一、开花结果的生理生态 (一)开花、受精的过程如外界条件适合,已成熟的番茄花蕾,即可开花。将要开花前,花冠迅速生长,先是各个萼片的顶端分离而向外侧开张,紧接着每个花瓣的顶端也各自分离向外侧张开而开花了。始花后大约经过止天,萼片与花瓣同时向下端开裂而完全张开于外侧。开花后花瓣仍继续迅速生长。始花时,花瓣比萼片略短些,甚至长短一样,但开花后,大约经过一天,花瓣的长度就达到了萼片的1.5～2倍左右。开花时花瓣的颜色呈淡黄色,而后变浓,开花1天以后,成了深黄色。
First, the physiological and ecological consequences of flowering (a) flowering, fertilization process, such as the external conditions suitable, ripe tomato buds, you can flowering. Before flowering, the corolla grows rapidly. First, the tops of the sepals are separated and opened to the outside. Then, the top of each petal is also separated to open to the outside and flowering. After the beginning of the flowering after about only days, sepals and petals at the same time to the bottom of the crack and completely open in the outside. Petals continue to grow rapidly after flowering. When the first flowers, petals slightly shorter than the sepals, or even the same length, but after flowering, after about one day, the length of the petals reached sepals 1.5 to 2 times. Petals when flowering pale yellow color, and then thicken, flowering after 1 day, became a dark yellow.
