Abstract

Roselle (Hibiscus sabdariffa L.) is an annual herbaceous subshrub believed to be indigenous from India to Malaysia (2). It is a short-day plant (1), and when grown at the latitude of Israel (32°N), the earliest possible date of flower initiation is 5 Aug. Preliminary studies have indicated that vegetative and reproductive growth ceases in autumn (5), which may be due to exposure to low night temperatures. The objective of this study was to determine the sensitivity of roselle to chilling at different growth stages.

Abstract

Pot plants of calamondin (Citrus madurensis Lour.) were dark-stored for 2 weeks at 10° or 20°C. There was considerable leaf and fruit abscission in plants stored at 20°. Plants stored in the dark for 2 weeks at 12° were of excellent quality and leaf and fruit drop was negligible during storage. These plants continued to flourish in a simulated home environment. Horizontal placement of plants during storage increased packing density by 50% without reducing plant quality, compared to plants packed in a vertical position.

Abstract

Three clones of Ficus benjamina L. and one clone of Ficus retusa L. foliage pot plants were raised under 3 different light intensities. Variations in the morphological development of the clones in response to light intensity were recorded. Leaf abscission from these plants was followed at the end of 2 weeks of dark storage, and during a subsequent period of one month in a simulated home environment. In unstored plants, only low levels of leaf drop were observed. Leaf abscission was stimulated strongly during dark storage and in subsequent indoor environment. The degree of dark storage-promoted leaf abscission, and the response pattern to light intensity during the production phase, with regard to leaf drop during simulated home conditions, showed a clear clone-dependent specificity. It is concluded that the genetic background is a major factor affecting storability and subsequent performance under simulated home conditions.
