Die Praxis der Erziehungshilfen,sequent to the production of the first few flower primordia, the plant bolts due to increased internode elongation between the uppermost leaves and between flowers. Thus, the basal positions on the primary inflorescence shoot are occupied by a small number of cauline (stem) leaves and the apical posSUGAR 发表于 2025-3-23 18:28:59

The number of rosette leaves formed prior to the transition to flowering (leaf number) varies with growth conditions, with low growth temperatures and short days retarding the transition to flowering.

Thus, the vegetative meristem is apparently converted directly into an inflorescence meristem, which produces the primary inflorescence shoot. There appears to be no fundamental difference in organization between the two types of meristems and the d舞蹈编排 发表于 2025-3-24 18:51:20

Table 1 summarizes some of the landmark events and attempts to relate them to defined stages of flower development (Müller, 1961; Smyth et al.,1990). However, since the data on pollen development were amalgamated from several sources, it is likely that some描绘 发表于 2025-3-24 20:42:18

The central region of the septum consists of transmitting tissue, while the tissue at the margins of the septum is fused with and is similar in appearance to the tissue of the inner layer of the ovary wall (Okada et al., 1989).背信 发表于 2025-3-24 23:21:11

Successful pollination is the result of a series of events, including pollen contact, adhesion and attachment of pollen to the stigma, pollen hydration, pollen germination, pollen growth through the stigma, style, and ovary, and finally, fertilization of the ovule (Knox, 1984). Each of these
