试验品种为Bruinsina Wonder,播种在直径50毫米的塑料钵中,在25℃温度下发芽,发芽后五天移入人工气候室。昼温为25℃,夜温分别为25、21、17℃以及昼温为21℃,夜温分别是21、17、13℃等几个组合。光照由Philipo JL57 40W荧光灯供给。分人工光照8小时(8FL)、16小时(16FL)和自然光照8小时(8DL),以及在25℃温度下人工连续光照24小时(24FL)等几种。日照量8小时的自然光是113Wm~(-2),人工光照是29Wm~2。每天的8DL、8FL、16FL、24FL的光照量分别是3.25、0.84、1.67和2.51MJm~(-2)。每1～2周取4个单株调查生长速度。在试验中追肥和调换钵子(直径90、150毫米)。根据每个时间的自然对数算出生长参数。发芽后60天内,如果每天的日射量多叶数就增
The test variety, Bruinsina Wonder, was seeded in a 50 mm diameter plastic bowl and germinated at 25 ° C. Five days after germination, it was moved to the climatic chamber. The daily temperature was 25 ℃, night temperature was 25,21,17 ℃ and day temperature was 21 ℃, night temperature was 21,17,13 ℃ and other combinations. Lighting is supplied by the Philipo JL57 40W fluorescent lamp. The artificial lighting 8 hours (8FL), 16 hours (16FL) and natural light 8 hours (8DL), and 25 ℃ temperature artificial continuous light 24 hours (24FL) and several other. The natural light with 8 hours of sunshine is 113Wm ~ (-2) and the artificial light is 29Wm ~ 2. The daily illumination of 8DL, 8FL, 16FL and 24FL were 3.25,0.84,1.67 and 2.51MJm -2, respectively. Every 1 to 2 weeks to take four plants surveyed growth rate. In the test dressing and exchange bowl (diameter 90,150 mm). The growth parameters are calculated from the natural logarithms of each time. 60 days after germination, if the amount of daily sun-light on the number increased
