Female flower--pollen tube entering the stigma by stylar
epidermal cells or intercellular spaces, present (0), absent (1)
Pericarp at the lateral side of fruit was removed from stylar
end to stem end by knife and flesh firmness at center of the biggest segment was measured by texture analyzer TA-XT 2I with 2 mm spherical plunger in 5 mm distance depth and 1.0mm/s test speed, expressed as Newton force.
The secretions present in the stigma and the central canal in the stigmatic and stylar
transmitting tissue, took on a deep red coloration after staining with safranin, and they reacted strongly to PAS (see Figure 4O).
Digital Clarity is a trading name of Stylar
Despite this diversity, Robbrecht (1988) pointed out the presence of three reproductive strategies common in Rubiaceae-distyly, morphologically characterized by the presence of two inter-compatible floral morphs, which is generally observed in species of Rubioideae (Barrett, 1992); stylar
pollen presentation involving protandry and pollen presentation in the style which is generally recorded in Ixoroideae (De Block and Igerscheim, 2001; Nilsson et al., 1990) and the occurrence of unisexual flowers in certain species almost restricted to Theligoneae and Anthospermae (Robbrecht, 1988).
Likewise, when looking into the matrix for the combinations of 'end' with other terms, examples such as 'end table' and 'stylar
end' are found.
includes about 1250 species of cosmopolitan distribution; it was distinguished principally by its truncate, penicillate stylar
tips, separated stigmatic lines, and the obtuse or rounded anther base with a balusterform filament collar.
1.5 mm long altogether, the stipe shorter than to nearly as long as the sharply trigonous body, the stylar
end slender elongate, slightly broadening and scaberulous-papillose distally; achene surface pale, minutely cancellate-punctate, the 3 edges smooth, wirelike, glassy.
This is a minimum estimate of the number of transitions in mating systems in the family: we based our inferences on experimental reports for some species, anecdotal reports for others, and certain assumptions (i.e., that species with stylar
movements that ensure self-pollination, or that possess cleistogamous flowers, are in fact self-compatible; and that dioecious species are self-incompatible).
3 mm, entire, glabrous, green; petals spatulate, apex broadly acute, 23-24 x 7-8 mm, very narrow toward base, connate at base for 2-2.5 mm in a common tube with the filaments and style, suberect to subspreading at anthesis, distinctly exceeding the stamens, white, without any distinct callosities; filaments white, terete, the antesepalous ones 14-16 mm long, the antepetalous ones 13-14 mm long, both adnate for 2-2.5 mm in a common tube with petals and style; anthers 2-3 mm long, fixed at 1/3 of its length above the base, base distinctly setaceous-sagittate, apex obtuse; pollen narrowly ellipsoid, sulcate, exine perforate to insulate, muri thicked; stigma conduplicate, white, stylar
lobes terete, suberect, ca.
A supergene complex has been proposed by Sharma and Boyes (1961), consisting of five subgenes corresponding to stylar
incompatibility, pollen incompatibility, style length, pollen size, and stamen height.
