Contribution to the study of the effect of a low dose of gamma irradiation on seeds and tubers before planting; Contribution a l'etude de l'effet d'une irradiation gamma a faible dose sur les graines et tubercules avant plantation

Abstract

From 1962 to 1965, 25 tests have been made with carrots (1 variety), radish (3 varieties), spinach (2 var.), tomatoes (2 var.), potatoes (2 var.), barley (2 var.), rice (3 var.) and corn (1 var.), with the object of studying the interest for agriculture of seed and tuber gamma irradiation at low dose before planting. These tests were made in the laboratory, in greenhouses and in the open field, all necessary care being taken for a valuable statistical analysis of- the results. Special attention was paid to the homogeneity of plant material by controlling more particularly moisture content of seeds and the storage conditions of tubers. The observations concerned germination, growth at early stages, development phases and yield of leaves, roots and fruit. Some stimulation cases are observed. For tomatoes, it is found that stimulation cases occur at extreme moisture content and not in the range of mean moisture content which corresponds to maximum radioresistance. The demonstration of these effects is related to varieties, complementary treatments, conditions of cultivation and observation criteria. In most cases, they are short-lived and suitable modifications of seed conditioning produce, upon controls, an effect equivalent to that of irradiation. In conclusion, it seems very unlikely  More>>

(authors) [French] Dans le but d'etudier l'interet agricole d'une irradiation gamma a faible dose des graines et tubercules avant plantation, 25 essais ont ete mis en place de 1962 a 1965 sur carotte (1 var.), radis (3 var.), epinard (2 var.), tomate (2 var.), pomme de terse (2 var.), orge (2 var.), riz (3 var.) et mais (1 var. ). Les essais ont ete faits au laboratoire, dans les serres et en plein champ avec toutes les precautions requises pour une analyse statistique valable des resultats. On a prete une attention particuliere a l'homogeneite du materiel vegetal en controlant notamment la teneur en eau des graines et les conditions de stockage des tubercules. Les observations ont porte sur la germination, la croissance dans les jeunes stades, les phases de developpement et le rendement en feuilles, racines et fruits. Un certain nombre de cas de stimulation sont observes. On constate, sur tomate, qu'ils se produisent pour des teneurs en eau extremes et non dans la zone des teneurs en eau moyenne qui correspond au maximum de radioresistance. La manifestation de ces effets depend des varietes, des traitements complementaires, des conditions de culture et des criteres d'observation. Dans la plupart des cas, ils sont de courte duree et des modifications convenables du conditionnement des semences produisent sur les temoins des effets equivalents a ceux de l'irradiation. La conclusion du present travail est que dans nos conditions de culture il parait tres peu probable que l'irradiation des graines et tubercules avant plantation puisse avoir un interet agricole.
