1. Firmiana simplex has been cultivated by our Chinese people in both ancient and modein times for medical use, and for the making of furnitures and musical instruments, as well as ornamental tree.2. The distribution of this plant is wide-spread almost through entire China. According to the writer's observation it grows vigorously and reaches its maximum height in the lower part of the Yangtze basin.3. In 1929 Yen states that sex differentiation of Firmiana simplex might be due to the fact of nutrition, the writer, after visiting various parts of China, discovered that everywhere this plant has the same phenomenon of sex differentiation. This fact leads to a new conclusion that sex differentiation in this plant is certainly not entirely influenced by nutrition; it may be due to the historical factor of the plant it-self.4. No phcllum is developed in the hypodermis except in the region of Icnticels. Epidermis, therefore, may grow permanently and never break off. These are very rare even among the perennial woody plants.5. Characteristics which are considered peculiar to Firmiana simplex are: (1) closely arranged epidermal cells may become loose during the increase of the diameter of the branches, (2) rupturing of the fissures on the bark while the branch grows, (3) development of secondary epidermis from the hypodermal cells within the fissures and the lenticels, and (4) continuous division of the epidermal cells. All these characteristics are facts which explain the permanence of epidermis.

1、梧桐具有观赏,药用,制造器物等价值,我国民众自古就加栽培利用。 2、梧桐上分布几遍及全国,据我所见到的是长江中、下游地区所生长的比较繁茂高大,北京的最为矮小,厦门比北京的高大些,昆明虽然不及长江流域的但比厦门的似乎又茂盛高大些。 3、关于梧桐花两性分异,以前以为是养料的关系,但是现在观察了各地的梧桐花,发现它们对于性的分异都是一样之后,我认为造成性的分异可能下仅是单纯养料的问题。也许和有机体自身的历史发展因素有关。 4、苹婆和大多数多年生木本植物相同,它们茎部表皮的寿命不过1年。新枝条的下皮层在当年夏秋之际分化木栓组织。以后,表皮细胞就会枯死脱落。 5、梧桐,除皮孔而外,枝干表皮层之下一概不发生木栓组织,表皮层与枝干同寿,这是多年生树木中少有的微状。 6、梧桐表皮细胞,随枝干之加粗而疏离,又可分裂增多,同时条状裂纹也可以随枝杆直经之增加而开裂加宽,这些都是表皮长生不老的因素。 7、梧桐树皮裂纹中的下皮细胞向外分裂成为次生表皮组织,这是很特别的。

野麻屬夾竹桃科,是一种野生的高級纖維植物。野麻在我国共有兩屬三种,即大花罗布麻,紫斑罗布麻和披針叶茶叶花。大花罗布麻是荒漠、半荒漠地帶的种,在我国广泛的分布于新疆,甘肃河西,青海柴达木盆地及都蘭和内蒙的西部,而以新疆分布的为最多,生長的也最茂盛,其它各地不見分布。紫斑罗布麻仅見于新疆,远不如大花罗布麻和茶叶花常見。披針叶茶叶花在我国崑崙山、巴顏喀喇山、秦嶺、淮河以北的西北及北方各省都有分布,而以新疆、甘肃河西、青海、山东沿海及河北省分布为最多。各种野麻都是多年生草本植物,具強大的多年生的根莖及根,用种子及繁殖根进行繁殖。野麻均生于低平的冲积土壤上,一般均依強大根系吸收地下潛水,故能杭大气干旱,能抗酷热,酷寒,也能抗风。此外,茶叶花的抗淤抗涝性相当強,罗布麻适应流沙的力量也相当強,野麻的抗鹽性也相当強,一般多分布于輕鹽化的土壤上,而且生長很好。野麻是我国西北及沿海鹽碱荒地上的主要植物。收割与管理野麻田是利用这些荒地的重要途徑。野麻是一个有希望引种的植物。野麻的利用与引种苏联有丰富的經驗,应尽速加以吸取,以便能迅速地更好地利用与栽培这种資源植物。

The severity of red-leaf disease of millet, as measured by the height as well as the yielding capacity, is directly correlated to the stage of development of the plants at which infestation takes place. As a rule, plants infested at seedling stage are much more damaged than those infested at the later stages of development. Date of sowing effects the percentages of diseased plants. In general, earlier sowing produces more diseased plants than later sowings. Nevertheless, it is largely determined by the prevalence...

The severity of red-leaf disease of millet, as measured by the height as well as the yielding capacity, is directly correlated to the stage of development of the plants at which infestation takes place. As a rule, plants infested at seedling stage are much more damaged than those infested at the later stages of development. Date of sowing effects the percentages of diseased plants. In general, earlier sowing produces more diseased plants than later sowings. Nevertheless, it is largely determined by the prevalence of the migrating aphids. Introducing corn aphids, in the previous autumn, on host plants of red-leaf virus, including 11 species of perannual gramineous weeds, under screen cages in open field, did not reveal the presence of either survival insects or egg mass during the next spring. It indicates that the corn aphids don't overwinter on these weeds under the present experimental conditions. Two species of perannual weeds, viz. (Panicum virgatum L. & Boutelona curitipendula (Michx.) Torr.),are found to carry the virus over the winter under natural conditions. Attempts for controlling the disease with organic phosphorus insectides have been so far? unsuccessful. Among 200 or more varieties and strains of millets, 4 of them have been proved to be highly tolerant to the disease and possessing desirable agronomic characters.

在田間隔离昆虫传染的条件,于小米不同生长期所进行的人工分期接种試驗,証明接种期愈早对植株的生长和产量的影响愈大,并发現根系受紅叶病毒的影响最为显著。在田间条件下不同播种期对小米感染红叶病的百分率的影响不大一致,但根据两年的結果,早播一般均较正常播种期的发病率为高。人工飼育蚜虫的試驗,未发現玉米蚜能在鵝冠草等11种多年生禾本科杂草上越冬。在所測定的11种植物中,小米紅叶病病毒能在黍草(Panicum virgatum L.)和垂穗草(Bouteloua curitipendula(Michx.)Torr.)上越冬。三年的試驗証明,田间不同时期噴射內吸杀虫药剂虽可減少蚜虫数量,但对小米产量和紅叶病发病率均无显著影响。对二百多个小米品系連續四年进行紅叶病抗病性的鑑定,发現大多数品种都是高度感病的,沒有抗病和免疫的品种,但有許多高度耐病的品系。选出耐病而且农艺性状良好的P14A、NP—157、P354和摩里等四个品系。
