“…It is believed that the semi-domesticated Solanum distichum Schumach and Thonn is claimed to have contributed to the domestication of Solanum aethiopicum from the wild Solanum anguivi Lam [19]. Cultivars of Solanum aethiopicum can be categorized into flour groups: Shum, Kumba, Aculeatum, and Gilo Group [20,21,22]. The Kumba and Gilo cultivars are grown for their fruit, whilst Shum is grown for its leaves [23].…”

“…When the fruits are in the commercial stage (physiologically immature), they might be white, green, or even purple in colour. Additionally, the fruit turns red or reddish-orange when it achieves full maturity, a colour change linked to a high carotene content [28,29,22]. The fruit is categorized as a berry since it has a firm firmness, a vibrant green calyx, and numerous tiny delicate seeds [30,31,14]; the kidney-shaped seeds have a diameter of 2-3.5 mm [26].…”

Northeastern region of India is endowed with variety of local vegetables that are highly nutritious and health-promoting. One of which is Solanum aethiopicum L which has a bountiful source of nutrients and bioactive chemicals. It has several pharmacological benefits and are used in indigenous medicine to treat various conditions. Nonetheless, the crop is highly perishable with a short shelf life (35days) which significantly contributes to postharvest losses. Techniques used to extend the shelf life of the crop are freezing, drying and refrigeration. The crop can be stored at low temperatures about 10-12oC. Fruits kept in perforated polyethylene bags had the longest shelf life. Important materials include polyethylene, polypropylene, and polystyrene are commonly used and coating can be applied to increase the crop’s shelf life. The crop has a huge potential in making value added products like pickles, dehydrated products and many more. However, concerns related to postharvest and production of the crop have not received equal attention due to scant research with the crop being neglected and underutilized due to lack of awareness and limited market. Considering the crop offers many advantages, popularization of the crop is essential but adapting to the bitter taste and flavor of the fruit could be challenging for the consumers. Consumer attitudes, views, and willingness to pay for products that have undergone particular post-harvest procedures require further investigation. Proper cultivation techniques, processing, value addition and marketing are required to surpass these hurdles.

“…Germination cannot be taken place below and above these extreme temperatures. Botey et al (2021) reported low germination of Solanum aethiopicum L. seeds at lower (15  C) and higher (35  C) temperatures. Gibberellins promote germination.…”

Background: The initial stage of plants and sunlight as the energy source are very critical for plants. A boost of biochemical reactions given by concentrating solar energy at the initial stage of plants may continue accelerated growth and yield. Rice is a high-demand crop. Therefore, in this research study, the germination of rice seeds was studied under different radiation levels using a spherical solar concentrator (SSC). Methods: The germination percentage of rice seeds was observed under different radiation levels. Experimental setup 1 consisted of 60 cm below the SSC (SSC 60 cm) and open environment (OE) whereas Experimental setup 2 consisted of 45 cm below the SSC (SSC 45 cm) and OE. Result: SSC (60 cm) and SSC (45 cm) manifested 1.2 and 1.5 times higher solar energy than the OE, respectively. In experimental setup 1, it was observed germination percentages of 65.2 and 58.8 in SSC (60 cm) and OE, respectively whereas, in the experimental setup 2, 86.9 and 77.5 in SSC (45 cm) and OE, respectively. It can be assumed that plants grown under SSC during the nursery stage, reach the fullest potential at maturity as a result of increased flux density and lower soil temperature under the SSC.

The final germination expressed as a percentage alone is unsatisfactory for reporting results related to the germination capacity of a seed lot. Information on other quantitative variables are thus important to judge the agronomic value of a seed lot. To evaluate the seed germination characteristics of the African eggplant, seeds were extracted from fruits harvested at different maturity stages produced under both tropical and temperate oceanic climates. The seed germination behaviour was assessed by germinability, germination rate, homogeneity and synchrony of the seed lots. The data for each environment was analyzed separately in a two-way ANOVA constituting harvesting maturity stages and cultivars as factors. The results showed that seed germinability increased with maturation and maximum when fruits were harvested 76 DAA under both climates. Seeds harvested precociously failed to germinate regardless of the production environment. All seed quantitative variables measured were positively related to the final seed germinability. The seed germination rates measurements significantly increased with seed maturity, indicating seed vigour and final germinability improves with maturation. Coefficient of variation of germination time (CVt) was a good measure of uniformity in seed germination. The results further showed a strong and positive correlation with seed germination parameters such as GI, GV, MDG, CVG and U to final germination. It is recommended that for maximum seed quality, fruits should be harvested at 76 DAA. It is further suggested that seed germination results should be enriched by measuring other quantitative parameters as it communicates different aspects of the germination process.
