It has been planting and appraising 115 varieties of barley which were introduced from foreign country and other province since 1983. The high-yield and high-Quality variety-Humai No. 4 was selected. Through four years experiments it is revealed that Humai No. 4 got 200--270kg per mu under different natural conditions in Guangxi. It is high resistant to lodging and stress tolerance. Grain quality satisfied the requirements of beer-brewage. The growing period of this variety became shorter with the latitute...

It has been planting and appraising 115 varieties of barley which were introduced from foreign country and other province since 1983. The high-yield and high-Quality variety-Humai No. 4 was selected. Through four years experiments it is revealed that Humai No. 4 got 200--270kg per mu under different natural conditions in Guangxi. It is high resistant to lodging and stress tolerance. Grain quality satisfied the requirements of beer-brewage. The growing period of this variety became shorter with the latitute reduced but the required summation of temperature is limited at a stable value, i. e. about 1760℃. There are a clear turning point between the seeding time and yield gained. The yield reduced obviously when it was sowed after November 25. The results also indicated that it was suitable when the basic number of seedling was in the tange of 100--150 thousands per mu, and the yield got highest when the effective panicles reached 333 thousands per mu.

自1983年以來,引進(jìn)區(qū)外和國外115個大麥品種進(jìn)行試種鑒定,篩選出高產(chǎn)優(yōu)質(zhì)的啤酒大麥品種——滬麥4號。四年的試種表明,該品種在我區(qū)不同自然生態(tài)條件下,畝產(chǎn)可達(dá)200～270公斤,同時具有較強的抗倒性和抗逆性,其品質(zhì)完全符合釀制啤酒的要求。滬麥4號的生育期隨緯度的降低而縮短,但所需的積溫則基本處于一個穩(wěn)定值,即1760℃左右。播種期和產(chǎn)量的關(guān)系有一個明顯的轉(zhuǎn)折點,11月25日以后播種,產(chǎn)量明顯下降。適宜的群體結(jié)構(gòu)基本苗為10—15萬/畝左右,有效穗在33萬/畝左右產(chǎn)量最高。

Higher yield: juvenile self-root clones Haiken 1 and Haiken 2 which gave a mean yield per tree over 2 years 131％ and 143％ of their respective donor buddings; 3. Developmental stage returned from...

Hevea anther somatic plants which combines both the advantages of seedlings and buddings, is a juvenile self—root clone that has showed a number of desirable characteristics:1. Faster growth, girth increment 9-20％ faster than its donor buddings, that being able to reach the standard of tapability one year earlier;2. Higher yield: juvenile self-root clones Haiken 1 and Haiken 2 which gave a mean yield per tree over 2 years 131％ and 143％ of their respective donor buddings; 3. Developmental stage returned from mature: type to juvenile type. This is characterized by, (1) like seedlings anther plants having a strong taproot and lateral roots; (2) larger trunk conisity resembled to seedlings; (3) smaller included angle of shoots to stocks when budding made with budpatches from 1.5—year—old plants, which is quite different from mature—type with larger included angle of shoots to stock; (4) good uniformity in growth and morphological characters and (5) like seedlings with better stress tolerance and longer economic life.Besides, anther somatic plant can evade the undesirable effects of stocks on scions. Therefore, it is a promising new planting material.

花藥體細(xì)胞植株,集芽接樹和實生樹的優(yōu)點于一體,是一種幼態(tài)自根無性系,表現(xiàn)出許多優(yōu)良性狀: 1.生長快。比母體芽接樹快9—20％,大致可提早一年開割投產(chǎn)。 2.產(chǎn)量高。海墾1和海墾2花藥體細(xì)胞植株頭兩割年平均單株產(chǎn)量分別為母體無性系的131％和143％。 3.發(fā)育階段從老態(tài)回復(fù)到幼態(tài)。表現(xiàn)在:和實生苗一樣有一條粗壯的主根及一輪側(cè)根;莖干圓錐度大,酷似實生樹;取1.5年生植株的芽片芽接,抽生的嫩枝與砧木夾角小。這和老態(tài)型(抽生嫩枝與砧木夾角大)有明顯差別,植株性狀整齊一致;抗逆性強,經(jīng)濟(jì)壽命長,可排除砧木對接穗的不良影響。因此花藥體細(xì)胞植株是一種很有發(fā)展前途的新一代種植材料。
