Flower Bud Development in Greenhouse-Grown Cotton

The determination of cotton (Gossypium hirsutum L.) bud age in days relative to anthesis (DRA) is of value for studies of fiber differentiation. Bud age is easily judged at 1-d preanthesis (-1DRA) but is less discernible in younger buds. The objective of this study was to relate bud length to bud age relative to anthesis and to determine the effect of bud position on bud length. 'Stoneville 506' cotton was grown in a greenhouse in 4-L pots of potting mixture. Data were taken from 48 plants planted 14 Mar. 1991 [...]
