls and positively regulates plant growth under abiotic stress, but the biochemical and physiological processes of the combination of melatonin seed initiation and exogenous spray treatments and their effects on maize germination and seedling salt tolerance are not well understood. Consequently, in this research, we utilized the maize cultivars Zhengdan 958 (ZD958) and Demeiya 1 (DMY1), which are extensively marketed in northeastern China's high-latitude cold regions, to reveal the modulating effects of melatonin on maize salinity tolerance by determining the impacts of varying concentrations of melatonin on maize seedling growth characteristics, osmoregulation, antioxidant systems, and gene expression. The findings revealed that salt stress (100 mM NaCl) significantly inhibited maize seed germination and seedling development, which resulted in significant increases in the HO and O content and decreases in the antioxidant enzyme activity and photosynthetic pigment content in maize seedlings.

Optimizing nitrogen (N) sources has the potential to improve wheat tillering, nitrogen use efficiency (NUE), and grain yield, yet the underlying mechanisms remain unclear. This study hypothesizes that combining specific N sources can increase zeatin riboside + zeatin (ZR + ZT) content in tiller nodes and maintain a higher ZR + ZT/gibberellin A7 (GA) ratio, thereby promoting tiller development, enhancing NUE, and increasing yield. The effects of N source treatments on two wheat cultivars, the multi-spike Shannong 28 (SN28) and the large-spike Tainong 18 (TN18), were investigated.

Carotenoids, the bright yellow, orange, and red pigments of many fruits and vegetables, are essential components of the human diet as bioactive compounds not synthesized in animals. As a staple crop potato has the potential to deliver substantial amounts of these nutraceuticals despite their lower concentration in tubers compared to edible organs of other plant species. Even small gains in tuber carotenoid levels could have a significant impact on the nutritional value of potatoes.

(Shen) (Hemiptera: Cicadellidae) is a devastating insect pest species of , significantly affecting the yield and quality of tea. Due to growing concerns over the irrational use of insecticides and associated food safety, it is crucial to better understand the innate resistance mechanism of tea trees to . This study aims to explore the responses of tea trees to different levels of infestation.
