Journal Article 1999

Autor: Barker, D.J. Keatinge, J.D.H. Asiedu, Robert

A range of physical means of manipulating yam tuber dormancy was tested, including the use of temperature, water, electric shock, microwave, heat and storage treatments. Most treatments had very little practical effect on tuber dormancy though differences in dormancy length between clones were de...

To analyze the mechanism of dormancy in tubers of water yam (Dioscorea alata L.), we studied the relationship between external factors and dormancy and its release in tubers. Several strains of water yam that have been introduced into Japan from Southeast Asia and Oceania were grown in Kagoshima,...

Yam cultivation in dry season was tested in the farmer’s field at inland valley in Niger state, Nigeria. Water yam (Dioscorea alata) variety TDa 95/00328 had the greater response to the gibberellin inhibitor prohexadione-calcium (PC). The sprouting period of PC treated tuber was 21 – 27 days at D...

Tuber dormancy is of major importance in yam production, but the lack of a method to consistently break dormancy restricts the rate at which new clones can be multiplied to release to farmers. Much of the work on yam tuber dormancy was small scale, using only one or two clones and a few tubers. O...

Dormancy in seeds of Sesbania sesban is caused by a water-impermeable seed coat (hard seeds or hardseededness). A two-phase pretreatment technique was developed for breaking seed dormancy and was validated using different accessions and seed lots. Seeds were first soaked in water at 80 °C for 8 m...

En cinco muestras de semillas de B. dictyoneura cosechadas en la misma época en Colombia, Panamá y Costa Rica, se evaluó el efecto de tres niveles de calor seco (ambiente, 40 y 60°C) y tres tiempos de exposición (0, 72 y 240 h) aplicados a uno y tres meses poscosecha en espiguillas completas o es...

Inadequate yield potential of available varieties and their long growth periods are two of the factors limiting yam (Dioscorea spp.) production. Identifying yield- and maturity-related traits and breeding for them will enhance production. Ten morphological/physiological traits: time of shoot emer...

The tubers of yam, principally those of Dioscorea rotundata (white Guinea yam) and D. alata (water or greater yam), are important staple foods and sources of carbohydrate in West Africa. Yams are grown in diverse environments – from the high-rainfall forest zone on the coast to the seasonally ari...

Germination studies with 11 rice varieties (Oryza sativa L.) indicate that there are significant differences in the duration and intensity of dormancy of this varieties. Removal of the hull increases germination of seed with long and medium dormancies. The treatment with heat (4 days 50C) is a go...
