The culture of grass inflorescences has been attempted for three different reasons: (a) to induce somatic embryogenesis (Sharma et al. 1984; Vasil 1985; Rhodes et al. 1986; Pareddy and Petolino 1990); (b) to study the factors responsible for spikelet

Maturation of maize pollen was obtained in male reproductive structures cultured in vitro. Immature tassels containing microspores at the mid-uninucleate to late-binucleate stage of development were excised and spikelets, anthers, and/or isolated mic

In vitro procedures for crop improvement have most typically involved dedifferentiation and abnormal proliferation of somatic cells followed by plant regeneration via either organogenesis or embryogenesis. Even when immature reproductive structures h

In the study of cell organization in a maize meristem, direct viewing of confocal optical sections in 3D (by means of 3D projection of the volumetric data set, Figure 1) becomes very difficult and confusing because of the large number of nucleus invo

The role and metabolism of sucrose in cultured tassels of Zea mays cv. Oh43 were investigated. Although cultured tassels required 0.3 M (10% w/v) sucrose for "normal" development, they consumed less than 50% of it by day 21 of culture. The substituti

The effects of amino acids on spikelet development in in vitro cultured tassels of Zea mays inbred line Oh43 were studied. Single amino acids had differential effects on growth and differentiation of cultured tassels. While a few amino acids (arginin

The medium and conditions which permit in vitro culture of immature tassels of Zea mays cv. Oh43 are reported. Final fresh weight, total number of spikelets and the number of normal spikelets were enhanced by optimal concentrations of sucrose (0.3 M)

Tassel culture of maize (L.) to obtain normal development has significant potential for both basic and applied research studies. However, potential use of this technique for genetic manipulations has been limited by genotype specificity. This study w

Anthers from a highly androgenic genotype of maize (139/39-02), when cultured in a modified, liquid YP medium, dehisced within 2–7 days resulting in a stationary suspension of microspores. After 12–15 days, the microspore suspension was found to

In contrast to plant tissue culture procedures which promote callus proliferation, cell suspensions and plant propagation, the culture of flower and inflorescence primordia can be designed to favor normal growth and differentiation. The technique has
