Effect of Pour Into Soil and Spray on Leaves of Plant Growth Substances on the Root Out of Mulberry
Journal of Sericultural and Entomological Science, volume 20, issue 1, 1978, Pages 1~4
The root-out of mulberry saplings has been studied by pour into soil and spray on leaves of the plant growth substances. In addition, the effect of "Rutin", a kind of plant growth hormones has been also studied on promoting the rootability of mulberry scions by dipping the scions at the various concentrations. The results are summarized as follows: (1) It is likely to be effective on acceleration of the rootability resulting in increase of rooting ratio by pour into soil at the concentration of 1 ppm and 10 ppm NAA, 10 ppm and 100 ppm Rutin, and 5000 fold solution of Atonic, respectively (2) Growth of branch is only promoted by leaf spray of 0.5% urea, 0.005% and 0.01% Rutin, and 5000 fold solution of Atonic without increasing the root weight. (3) It seems that 0.05% of Rutin is of practical use, and 0.05% to 0.4% of "Rutin" accelerates the root-out of mulberry scions as well as NAA does.
Effects of Foliar Spray of Kinetin (6-Furfurylaminopurine) on the Growth of Mulberry Tree and the Metabolic Activties in the Leaves (II)
Journal of Sericultural and Entomological Science, volume 20, issue 1, 1978, Pages 5~10
The effects of foliar spray of Kinetin (6-Furfurylaminopurine) on the growth of mulberry tree and the metabolic activities in the leaves were measured. The results of this experimented are summarized as follows: 1. Foliar application of Kinetin was effective in increasing of leaf area, the fresh and dry weight of the leaves, the length and diameter of shoots. 2. Chlorophyll content was generally increased in all treated leaves. 3. All the treated leaves were higher in GOT activity than the control leaves but were lower in GPT activities. 4. The activities of the carbohydrate metabolism in the mulberry leaves were higher than that of the control in all treated leaves.
Changes of Fluorescent Substances and Free Amino Acids in Formed Eggs of the Silkworm(Bombyx mori)
Journal of Sericultural and Entomological Science, volume 20, issue 1, 1978, Pages 11~14
This experiment was attempted to investigate the effect of removal of suboesophageal ganglion of Bombyx mori on the changes of free amino acids and fluorescent substances by means of paper chromatography. 1. There are no differences of quantity and component of free amino acids of formed eggs in moths between treatment and control. 2. Riboflavine content of formed eggs in treated moths is less than that of formed eggs in untreated moths. 3. Fluorescent substance which appeared on Rf value 0.06 was not detected in formed eggs of treated moths but found in those of control. 4. Fluorescent substance which appeared on Rf value 0 was noted in formed eggs of treated moths but not in those of control.
Urea Resin Treat Effects on Silk Textiles
Journal of Sericultural and Entomological Science, volume 20, issue 1, 1978, Pages 15~23
This studies have been carried out for several years to develop more better urea resin treating process on silk textiles which may be better crease resist without harming on the textile touch feeling. Specially, this paper payed attention to minimize the necessary formaldehyde content to be condensed with urea and created a new processing method which is named as Homo Metalic Urea Resin found to be better than urea resin process. The obtained results are as followings. 1. The prepared urea resin was found to be smell-less because of minimized formaldehyde content is the least than any other reports carried out before than this. 2. A new type of urea resin has been created by using uric 2incchloride and formaldehyde which is named as Homo Metalic Urea Resin. This processing method may carry both weighing process and urea resin process. 3. Crease resistance, stiffness and bulkiness were increased through such resin treats. Homo metalic urea resin process showed better results than the urea resin process. 4. Spun silk or low twisted silk have shown better crease resistance than raw silk or high twisted silk upon the both resin treats. 5. Both treat methods were found to be good economical feasibility upon the silk finishing process. 6. Tenacity and elongation of silk fibers were found to decrease some what because of grafting or weighing results. 7. Wooly silk has been also created with specific urea resin process. Such silk could be obtained by formaldehyde gas treat with urea soaken silk in a chamber, which induced to form scale on the surface of silk fibers.
