Published: December 2002

Four new steroidal saponins, anguiviosides III (1), XI (2), XV (3), and XVI (4), were isolated and characterized from the fruits of Solanum anguivi. Their structures were elucidated on the basis of spectroscopic analysis. The occurrence of the cholestane glycosides 3 and 4 is considered from a biogenetic point of view.

<b>Background and Objective:</b> Prolonged utilization of chemical fertilizers can harm the soil and disturb the equilibrium of nutrients, resulting in a decline in cherry tomato yield. To enhance the growth of cherry tomato plants, it is necessary to add organic chemicals. The research aimed to determine the best elicitor biosaka concentration to apply to evoke the plant growth of cherry tomatoes (<i>Solanum lycopersicum</i> L.

Comparative transcriptome analysis and heterologous overexpression indicate that the ZjZOG gene may positively regulate the size of jujube fruit.

Henan Province Key Laboratory of Germplasm Innovation and Utilization of Eco- economic Woody Plant, Pingdingshan University, Pingdingshan, Henan, 467000, China.

Background: Fruit size is a crucial economic trait that impacts the quality of jujube (Ziziphus jujuba), however, research in this area remains limited. This study utilized two jujube cultivars with similar genetic backgrounds but differing fruit sizes to investigate the regulatory mechanisms affecting fruit size through cytological observations, transcriptome sequencing, and heterologous overexpression.

Results: The findings reveal that variations in mesocarp cell numbers during early fruit development significantly influence final fruit size.

Background: Fresh vegetables are commodities that have a high tendency to deteriorate after harvest, causing significant losses in economic and environmental costs associated with plant food loss. Therefore, this study was carried out to evaluate the effects of both un-irradiated (UISA) and irradiated sodium alginate (ISA) as an edible coating for preserving cherry tomato fruits under storage conditions. The FTIR, XRD, TGA, SEM, and TEM were used to characterize the UISA and ISA (25, 50, 75, and 100 kGy), which demonstrated that the alginate polymer was degraded and low molecular-weight polysaccharides were formed as a result of irradiation, particularly with the 100 kGy dose level.

The Effect of Biochar on Tomato () Cultivar Micro-Tom Grown under Continuous Light.

Unlabelled: Continuous lighting (CL) has the potential to increase crop yield in greenhouse production. Tomato plants, however, when exposed to CL develop inter-vascular chlorosis, a leaf injury which causes a reduction in chlorophyll content and necrosis. The application of biochar can reduce physiological stress in plants, we examine if biochar also reduces necrosis in tomatoes when grown under CL.

Objective: To analyze the nutritional content of Shanxi's main vegetables and fruits.

Methods: According to the national food safety standards, the nutritional content of 25 vegetables and 38 fruits produced in Shanxi Province from 2018 to 2022 were evaluated for their energy, protein, fat, carbohydrates, vitamins, and minerals.

Results: The contents of energy and carbohydrate of the vegetable samples from high to low were allium, solanum and tender stems, leaves and cauliflower, respectively, The contents of protein from high to low were allium, tender stems, leaves, cauliflower and solanum; The contents of carotene, vitamin B_1, vitamin B_2 and vitamin E in solanaceous vegetables were the highest, and the contents of vitamin C were the tender stems, leaves and cauliflower vegetables.
