Unformatted text preview: edonary laterals grow at soil level. The main stem can be upright or prostrate and from 12 to 35 cm long or may exceed 1m in runner types. The early vegetative growth stage is mainly concerned with mainstem elongation and leaf production, whereas the formation of lateral branches dominates later growth. Mainstem leaves account for >50% of the leaf area of plants for the first 35 days, but at 90 days they account only for 10%. After flowering, dry matter accumulation is mainly in the reproductive structures. The growth and branching patterns differ between subspecies and botanical types. Subspecies hypogaea has alternating pairs of vegetative and reproductive nodes, while subspecies fastigiata has a sequential pattern of reproductive nodes. - TO ACCESS ALL THE 30 PAGES OF THIS CHAPTER, Visit: http://www.eolss.net/Eolss-sampleAllChapter.aspx Bibliography Boote, K.J.
