Seed morphology and colour variation in derotinous Cape Proteaceae
, 2017 I investigated seed colour polymorphism in Leucadendron is investigated for the possibility of crypsis in a post fire environment. Results were inconclusive, possibly due to a missed opportunity, but do not exclude the possibility of crypsis. Seed predation by birds may be an as yet undescribed and significant phenomenon. Seed morphology and its impact

The colouring matter of the tamarind seed testa
Proceedings of the Indian Academy of Sciences - Section A, 1948The tamarind seed testa contains about 32 per cent. of tannins of which 35 per cent. is phlobatannin, the rest being mostly catechol tannin. The phlobatannin yields almost colourless methyl and acetyl derivatives which exhibit marked optical activity, supporting the idea that phlobatannins are probably hydroxy flavan derivatives.

Effect of seed size and testa colour on saponin content of Spanish lentil seed
Food Chemistry, 1997Twenty cultivars of Lens culinaris Medik. were grown over 5 years in 18 provinces of Spain. Saponin content in the harvested seed ranged from 654 to 1269 mg kg−1. Two saponins were detected and identified as soyasaponins I and VI. Changes observed in the saponin content were found to be dependent on both seed size and testa colour.

A study of the colour and other characters of the seed of some varieties of oil seed poppy
Euphytica, 1960Among oil seed poppy varieties differences exist in colour and shade of the seed. The best insight into the nature of a variety with respect to the colour and shade of the seed is obtained by examining seed of individual plants. Some varieties (Emmabloem, Nobel) produce seed of one colour; others (Noordster, Eckendorf selections) are composed of plants

Recovery and characterisation of coloured phenolic preparations from apple seeds
Food Chemistry, 2013The aim of this study was to investigate whether complexly constituted phenolic extracts from apple seeds may be utilised for the recovery of natural coloured antioxidant preparations, which might serve as potential food or cosmetic ingredients. In a first step, the recovery of phenolic compounds was optimised by varying crucial extraction parameters ...

The genetics of the presence of coloured stripes on the flower standard in common bean (Phaseolus vulgaris L.) was studied. One dominant gene was involved in the presence of purple stripes in PR1144-5/‘Badillo’ and 92BG-7/‘Verano’ populations. Furthermore, flowers without purple stripes co-segregated with light red and white seeds in both populations,

Effect of Seed Coat Colour on the Seed Quality of Water Melon (Citrullus Lanatus)
Africa Journal of Technical and Vocational Education and Training, 2018Water melon is one of most cultivated vegetable fruit crop in the world. In Kenya the demand for this fruit for both local and export markets outstrips the supply. For Kenya to meet the high demand for water melon, quality seed is paramount since it guarantees high germination rate and vigor and on sequential high crop yields.

Inheritance of seed colour in turnip rape (Brassica campestris L.)
Theoretical and Applied Genetics, 1982The inheritance of seed colour was investigated in the progenies of crosses between seven yellow seeded forms and a brown seeded one of turnip rape (Brassica campestris L.). Seed colour differences were found to be determined in each case by one or two genes with epistatic effect. Moreover, independent inheritance of hilum colour was observed.

Effects of seed coat colour on seed characteristics of honeylocust (Gleditsia triacanthos)
Honeylocust (Gleditsia triacanthos) seeds have hard seed coats of different colours that affect duration of dormancy. This study investigated the effects of seed coat colour on water uptake, germination, and quantity of seed parts. The results show that seed coat colour had a significant effect on seed moisture content, seed coat weight, endosperm ...Ertekin, Murat +2 more

Inheritance of Seed-coat colour in Gram (Cicer arietinum)
Madras Agricultural Journal, 1950It was stated in a previous paper by Ramanatha Ayyar and Balasubrahmanyan (1936) that the seed-coat colour Rood's brown corresponding to the seed grade CS 12 was formed by the addition of factor T to CS 10 and that T had no effect when P was absent.
