Structure and devlopment of seeds and two types of fruits of Dimorphotheca sinuata have been investigated. The ovule is anatropous, unitegmic and tenuinucellate. The integument at the organised female gametophyte stage is distinguishable into three zones, (a) outer zone of compactly arranged ...
Here we describe the morphological characteristics of the fruits and seeds, and the development of seedlings. The multiple, indehiscent fruits are apocarpous, unattached to one another, with a fleshy pericarp, and the seeds are darkish brown and discoid in shape, with an ornamented, rugose ...
Developmental anatomy of seeds and fruits in Helichrysum bracteatum and Vicoa indica has been investigated. In H. bracteatum the mature seed coat is usually composed of 2 cell layers but in V. indica it is represented by crushed remains of the integumentary cells. Only the outermost layer of ...
The scope of this chapter is the development of the shoot meristem after it has changed from the vegetative to the reproductive state (a transformation which has been studied in detail in the preceding chapter) through the very last step, namely the ripening of the fruits and seeds. In this ...
Highly regulated catabolic activities take place in gerontoplasts, while resources are relocalized to seeds or perennial tissues. Chloroplasts emerge upon illumination (photomorphogenesis) [9]. Characterized by the presence of chlorophyll and a complex network of internal membranes, the thylakoids, ...
Fruit fresh and dry weight increased until 50 and 70 d after flowering, respectively. Growth in the first 21 d was due mainly to rind growth, and subsequent growth was due primarily to growth of pulp (arils and seeds). Accumulation of soluble solids and acids peaked 63 d after flowering,...
Dormancy and the Control of Germination Dormancy is the temporary failure of a seed to complete germination under favorable conditions. It allows for the dispersal of seeds in space and time. The... JD Bewley,KJ Bradford,HWM Hilhorst,... - Springer US 被引量: 1032发表: 2013年 Seeds: Physi...

However, the mechanism by which H2S affects the germination of seeds is still unclear. Tobacco (Nicotiana tabacum L.) is one of the most important economic crops and is extensively cultivated in the southern region of China. The aroma of tobacco is pleasing and it is widely used as an ...
