this row in this table does not demonstrate SC because two plants were involved: a flower having undehisced anthers (short stamens) received pollen from a flower of a different plant of the same accession, resulting in a fruit.

Demonstration of lack of agamospermy / parthenocarpy:
In a pollinator-free greenhouse, after a flower had opened, anthers (prior to dehiscence) were removed;
flowers were unmanipulated (not pollinated by hand).

Evidence That Pseudogamy Is Not Happening

Interaccession Hybrids Appear Morphologically Intermediate: Hybridization of morphologically distinct collections/accessions of J. procumbens yields F1 plants that are morphologically intermediate between the parents.

For example, in 2013 I grew numerous F1 plants, the progeny of many different pairwise comparisons of morphologically distinct parental ecotypes. All of the F1 plants were morphologically intermediate, demonstrating genetic contribution from both the pollen parent and the ovule parent. Thus, psuedogamy (asexual seed production triggered by pollination but with no genetic contribution from the pollen) is not part of the reproductive biology of J. procumbens.

 

 

 

 

How Many Weeks from Pollination to Ripe fruit?

see details listed below as Tag 2014-6

between 5 and six weeks

Accession 842: a flower tagged for floral phenology observtations, see the table below for all data for tag 2014-32

between six and seven weeks

Of the six flowers that were tagged (not pollinated by hand, not emasculated) for observation on 28 & 29 September 2014 (see the 2014 tables of floral phenology, below), five produced ripe fruits containing numerous seeds, and one flower did not result in a ripe fruit. The fruits were harvested in November 2014 on or before 12 November

five to six weeks

 

 

 

 

 

 

 

 

 

 

 

Floral Phenology

Day 1

Day 2

summary of one flower's phenology

11 am. The flower was tagged. All but one flower of the inflorescence was carefully removed. Corolla has never been open (corolla is closed)

3:30 pm. Corolla partially open. Anthers undehisced. I can't determine whether or not nectar is present because corolla less than half open.

6:30 pm: corolla closed.

1:00 pm.

Stamens angle out strongly; anthers dehisced and 4 mm away from stigma. Nectar present.

10:50 am.

corolla-androecium dropped completely off prior to this observation.

Nearly no pollen on stigma.

Pistillate for one day,

hermaphroditic the next day,

Delayed Self-Pollination may have taken place: on 11 Oct the ovary was about 5 mm diameter, and 16 Oct about 7 mm diam, and 24 and 31 Oct about 7 to 8 mm;

fruit with attached calyx fell off between 31 Oct and 7 Nov, and so the tag was removed 7 Nov.

3:30 pm. Anthers undehisced. I can't determine whether or not nectar is present because corolla less than half open.

6:30 pm. corolla closed.

1:00 pm.

Stamens angle out strongly; anthers dehisced and 4 mm away from stigma. Nectar present.

10:50 am.

corolla-androecium abscised but had not completely fallen free. I handled the pot and the corolla androecium fell to the floor. The stigma looks to be about 10% covered with pollen.

Pistillate for one day,

hermaphroditic for next day.

Delayed Self-Pollination must have taken place because a partially developed fruit was seen 11 Oct, 16 Oct about 6 mm diam, and 24 and 31 Oct about 7 mm; on 12 Nov I found the tag but no fruit, the developing fruit had fallen off.

Summary

Flowers were open for three days. The flowers were pistillate the first two days (filaments short, anthers closed). The third day flowers became hermaphroditic, involving rapid filament elongation in the morning followed by anther dehiscence sometime between 8:00 and 11:00 am.
Delayed self-pollination:
Self-pollination was caused by the changing orientation of the stamens, bringing the anthers in contact with the stigmas.

Of the six flowers that were tagged (not pollinated by hand, not emasculated) for observation on 28 & 29 September 2014 (this table and the tables of the same color below), five produced ripe fruits containing numerous seeds, and one flower did not result in a ripe fruit. The fruits were harvested in November 2014 on or before 12 November, and thus it took five to six weeks for pollination-fertilization-ovary expansion-mature fruit.

8:00 am

The corolla-androecium must have abscised very recently because the corolla has not withered and has not yet dropped away (it is still on the flower, but is not physically attached), apparently held on because the stamens had come in tightly around the style. The most gentle pull (with forceps) resulted in the cor-androecium coming completely free, and I can see (with a 10X hand lens) pollen on the stigma.

Anthers have dehisced, filaments angle out strongly (proximal to distal, herkogamy); flower (including corolla position) is as shown in the flower at right in Figure 1.


4 pm:
Corolla closed in a very organized way (Fig. 16). The corolla tissue of the radii to the lobes have become centermost, while the corolla tissue of the radii to the lobules makes a double pleat. This configuration may cause the dehisced anthers to come in contact with the stigma, causing self-pollination.

Corolla-androecium abscised:

The stamens are epipetalous (attached to the corolla), so when the corolla drops, both corolla and androecium drop off together.

Pistillate for one day,

hermaphroditic for part of next day,

followed by

delayed self-pollination during day 2.

flower partially open, anthers undehisced

8:30 am:
Anthers dehising, filaments completely elongated, corolla more than planar as shown in the flower on the right in Fig. 1

10:15:
Anthers have completely dehisced, filaments (proximal to distal) angle out strongly (herkogamy).

2:45:
Corolla is relaxing compared to earlier today and so corolla is now planar; this brings the dehisced anthers toward the stigma because the stigma and the dehisced anthers are at the exact same height.

4:45:
Corolla is closed in a very organized way: the corolla tissue of the radii to the lobes have become centermost, while the corolla tissue of the radii to the lobules makes a double pleat. This configuration likely causes the dehisced anthers to come in contact with the stigma, causing self-pollination (Fig. 16).

8:45 am:

Corolla-androecium abscised;

the stamens epipetalous, so when the corolla drops, both corolla and androecium drop off together.

Pistillate for one day,

hermaphroditic for part of next day,

followed by

delayed self-pollination during day 2.

Anthers undehisced, filaments elongating, corolla planar, calxy reflexed

4 pm:
Anthers dehisced, filaments have elongated, anthers touching stigma

8:30 am:

Corolla-androecium abscised;

the stamens are epipetalous, so when the corolla drops off, both corolla and androecium drop off together.
