Nectary biology ofCucurbita pepo: ecophysiological aspects

Acta Botanica Neerlandica, 1996
SUMMARY Nectary structure, nectar secretion and composition and insect visits were studied in male and female flowers of Cucurbita pepo in which anthesis lasts only 6 hours. The nectaries of male and female flowers develop in the same way, with presecretory, secretory and postsecretory phases; the flowers are dimorphic with regard to the position ...

Different AT-rich satellite DNAs in Cucurbita pepo and Cucurbita maxima

Theoretical and Applied Genetics, 1986
The AT-rich highly repeated satellite DNA of Cucurbita pepo (zucchini) and Cucurbita maxima (pumpkin) were cloned and their DNA structure was investigated. DNA sequencing revealed that the repeat length of satellite DNA in Cucurbita pepo is 349-352 base pairs. The percentage of AT-base pairs is about 61%.

Do Cucurbita pepo Gourds Float Fishnets?

American Antiquity, 2004
Among the various pre-maize indigenous crops of eastern North America, Cucurbita pepo gourd is the most enigmatic.C. pepogourd remains have been found on mid-Holocene (8000–4000 B.P.) archaeological sites as far north and east as Maine. Their presumably extremely bitter flesh would have made the fruits inedible.

Tapetum development in Cucurbita pepo (Cucurbitaceae)

1993
The tapetal cell walls are of uniform thickness before prophase; from leptotene onwards, those of the inner tangential and the proximal half of the radial wall swell. At late tetrad stage the swollen walls disappear, only the outer (distal) tangential and the distal part of the contiguous radial walls persist until degeneration.

Characterization of esterases from Cucurbita pepo cv. “Eskandrani”

Bioresource Technology, 2008
Two of the six esterases identified in Cucurbita pepo cv. "Eskandrani" were purified to homogeneity using two chromatography steps: anion exchange and gel filtration. The molecular weights of C. pepo esterases EIc and EII were 50,000 +/- 1500 and 68,000 +/- 1900 Da from gel filtration and 47,000 and 66,000 Da from SDS/PAGE, respectively, suggesting a ...

2021
Aims. It is known that seed signs in comparison with vegetative bodies change more poorly. However stability of these signs from factors of environment is relative and when placing plants in new conditions of the environment they can be more subject to changes. Methods. Researches conducted in the conditions of 2005???2006 and 2008???2011.
