The involvement of exogenous calcium ions in the regulation of pollen tube formation has been investigated in Haemanthus albiflos L. and Oenothera biennis L. by following the changes that occur in pollen germination, tube growth, and 4SCa 2+ uptake and distribution upon application of Verapamil (an

A number of components isolated from styles of P. avium cv. Napoleon ($3S4) have been tested for their capacity to influence in vitro growth of pollen tubes from fresh and stored pollen (cv. Napoleon ($3S4)). An antigenic glycoprotein (Antigen S) is a potent inhibitor of in-vitro pollen tube growth,
The effects of canavanine, ~,y-diaminobutyrie acid, homoarginine and lathyrine on the germination of pollen and on in-vitro growth of pollen tubes were studied in the following species: Lathyrus niger, L. 8ilvestris, Vieia uni]nga, Pisum sativum and Citer arietinum. The effects of these non-protein
Cycloheximide, a potent inhibitor of protein synthesis, placed in styles of Lilium longiflorum at 10(-4) M in stigmatic exudate before, 6, or 12 hr after compatible or incompatible pollination retarded all pollen tube growth. An inhibitor of RNA synthesis, 6-methylpurine, placed in the style at 10(-
