Previous and his coworkers(1944)have reported the preparation of5-deoxy-L-lyxosc.benzylphenylhydrazone from L-faconic amide by means ofWheerman reaction.Now,5-deoxy-L-lyxose itself has been synthesized by twodifferent methods.The first method is based upon Ruff degradation of calciumL-fuconate,which is prepared from D-galactose through conversion into diethylmercaptal of sodium galactttronato followed by demercaptalization.The secondmethod consists of alkaline degradation of L-fucose-l,l-diethylsulfones accordingto H.O.L.Fischer.The crude 5-dooxy-L-lyxoso obtained has been purifiedthrough the preparation of its crystalline ethylenemercaptal(m.p.108—109℃,[α]_D~(20)-26.3°(c,1.94,methanol.)).The analytically pure dooxy-sugar is a sirup of[α]_D~(62)=-21.6°(c,3.33,water).It can be characterized by its crystalline derivativeslike benzylphenylhydrazone,ethylene mercaptal and dibenzyl mercaptal triace-tate(m.p.77—78℃,[α]_D~(18)-205.4°(c,2.03,methanol)).On oxidation of L-fucose-diethylmercaptal with hydrogen peroxide in presenceof trace of ammonium molybdate,two isomeric L-fucose-1,1-dicthylsulfones ofthe same empirical formula C_(10)H_(20)O_7S_2 are formed,one of which is an unsatu-rated sulfone(sulfone A)and the other,a saturated isomer(sulfone B).Sulfone A(m.p.137°)decolorizes permanganate solution,gives red color with pyridine,andshows an absorption maximum of λ_(max) 261.5 mμ(methanol),while sulfone B islacking of these properties and forms a diacetate C_(10)H_(18)O_7S_2(COCH_3)2.From thephysical and chemical-properties of these sulfones it seems that sulfone A is mostpr6bably 1,1-diethylsulfonyl-L-lyxo -3,4,5-trihydroxyhex-1-ene(X),and sulfone B,1,1-diethylsulfonyl-L-talo-2,5-epoxy-3,4-dihydroxyhexane(Ⅺ).Paper chromatography shows preliminarily that the pentamethylose and thehexamethylose have grater R_f values than their corresponding pentose and hexose.

由二种方法合成了5-脱羟-L-来苏糖。第一法自 D-半乳糖醛酸制成其二缩乙硫醇钠盐,经脱硫成为 L-岩藻糖酸钙,再行 Ruff 降解而得5-脱羟-L-来苏糖;第二法自 L-岩藻糖合成其二缩乙硫醇,经氧化得二种二乙砜异构体(砜甲和砜乙),二者经 Fischer(H.O.L.)法降解得同一脱羟糖。由第一法所得粗糖浆借其缩乙二硫醇衍生物的制备而纯化。5-脱羟-L-来苏糖是一种粘稠的糖浆[α]_D~((?)2)=-21.6°。其苄基苯腙、缩乙二硫醇和二缩苄硫醇三乙酸酯都是很好的晶体,能用以鉴定该糖。根据紫外吸收光谱,高碘酸的消耗,以及对高锰酸钾和吡啶的反应,砜甲似为开链式不饱和的二乙砜,砜乙似属饱和的呋喃型二乙砜。从纸层析的初步结果指出末端脱羟的戊糖或己糖的比移大于相应的母糖。

With the expansion of soybean leaves, their orthophosphate content decreasedand starch content increased markedly. There was less accumulation of sucrose,which increased only sightly with a decrease in Pi (Fig. 1).When the soybean plant was treated with Pi at different concentrations, theincrease of Pi content in leaves was accompanied by a rapid decrease in the ac-cumulation of starch and a rapid increase in the accumulation of sucrose (Fig. 3).Obviously, the less the Pi in the leaves, the more the starch accumulated,...

With the expansion of soybean leaves, their orthophosphate content decreasedand starch content increased markedly. There was less accumulation of sucrose,which increased only sightly with a decrease in Pi (Fig. 1).When the soybean plant was treated with Pi at different concentrations, theincrease of Pi content in leaves was accompanied by a rapid decrease in the ac-cumulation of starch and a rapid increase in the accumulation of sucrose (Fig. 3).Obviously, the less the Pi in the leaves, the more the starch accumulated, and, onthe other hand, the more the Pi in the leaves, the more the sucrose accumulated.That was the case with all soybean leaves irrespective of the age of the leaf (Fig. 2).These observations suggested that Pi played the role of regulating partition ofphotosythetes between starch and sucrose in the soybean leaves.In maize plant or its leaf discs treated with various concentration of Pi, thecontent of starch and sucrose increased with the increase of Pi content in leaveshaving originally low Pi level (Fig. 5A); when the content of Pi vareied in the range1.8~5.5‰ in the leaves (Fig. 5A) and in the range 2.5~6‰ in the leaf discs (Fig.5 B) respectively, the content of starch, sucrose and dry matter varied little (Fig.5A and 5B). When the leaves and discs contained Pi more than above rangescontents of dry matter, starch and sucrose decreased gradually. There was nodefinite relation between the quantity of starch and sucrose present with the changeof Pi content. These results show that the effect of Pi on the accumulation of starchand sucrose in leaves is different in different plants.When Pi was highly concentrated in the soybean leaves, the accumulation ofthe starch in them was reduced. That was due to the lengthening of a lag-phaseof the starch formation and the lowering of the speed of strach accumulation (Fig.4).

C_3植物大豆的叶片无机磷含量随年龄增长而降低,淀粉则显著增加。蔗糖积累数量较少,随叶龄增长略有增加。 不同浓度P_i处理的大豆植株,在光合不变的情况下,随着叶片中P_i含量的增加,淀粉积累不断减少,蔗糖不断增多。各种年龄的大豆叶片都在含较多P_i时有利于蔗糖合成,不利于淀粉合成。 C_4植物玉米经不同浓度P_i处理,叶淀粉与蔗糖的积累都稳定在一定水平上。P_i浓度过高时,积累数量都下降。在C_4植物玉米叶组织中,P_i含量的变化不是调节淀粉与庶糖合成的重要因素。在C_3植物大豆和C_4植物玉米的叶组织中,P_i对淀粉和蔗糖合成的影响是不同的。

The Short-Season cotton (Gossypium hirsutum) has a relative short developing period and a late planting date, but it matures and harwests early. It is characterised by fast development in the early season and a concentrated flowering and boll-setting period. However, the development of its main stem is also arrested early with a lower productivity potential and, thus, it'can not make full use of the effective flowering and booll-setting period. Therefore, early planting would cause an unavoidableyielddecrease....

The Short-Season cotton (Gossypium hirsutum) has a relative short developing period and a late planting date, but it matures and harwests early. It is characterised by fast development in the early season and a concentrated flowering and boll-setting period. However, the development of its main stem is also arrested early with a lower productivity potential and, thus, it'can not make full use of the effective flowering and booll-setting period. Therefore, early planting would cause an unavoidableyielddecrease. A suitable planting date on May 25 or thereafter can provide an optimum developing period for yield formation coinciding with the most effective sunlight-heat in space and time, to obtain high yield and good fibre quality. Physiological determination showed that the chlorophyll content in the main stem leaves of short-season cottons was always to certain extent higher than that of the mid-mature cottons no matter whether they were planted in spring or summer. The photosynthetic intencity of the short-season cottons was higher in the early and middle seasons and lower in late season, and reached the highest until the flowering and boll-setting period, but decreased gradually after the peak boll setting period. Under the summer sowing conditions, among the N contents, its protein nitrogen content was higher than that of the mid-mature cottons Within the whole growing season, the contents of 17 kinds of amino acid within the leaves of the short-season cottons were also higher to some extent than that of the mid-mature cottons. The contents of arginine, aminoglutaric acid and asparagine were much higher. The sugar synthesis and accumulation in the short-season cottons was a little lower, but it is 1 time higher than that of the mid-mature cottons, in the peak flowering and boll-setting period, which was very favourable for the boll and fibre development of the short-Season cottons.

短季棉品种(G.hirsutum)生长发育期短,晚播早熟。前期发育快,开花结铃集中,主茎停止生长早,生长潜力个。适宜播期应在5月25日以后,才能获得最佳产量和优质纤维。 生理测定结果表明,短季棉品种主茎叶中的叶绿素含量,无论在春播或夏播条件下,都不同程度地比中熟棉品种高。光合作用强度前中期高,后期低,花期达到最高峰。结铃盛期以后逐渐下降。在夏播条件下,短季棉品种的氮化合物中,蛋白质氮的含量高于中熟棉品种。在整个生长期中,短季棉品种叶片中的17种氨基酸含量也不同程度地高于中熟棉品种。 短季棉品种糖的合成和积累在初花期略低于中熟棉品种,盛花期和结铃期比中熟棉品种高一倍左右,这对短季棉品种的棉铃生长和纤维发育非常有利。
