One hectare of plants can produce 2.5 tons of seed. [10] The plant forms a fleshy tap root that is used as a storage and overwintering structure. [12] The central tap root can weigh up to 72 kg (159 lb). A four-year-old root grown under cultivation can reach a fresh weight of 45 kg (99 lb) and a length of 2.5 m (8.2 ft). [5]
A female squash bug lays bronze-colored oval eggs on the underside of the leaves of the squash family plants. Each squash bug female can lay as many as 18 eggs near the main vein on the leaf where ...
Ripe berries of S. nigrum. Solanum nigrum, the European black nightshade or simply black nightshade or blackberry nightshade, [1] is a species of flowering plant in the family Solanaceae, native to Eurasia and introduced in the Americas, Australasia, and South Africa.
The plant produces night blooming white flowers. The male flowers have long peduncles and the females have short ones with an ovary in the shape of the fruit. Sometimes the female flowers drop off without growing into a gourd due to the failure of pollination if there is no night pollinator (probably a kind of moth) in the garden.
It is a deciduous, dicot shrub growing 0.5–2.5 metres (1 + 1 ⁄ 2 –8 ft) tall. The bark is smooth and reddish grey in colour, the twigs glabrous. [9]The leaves are opposite, elliptic in shape, 6–10 centimetres (2 + 1 ⁄ 4 –4 in) long, unlobed or shallowly 3-lobed, jaggedly serrated, and turning red in autumn; their underside glabrous, especially along the veins.
Cucurbita palmata is a species of flowering plant in the squash family known by the common names coyote melon and coyote gourd. [1] [2] It is similar to Cucurbita californica, Cucurbita cordata, Cucurbita cylindrata, and Cucurbita digitata and all these species hybridize readily. [3] It was first identified by Sereno Watson in 1876. [1]
The yellow or orange flowers on a Cucurbita plant are of two types: female and male. The female flowers produce the fruit and the male flowers produce pollen . Many North and Central American species are visited by specialist bee pollinators , but other insects with more general feeding habits, such as honey bees , also visit.
The heavier the infestation, the greater the damage to the plant. Sometimes one plant or part of a plant can be heavily attacked while surrounding plants are untouched. [3] Besides the direct damage their feeding causes to the plant, these insects can act as vectors for cucurbit yellow vine disease caused by the bacterium Serratia marcescens ...
