The simultaneous occurrence of a peak in auxin concentration and a strong increase in cell diameter in the carpel of seeded fruits suggest that indole‐3‐acetic acid stimulates a major increase in cell diameter at later stages of fruit growth. However, according to Silva (2002), when combined with other characteristics, the water content is considered an important index for the maturation process and is suggested as a reference for indicating the physiological condition of the seeds. A period of very rapid cell division, but very little increase in fruit size (stage I), is followed by a period of rapid increase in size as small, newly differentiated, dense cells develop vacuoles and assume their roles as specific tissues (stage II).

The possible causes of physiological fruit abscission (June drop) in peach (Prunus persica), which occurs between late Stage 2 and early Stage 3, was investigated for two years. [ Links ], ALVES, E. U. Maturação de sementes de sabiá (Mimosa caesalpiniifolia Benth.). O diâmetro, comprimento e massa seca dos frutos de Physalis peruviana foram maiores com maior maturidade fisiológica. Both gross (large muscle movements) and fine (small movements) motor skills contribute to physical development, and children often learn a set of skills by a certain age. << An exocarp will develop a cuticle and may exhibit a variety of morphological features such as coarse hairs (kiwifruit) or fine hairs (peach).
