详情

The banana plant is a large perennial herb with leaf sheaths that form trunk-like pseudostems. The plant has 8 - *2 leaves that are up to 9 ft long and 2 ft wide. Root development may be extensive in loose soil in some cases up to *0 ft laterally. Other plant descriptions vary, it depends on the variety.
Flower development is initiated from the true stem underground (corm) 9 - *2 months after planting. The inflorescence (flower stalk) grows through the center of the pseudostem. Flowers develop in clusters and spiral around the main axis. In most cultivars, the female flowers are followed by a few "hands" of neuter flowers that have aborted ovaries and stamens. The neuter flowers are followed at the terminal ends by male flowers enclosed in bracts. The male flowers have functional stamens but aborted ovaries.
Fruits mature in about *0 - *0 days after flowers first appear. Each bunch of fruits consists of variable numbers of "hands" along a central stem. Each "hand" consists of two transverse rows of fruits ("fingers").
The fruit quality is determined by size (finger length and thickness), evenness of ripening, freedom from blemishes and defects, and the arrangement of the clusters. Quality standards may differ in various markets.
