2。1。 Seed quality evaluation

2。1。1。 Mechanical damage

Three replications of 100 seeds were soaked in 1% sodium hypochlorite solution for 10 min。

The seeds with seed coat damage swelled visibly and were counted using a hand lens。 The split (%)

was obtained by passing 200 g of seed through a 4。00mm round hole sieve。 The material that

passed through the sieve was termed as ‘‘splits’’ and then weighed (Anonymous, 1985)。

2。1 豆種質量評估

2。1。1機械損傷

經過3遍流程的100顆豆種在1%的漂白液中浸泡10分鐘。種子以及種皮的很明顯地膨脹損壞可以透過手持透鏡觀測到。 破裂指數透過200g的種子經4毫米圓洞篩網篩選得到。透過篩網的原料被稱作“破裂”然後稱重。

2。1。2。 Germination test

Germination ability was determined according to the Association of Official Seed Analysts

(Anonymous, 1981)。 Three replications of 100 seeds were placed in presoaked germination paper

and were then placed in a seed germinator at 251C for 7 days。 After 7 days, the percentage of seeds germinating normally was recorded。

2。1。2 發芽力檢測

發芽能力是按照官方的種子專家學會去定義的。經過3次流程的100顆豆種被放置在發芽試紙上預浸,人後在發芽力檢測儀上以251C的溫度放置7天。 7天之後, 發芽種子的比例被記錄下來。

2。1。3。 Seed vigor

The seed vigor tests were conducted according to the International Seed Testing Association

(ISTA) method (Anonymous, 1985)。 Sheets of paper towel with 350 seeds were kept in a seed

germinator at 251C for 7 days。 After 7 days, the lengths of germinated seedlings were measured in

centimeters。 The vigor index was calculated as vigor index ¼ 1 NX germination ð%Þ seedling length ðcmÞ; where N is the number of seeds that germinated。

2。1。3 種子的活力

種子活力的檢測是按照國際種子檢測協會的步驟操作的。350顆豆种放在紙巾上,在種子發芽力檢測儀器內以251C的溫度儲存7天, 7天之後, 以釐米為單位去測量種芽的長度。活力指數是按照vigor index ¼ 1 NX germination ð%Þ seedling length ðcmÞ; where N is the number of seeds that germinated。(此處由於有亂碼, 無法翻譯)

2。1。4。 Accelerated aging

This test was used to predict the storage potential of seed。 It combines the stresses caused by

high temperature and high humidity to which seed maybe exposed。 It is expected that the seed

lots which record a higher level of germination in the accelerated aging test can be stored for a

longer period than others。 Two replications of 50 seeds were kept in perforated plastic boxes。

These boxes were kept at 401C and at 100% relative humidity(r :h:) for 96 h。 The germination of

these lots was recorded as outlined by the ISTA (Anonymous, 1985)。

2。1。4加速老化

這個檢測是用作預告種子的儲存潛力的。 它包括也許種子露天放置時,由高溫度和高溼度造成的作用。人們預計在發芽力檢測中有高記錄的那批種子能夠在加速老化測驗中比其它的種子儲存的更久。經過2次流程的50顆種子儲存在穿孔的盒子當中。這些盒子被放置在401C溫度及100%相對溼度中96個小時。這批的發芽力被ISTA作為要點記錄下來。

2。2。 Determination of moisture content

The standard oven method outlined by the ISTA (Anonymous, 1985) was employed。 Three

replications of 10 g seed were kept in a hot air oven at 1021C for 24 h。 At the end of this period, the samples were transferred to a desiccator for cooling。 The samples were then weighed and moisture content calculated on a dry mass basis。

2。2 含水量的定義

ISTA大綱中的標準加熱程式被引用到這裡。經過3次流程的10g豆種被儲存在幹烤箱中以1021C的溫度放置24小時。 在檢測最後, 樣品被轉移到乾燥器中冷卻。然後樣品稱重,並計算含水量,按照折幹計算。

2。3。 Evaluation of damage due to free-fall

To determine the effect of height of fall on the seed quality, three replications of 100 seeds,

drawn from each treatment, were dropped from a height of 0。5, 1。0, 1。5, or 2。0m on to a cement

floor or a galvanized iron floor。 The dropped seeds were tested for germination and vigor as

before。

2。4。 Statistical analysis of data

The data collected during the experiments were analyzed using ANOVA (Anonymous, 1992) to

study the effects of m:c:; process stages and heights of free-fall on the parameters of seed quality。

The differences in means were examined using the Tukey test of significance。

2。3 由自由下落造成損失的評估

為了確定下落高度對種子質量造成的影響, 經過3遍流程的100顆種子, 分別從0。5, 1。0, 1。5, 2。0米處下落到水泥地或者鍍鋅鐵板上,象以前一樣,下落的種子被檢測種子發芽力以及活力。

2。4資料統計分析

使用ANOVA分析了在實驗當中所收集的資料,研究了含水量,加工平臺以及自由下落的高度引數在種子質量方面的影響。檢測方式的差異已被Tukey test of significance。驗證。
