Abstract
In the previous paper, it was shown that the growth of flowers of tomato plants exposed to lower temperatures were prominently invigorated and much more locules were formed, and such responses in tomato flowers may be attributed to surplus nutrient supply to young flower buds.This paper reports the results of the study on the effects of light intensities and soil fertilities on the development of tomato flowers, especially that of the ovaries and their locules.Tomato seedlings were grown at four different light intensities (100, 75, 50 and 25 per cent of natural day light) and at three different levels of soil fertilities.The lower light intensities and or the poorer soil fertilities retarded the morphological development of flowers and hence resulted in forming smaller flowers with smaller sepals, petals, anthers, and ovaries.The flowers of the plants grown under natural day light condition and/or fertile soil condition developed most remarkably, and their ovaries attained the highest size, and their sepal and locule numbers highly increased. The flowers of plants grown at lower light intensities and/or in poorer soil fertilities less developed and their sepal and locule numbers were fewer.These results suggest that the seedlings grown at lower light intensities were at lower levels of carbohydrates, and the ones grown in the soil of lower fertilities were at lower levels of nitrogenous and phosphorous constituents in the whole tomato plant, and poorer flower development in such cases may be attributed to restricted nutrient supply to young flower buds.
