Graphic Display of Quantitative and Qualitative Character Associations in Cut Roses1

I. B. McLean, H. P. Rasmussen

Abstract

Abstract Difficulty is frequently experienced in displaying associations of quantitative characters such as flower weight and vaselife with qualitative characters such as flower shape, petal attitude, color, and leaf damage in cut roses ( Rosa hybrida L.) A scatter diagram technique which accommodates 2 quantitative and up to 12 qualitative characters applied to experiments on rose cultivars and floral preservatives revealed qualitative associations with increased vaselife and flower fresh weight in response to the use of various preservative solutions.
