Abstract

Aphelandra sinclairiana Nees. and A. aurantiaca (Scheidw.) Lindl. ‘Roezlii’ were self-compatible, while Aphelandra squamosa Nees. ‘Dania’ was pseudo-self-compatible and occasionally yielded seed after self pollination. Attempts at producing interspecific hybrids were unsuccessful; most pollen tubes failed to traverse more than 10% of the style. Bud pollination and pollination of amputated styles were unsuccessful.

Abstract

Spathiphyllum‘ Mauna Loa’ seedlings flowered after a single spray of gibberellic acid (GA3) at 250, 500 or 1000 mg/liter. Significantly more inflorescences per plant were produced at the 1000 mg/liter treatment. Severe flower distortion, consisting of either curved peduncles or spathes with extra appendages, was observed on 15% of all GA3-treated plants.

Abstract

Aglaonema commutatum Schott ‘Treubii’ sprayed once with 100, 200, or 400 mg/liter gibberellic acid (GA3) in December flowered about 143 days after treatment. Significantly more flowers were produced at the 400-mg/liter treatment than at 100 or 200 mg/liter.

Abstract. Aglaonema crispum (Pitcher & manda) Nicols., A. pictum (Roxb.) Kunth and A. commutatum Schott ‘Treubii’ inflorescences pollinated at high (100%) relative humidity (RH) showed excellent in vivo pollen germination. Inflorescences pollinated at low (40% to 50%) RH revealed significantly less germination than those pollinated at high RH. Pollen exposed to low RH for 4 hr before pollination did not germinate.

Abstract

Foliar sprays of BA were successfully used to increase basal shoot production on a nonbranching Dieffenbachia hybrid. Three foliar sprays at 250 mg·liter−1 stimulated significantly more shoot development than one or two sprays. Treatment at 500 or 750 mg·liter−1 BA yielded more shoots than 250 mg·liter−1. New shoots were visible four weeks after treatment and developed normally. Chemical names used: N- (phenyhnethyl)-1H-purin-6-amine (BA).

Abstract

Dieffenbachia maculata (Lodd.) G. Don ‘Perfection’ inflorescences pollinated at high (100%) relative humidity (RH) revealed excellent in vivo pollen germination and produced seed. Those pollinated at low (40-50%) RH showed almost no pollen germination and did not set seed. Anthers dehisced pollen better at high RH than at low.
