Anther Culture in Cucurbita Species

2021
Production of homozygous pure parental lines is the first stage of hybrid vegetable breeding. Unfortunately, producing pure lines takes a long time by classical breeding methods, especially in open-pollinated vegetable species, and this period can be up to 8-10 years.

Qualitative and Quantitative Differences in Carotenoid Composition among Cucurbita moschata, Cucurbita maxima, and Cucurbita pepo

Journal of Agricultural and Food Chemistry, 2007
Squashes and pumpkins are important dietary sources of carotenoids worldwide. The carotenoid composition has been determined, but reported data have been highly variable, both qualitatively and quantitatively. In the present work, the carotenoid composition of squashes and pumpkins currently marketed in Campinas, Brazil, were determined by HPLC-DAD ...

Adenosine triphosphatase in the phloem of Cucurbita

Planta, 1973
The distribution of adenosine triphosphatase (ATPase) activity in the phloem of petioles and minor veins of Cucurbita maxima has been studied using a lead phosphate precipitation procedure. ATPase activity was localized in sieve elements, companion cells and parenchyma cells.

An Acetocarmine Technic forCucurbita

Stain Technology, 1954
Staminate Cucurbita buds undergoing meiosis are fixed for 12–24 hours in a solution containing 3 parts of 95% alcohol, 1 part of acetocarmine to which iron acetate has been added, and a flake of rusted iron. After fixation the buds are washed in 95% alcohol and stored in 95% alcohol with the iron flake for 5-10 days.

Resistance in Cucurbita pepo and Cucurbita maxima germplasms to cucumber mosaic virus

Genetic Resources and Crop Evolution, 1996
A total of 384 Cucurbita pepo and Cucurbita maxima accessions were evaluated in growth chambers or glasshouse tests for resistance to cucumber mosaic virus (CMV). Seedlings were mechanically inoculated at the cotyledon stage, and scored for symptoms on cotyledons and true leaves 7 and 18 days after inoculation.

[Spectrophotometric analysis of phytochrome in the embryo of Cucurbita pepo and Cucurbita maxima].

Planta, 2014
Phytochrome detection and △ (△O.D.) measurements were made for the first time in a single embryo of pumpkin or gourd thanks to an apparatus adjusted to the differential spectrophotometer constructed by Dr. Spruit (Wageningen). Observed △ (△O.D.) values are comparable with usual values obtained by analysis of several seeds in a cuvette. The differential
