Experiments similar to that outlined above indicated that (1) the initiation of the stamens depends on the regulatory influence of the sepal and petal primordia, (2) the initiation of the petals depends on the regulatory influence of the sepal primordia, and (3) the initiation of the sepals depends on the regulatory influence of the lower plant body, all working in concert with the regulatory effects of the bud apical region The experiments described in this paper test popular hypotheses concerning the control of floral organogenesis. dia (-di ) the first recognizable, histologically differentiated stage in the development of an organ. The carpels, e.g., would emerge rarely if the primordial stamens were removed from a flower bud prior to carpel determination However, removal of either or both of the sepal or petal primordia had no such effect The initiation of the carpels depends on the regulatory influences of the primordial stamens and the bud apical region. in your mouth and 9 Embryonic taste bud primordia are specified as taste placodes. Struktur meristemoid yang bersifat kompeten untuk membentuk organ akhirnya terdeterminasi menjadi primordia organ. 166575 < Latin prmrdium, in pl. Specifically, the invention relates to molecules comprising a gibberellin activator or a gibberellin inhibitor operably linked to a promoter specific to a lateral organ primordium. dia (-di ) the first recognizable, histologically differentiated stage in the development of an organ. Flower buds of tobacco (Nicotiana tabacum), excised before organ primordia are present or, except for the sepals, determined, will continue normal development and produce all floral organs in a usual sequence when placed on a simple, defined medium lacking growth substances By surgically manipulating organ primordia, it was possible to infer the source of influences regulating the initiation of each type of organ. The tongue is a sensitive organ with multiple nerve endings. The invention relates to molecules for controlling plant growth and development.
