The utilization of fire occupies an important place in the development of mankind and in the history of the development of human society. It is a great progress made by humanity from its acquisition of the ability of using fire to its acquisition of the ability of making fire.

An investigation,on the bud and the root with regard to the stubble cane and its pro-duction,had been carried out,during the years 1961 and 1962 in Fukien province,and thepreliminary results were summarized briefly as follows:1.By employing the radio-active element p32 as a tracer,it was shown that the old rootsystem of the stubble was capable of absorption early in the growing season.In so doing,the stubble cane was able to make an earlier start in growth than that of the newly plantedcane.(See tables 1 to...

An investigation,on the bud and the root with regard to the stubble cane and its pro-duction,had been carried out,during the years 1961 and 1962 in Fukien province,and thepreliminary results were summarized briefly as follows:1.By employing the radio-active element p32 as a tracer,it was shown that the old rootsystem of the stubble was capable of absorption early in the growing season.In so doing,the stubble cane was able to make an earlier start in growth than that of the newly plantedcane.(See tables 1 to 3).2.We found that permanent roots appeared on the ratoon,soon after its emergence fromthe stubble cane,while,in contrast,the newly planted cane produced only permanent rootsafter it possessed two true leaves.The ability of the ratoon to produce permanent roots de-pended on the number of bud scales.Usually,the more the number of scales,the earlier andbetter production of permanent roots.(See tables 4 to 5).3.The number of bud scales on buds appearing at different nodes on the same cane wasfound to be different,being more at the basal portion,and decreasing in number toward thedistal end.Likewise,the number of scales on an opened bud was found to be higher thanthose of the unopened ones on the same node in different cane.(See tables 9 to 12).4.New canes arising from buds occurring on the basal portion up to a height fivecentimeters of the residual stock were larger,more vigorous and constituted the effectivecanes in crop production.It was further shown,that the crowded nodes,often enveloped inthe scales of the residual stock,were able to differentiate normal and healthy buds.Themanner and time of the formation of these buds remained as problems to be studied later.(See taables 6 to 8).5.We would like to stress the fact that the performance of the buds and the roots forthe stubble canes referred to above as important factors in sugar cane production,wasintimately linked up with the external factors including cultural operations.The productionof earlier,more and stouter canes was often influenced by a number of cultural treatmentsthey received during the previous season.Among these cultural treatments,we listed thefollowings:(1) harvesting of canes properly conducted;(2) good care and protection ofstubbles through the winter;(3) proper cultivation and preparation of cane beds during earlyspring;(4) adequate fertilization,cultivation and irrigation of the preceding crops;and (5)chemical and biological control measures of pests and diseases well executed.(See tables 13to 28).

Bromoacetate and iodoacetate have been found to be strongly inhibitory to the activity of papain at pH 5 even in the presence of excess cysteine; the activity of the enzyme for the hydrolysis of benzoyl arginine amide, leucinamide or haemoglobin was completely suppressed when the molar ratio of inhibitor/enzyme reached 0.5. The content of sulphydryl groups of the enzyme was not changed after the inhibition by bromoacetate have reached completion under these conditions. Papain thus carboxymethylated can still...

Bromoacetate and iodoacetate have been found to be strongly inhibitory to the activity of papain at pH 5 even in the presence of excess cysteine; the activity of the enzyme for the hydrolysis of benzoyl arginine amide, leucinamide or haemoglobin was completely suppressed when the molar ratio of inhibitor/enzyme reached 0.5. The content of sulphydryl groups of the enzyme was not changed after the inhibition by bromoacetate have reached completion under these conditions. Papain thus carboxymethylated can still be crystallized like the unmodified enzyme.The rate of reaction between bromoacetate and papain was greatly lowered in 6 M urea; both the substrate, leucinamide, and the inhibitor p-chloromercuri-benzoate, were effective in the protection of the enzyme against the action of bromoacetate. It appears therefore, that the ability of papain to react with bromoacetate is closely related to the catalytic activity of the enzyme, and bromoacetate acts, most probably, at the active site of the enzyme.The amino acid compositions of papain, carboxymethyl papain, ribonuclease, carboxymethylribonuclease prepared according to Gundlach et al., have been analyzed by two-dimensional paper electrophoresis-paper chromatography and compared with S-carboxymethyl cysteine and Im-carboxymethyl histidine. The results showed that histidine but not cysteine was the point of attack by bromoacetate at the active site of papain under the above conditions.

(1)在过量半胱氨酸存在下微量溴代乙酸或碘代乙酸在pH5对木瓜蛋白酶有強烈的抑制作用,当抑制剂与酶的克分子比为0.5时,抑制即达完全。抑制前后木瓜蛋白酶巯基含量不变。溴代乙酸作用后所得到的羧甲基木瓜蛋白酶汞盐結晶,与木瓜蛋白酶汞盐結晶相同。(2)在6M尿素溶液中溴代乙酸与木瓜蛋白酶的作用速度显著降低,底物L-白氨酰胺及抑制剂对氯汞苯甲酸都具有保护作用。这些事实表明溴代乙酸的抑制与木瓜蛋白酶的催化活性有密切关系,其作用点很可能是活性中心所在。(3)以双相电泳层析进行氨基酸組成分析結果指出,溴代乙酸作用点很可能是組氨酸殘基。
