宮粉羊蹄甲x紅花羊蹄甲=洋紫荊?

若果再次雜交,能否使洋紫荆進行有性繁殖?

不能，因為父母並非同一物種，所以子代沒有繁殖能力

就算豆科都吾得?

是不是所有雜交種都是這樣?

同科同屬但唔同種都唔得

同種雜交就可以, 例如西施狗同北京狗, 大家係同種, 生出黎就可以再有子代

根球係無性繁殖, 佢地應該結唔到果的, 有錯求指正

they use seed not their 根球
they HYBRID themselves

唔同種可以雜交，但雜交得出的子代不能再有子代

例如馬+驢=騾，但騾+騾就出唔到騾

why do you think that hybrid plants are not normal/native/false?
bauhinia x blakeana was first identified as a natural hybrid and is then artificially maintained, so it is now considered as an artificial cultivar, but that doesn't mean that it is not a normal plant or a false plant ...

anyway, according to a 2005 research, the causes of sterility in bauhinia x blakeana are obscure
it has the same diploid chromosome number as its parental species, but the slight difference in the karyotypes might have contributed to the sterility

there is no clear-cut methods to determine whether a hybrid will be fertile or not, and hybrid in animal cases cannot always apply to plants

nature is complicated and science still has much to learn
