Infection of Plasmodiophora brassicae in Chinese cabbage.
Brassica crops infected by Plasmodiophora brassicae can produce root galls (clubroots) and be prevented from growing normally. To understand the series of changes that occur in the host root during root gall production, the resistance character of 21 Chinese cabbage lines were identified and then resistant and susceptible lines were used for infection observation. Hydroponic technology system w...
متن کاملKinetin and carbohydrate metabolism in chinese cabbage.
The effects of kinetin on starch and sugar levels and on (14)CO(2) and (32)P-orthophosphate labeling patterns of floated Chinese cabbage (Brassica pekinensis) leaf discs were investigated. Kinetin caused gross starch degradation. Neutral sugars were depressed by 30 to 40% in leaf tissue treated with kinetin for 24 hours. (14)CO(2) labeling of leaf discs pretreated with kinetin for 24 hours show...
متن کاملMale Sterility of Chinese Cabbage, Wheat and Rice: Cell Biological Research on the Process of Anther Abortion
Male sterility of higher plants is a valuable trait used to improve agricultural crops through hybridization. Pollen abortion is a complex and complicated process and the mechanisms involved are actively being studied. Recently, new data on the structure and function of the tapetal cell, changes in Ca distribution, ATPase activity distribution and programmed cell death in anther cells were obta...
متن کاملFrom Chinese Cabbage and Photosynthetic Microorganisms
Ribulose-1,5-diphosphate carboxylase (carboxydismutase) was prepared from Chinese Cabbage [Brassica petsai (Parl)] and the Km values and molecular weight were determined. These parameters were found to be in good agreement with values reported for this enzyme from other higher plants. Investigation of carboxydismutase activity from the photosynthetic micro-organisms Chlamydomonas reinhardi (IU ...
متن کاملThe Physiology of Self-sterility in Plants
Hermaphroditic animals and plants are known where fertilization of the eggs by the sperm or by the pollen produced by the same individual is very unusual. The extent of the phenomenon in the animal kingdom is unknown, Ciona intestinalis, an ascidian, having been the only species used in experimental work. In the angiosperms, the characteristic is widespread, and must be supposed to have origina...
