This study examined the effects of storage temperature and pre-chilling on the germination of the seeds of Solanum macrocarpon – which according to literature has a seed viability of 63.33%. In our study, the seeds were sown in dry Petri dishes and placed in the refrigerator set at 4 °C for 1, 3, 5, 7 and 10 days. Another set of seeds was placed in incubators set at 25, 35 and 45 °C for 40 days before the germination experiment was carried out on a laboratory workbench. Results from the study revealed that while storage temperature had a significant effect on that the germination of seeds of this plant, pre-chilling of seeds and incubator treatments generally reduced seed germination. Thus seed germination in this plant is temperature dependent.

Fruits producing medicinal plants are particularly desirable, the seeds produced are considered as waste after the fruits are consumed. This study assessed the nutritional constituents of some fruits seeds by assessing the proximate, minerals and vitamins present in the seeds of Citrullus lanatus (Water melon), Malus pumila (Apple), Annona muricata (Sour sap), Persea americana (Avocado), Terminalia catappa (Almond fruit), and Carica papaya (Pawpaw). The proximate analysis, mineral and vitamin composition of the selected medicinal fruit seeds were investigated using the standard method of analysis. On the proximate composition, protein content ranged from 15.21-34.70%, crude fat: 13.82-33.15%, crude fibre: 6.96-21.71%, ash content: 2.62-5.90%, moisture content: 7.81-20.72% and carbohydrate: 12.19-26.58%; for mineral content, Sodium ranged from 26.2-832 mg/kg, Potassium: 571-4862 mg/kg, Calcium: 194-2070 mg/kg, Magnesium: 28-862 mg/kg, Phosphorus: 104-1070 mg/kg, Iron: 2.53-60.00 mg/kg, Manganese: 2.73-240 mg/kg, Copper: 1.64-73.00 mg/kg and Zinc: 3.42-84.00 mg/kg, while for vitamins, vitamin C (Ascorbic acid) content ranged from 1.26-23.54 mg/100g, vitamin E content ranged from 0.70-1.57 mg/100g; vitamin A (β-carotene) content ranged from not detected-5.61 mg/100g, while vitamin B content ranged from 0.02 mg/100g-2.67 mg/100g. The fruits’ seeds show a considerable amount of vital nutritional chemicals which makes them as good as the fruits and could serve as nutraceutical remedy.

Using physiologically active, complex, polyfunctional, multicomponent (nano) systems – (nano) chips in the pre-sowing rice treatment (nano) technology allows precise seeding; enhancing field seed germination; reducing plant morbidity rate considerably or even deleting disease incidents; increasing plant adaptability to unfavorable environmental conditions; expanding crop yield; improving products quality by not using toxic chemical means of plant protection; intensifying competitive ability of agricultural products as well as assuring environmental safety in crop cultivation regions. Nutrition micro- and mesoelements, as also intense activity plant growth regulators and other physiologically active substances, depending on the crop variety, cultivation conditions and possible risks, can be added to such pre-sowing treatment (nano) technology.
