The flowers are complete having both the pistil and stamen. It is axillary and varies in colour. It grows up to 5 in (12.5 cm) wide with a rose or maroon eye (Morton, 1987). The petals usually last for only a day (Cooper, 1993). Haarer (1952) described the calyx as cup-shaped, longer than the epicalyx, and often purplish in colour.
The numerous flowers are borne in panicles 10 to 20 cm (3.9 to 7.9 in) in length. Each is around 6 to 7 cm (2.4 to 2.8 in) long and is white to blue in color. The petals are of different lengths, with the middle lower lobe being the longest. Both the corolla and calyx are covered in dense hairs [50, 51]. Geographical source Vitex negundo is native to tropical Eastern and Southern Africa and Asia.
The plants beforehand each had two larger leaves, three smaller leaves, and three leaves in bud form. The veins were lighter green while the leaves were darker green, and the leaves were smooth and tear-dropped shaped. One plant was speckled white while the others were green. For each plant we cut a square of parafilm; we stretched it out gently over the top of the pot, leaving just a little hole for the stem to come through, and stretched it to
Leaves are pinnate , and consist of 9-17 alternate oblong to lanceolate leaflets . The flowers are small (1 cm long), have purple to whitish blue colour, while its pods (2-3 cm) are flat, have an oblong to linear shape [5, 21], have a smooth surface , turn brown at maturity and contain 1-7 seeds [5, 21]. Lastly, seeds present a dark colour, a reniform shape and small size, with a diameter of about 2.5 mm and a thousand seeds weight of 6.2 g [21,
Abundant flowering flower panicles there is covered with a gray-hairy wrapping leaves. Pale yellow flowers are with a head lettuce shape and are tubular, external flowers have only pistils while the inner flowers are hermaphrodite. The smell of the plant is typically aromatic and intense,
If a fruit remains too long on the vine, it will turn spongy, sour yellow or orange and split open. Bitter gourd yield can vary depending on variety and crop management. Average marketable yields are 8-10 t/ha. Fruits of bitter gourd do not keep long and should be sold in the market immediate. Remove damaged and deformed fruits.
Besides, the system will trained with this model. The model will be tested. In the end, compare the both actual output and predicted output for accuracy. 3.4. 4 Performance The accuracy of the oil palm fresh fruit maturity classification system will be evaluated by using Mean Square Error (MSE) method.
