Inhibition of gamete formation by cycloheximide in pollen tubes of Impatients balsamina.

abstract：:The pistil of tobacco (Nicotiana tabacum L. cv. Wisconsin 38) is comprised of two fused carpels. The stigma is bilobed, papillose, and at maturity is covered with a sticky exudate. The style is solid. Both stigma and style are made up of four tissue elements-epidermis, cortex, vascular, and transmitting tissue. Transm...
