AbstractBlack seed of Scots pine are more resistant to damping‐off. The content of certain elements and chemical compounds in the seed coats differs widely depending on seed colour and physiological state (resting, germinating and infected seeds). The quantitative and qualitative differences in fatty acids content, total nitrogen, amino acids, some ...

Coherent photon seeding in a colour-centre laser
Optical and Quantum Electronics, 1993We report on a full-scale numerical simulation of the coherent photon seeding technique applied to colour-centre lasers with counterpropagating beams. The stabilization technique is proved to be simple and efficient independently of the interferometric precision of the coupled cavity.

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.

Rapeseed seeds colour recognition by machine vision
2008 27th Chinese Control Conference, 2008Rapeseed is one of the important oilseed crop species, and is worldwide the most important economically. The light seed colour in rapeseed is associated with improved oil, protein and fibre contents. But there are not reliable and efficient methods to measure seed colour, especially the single seed colour.

Inheritance of seed colour in alfalfa.
1934This paper presents the results of an investigation to determine the inheritance of black and white seed coat colors in alfalfa. The "black" character appeared to have arisen as a mutation in a third generation selfed line. Black x Yellow hybrid progenies in F2 exhibited a wide range of seed coat color extending from normal yellow to dark mulatto ...

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

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.

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.

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,
