Citrus in South China is affected with a highly destructive disease known as"Yellow shoot".The disease is most serious in the Chaoshan and the Yuehchungdistricts of Kwangtung Province and in the Changchow district of Fukien Province.It has been known in the Chaoshan district for over 70 years but has becomeepiphytotic only since about 30 years ago.During this period,millions of Citrustrees have been killed. Citrus trees may be affected in any age.The characteristic symptoms of thedisease are general yellowing of some of the nearly mature new shoots put out insummer,autumn,or early winter,dropping of the yellow leaves,and rotting ofrootlets.In addition to these general symptoms in the early stage,fasciculationof branches and malformation of leaves (abnormally large or deformed in variousways) often occur on Ponkan and Chiaokan (C.reticulata) and are particularlycommon on sweet orange.On affected sweet orange trees may also be seenshortening of internodes,resulting in bunchy growth of branches,and downwardas well as upright growth of shoots.In a later stage,the affected tree puts outnew shoots as usual but such shoots generally become chlorotic showing zinc ormanganese deficiency symptoms.The midrib and lateral veins as well as theadjoining tissues of part of the older leaves turn yellow.The midrib and largerveins may also become enlarged and corky and often split on dorsal side,showingnitrogen and boron deficiency symptoms.Affected trees blossom earlier and moreheavily than usual but bear few fruits.On badly affected trees fruits matureearlier but do not color well and are often deformed.Defoliation and root rottingbecome progressively serious as the disease advances.Young trees below 7 yearsof age generally are killed in 1 to 2 years or sooner.Nursery trees are killedeven more quickly.Older trees decline less rapidly but generally become unpro-ductive in about 2 years after the first symptoms appear. Nearly all the species and varieties of Citrus grown in the affected area aresusceptible.The order of degree of susceptibility is as follows: Ponkan,Chiaokan,Chachihkan,Lukan,Tungkan (all (C.reticulata),various varieties of sweet orange(C.sinensis),Hungninmeng (hybrid of C.lemon and C.rcticulata) Nienchu (C.rcticulata),Shangmayu (C.graudis) and Shihchichu (C.mitis). Studies of the cause of the disease will be reported in a later paper.

广东的潮汕区、新会县、番禺縣、广州市郊,福建的龍溪縣、福州市郊,和广西的柳城、融縣、兴業縣、郁林縣的柑桔类,都發生一种毁滅性的病害称为黄梢,或黄龍病。病区各种柑桔类的各品种一般都很易感染。其感病程度的次序大約如下:栟柑、蕉柑、茶枝柑、蘆柑、桶柑、各种甜橙、紅檸檬、年桔、桑麻柚及四季桔。用实生苗繁殖的福州紅桔及廣柑(橙),和福建龍溪的坪山柚及文旦柚,則未見發病。各齡的柑桔樹——自苗木至20齡以上的老樹——都能感染,一般以3—8齡的幼樹受害最烈?静〉闹饕钗跗诓糠中律业囊度烤然苹T谔鸪取薷毯徒陡躺嫌幸徊糠只苹蛘>G色的叶特别肥大或呈各种畸形狀态,有許多新梢簇生或束化。發病的枝条很快落叶。老枝上的叶有一部分亦黄化脫落。根系腐烂。至發病中期,新梢的叶多呈缺鋅或缺锰病狀,老叶呈缺氮及缺硼病狀,落叶及根腐更嚴重,开花早而多,結果少,部分枝条枯死。到后期,全株嚴重雕殘,終而枯死。本病在70—80年前在廣东潮汕区已有發现,但在近30年來始在各地蔓延成灾壳氨静≡诠愣鄙乔V州市郊及新会縣和福建龍溪縣已成为柑枯業發展的限制因素。

In the experiment sweet orange trees of 30-40 years age were chosen as experimental materials in which moisture metabolism and nutrient metabolism were studied and compared between the off-year preparing branches of being able to have flower bud differentiation (non-bearing spring flush and autumn cycle shoots) and the on-year preparing branches of not being able to have such differentiation.

作者选用已成隔年结果的甜橙作试材,对比了能够进行花芽分化的小年预备枝(春梢营养枝和秋梢)和不能分化花芽的大年预备枝的水分代谢和养分代谢的差异,并且分析了稳产类型的生理生化特性。结果表明,小年预备枝干物质累积较高,在花芽生理分化期含有较低的水分,较高的水溶性糖,较低的全氮量,较高的磷、钾和较低的钙、镁含量。而且,在年周期中水分恒低,磷、钾恒高,钙元素恒抵。在生理分化期水分降低,水溶性糖含量升高,细胞液浓度升高,全氮含量降低,即C/N值升高。花芽分化开始后,细胞液浓度和C/N值旋即降低。但是大年预备枝也有类似的变化,只是变幅较小而已。从大年含水恒高于小年,水分含量与载果量成正比来看,极可能大年时果实发育合成了过多的赤霉素,从而引起上述一系列的生理变化,并强烈地抑制了预备枝的花芽分化。

The trees of sweet orange on sunki stock infected by yellow shoot disease were injected with achromycin, terramycin, aureomycin, penicillin, chloromycetin, streptomycin, sulfadiazine or p-aminobenzoic acid in various concentrations.Achromycin is most effective to suppress the symptoms of this disease. A dosage of 5000-8500 ml in 1000 ppm of achromycin was used for the 11 years old orange trees with trunk diameter between 11.5~15cm.

The trees of sweet orange on sunki stock infected by yellow shoot disease were injected with achromycin, terramycin, aureomycin, penicillin, chloromycetin, streptomycin, sulfadiazine or p-aminobenzoic acid in various concentrations.Achromycin is most effective to suppress the symptoms of this disease. A dosage of 5000-8500 ml in 1000 ppm of achromycin was used for the 11 years old orange trees with trunk diameter between 11.5~15cm. Trees which have been injected bear normal fruits and produce healthy shoots for three years. The accumulation of starch in the infected leaves disappeared within eight days after injection.The symptoms could also be suppressed by terramycin, aureomycin, penicillin and most of the shoots could grow normally by the application of sulfadiazine. No remarkable response to streptomycin, chloromycin and p-aminobenzoic acid has been observed.

试验用六种抗菌素及二种化学药物加压灌注黄龙病树,结果表明:四环素、土霉素效果较好,金霉素、青霉素及磺胺嘧啶亦有一定抑制病情的作用,链霉素、氯霉素、对氨基苯甲酸效果不明显。对柑桔黄龙病病株灌注盐酸四环素八天后,斑驳病叶中的淀粉积累现象逐步消失。新梢生长、花芽发育均正常,落果现象明显减少。果实大小、品质均与健树无明显差异。对主干中段的直径为11.5~15厘米的刚发病11龄甜橙树,注入每毫升合1000单位的盐酸四环素溶液5000~8500毫升。注药后彻底剪除病枝。杩势恢复后三年不出现症状。使用量偏低的病株、症状短期内受到抑制,但以后会再度出现。
