Polyploidy induction and in vitro bulb propagation of lilium oriental hybrids 東方百合多倍體誘導及種球繁育的研究
Autopolyploids often have larger cells than the parent plants but are morphologically very similar 同源多倍體通常比它們父(母)本的細胞大,但形態(tài)上相似。
It is extraordinarily important to select tetraploid lines for breeding sugar beet polyploid varieties 摘要四倍體品系選育是甜菜多倍體育種不可缺少的重要環(huán)節(jié)。
Purpose : to explore the technique of induction of polyploidy in isatica indicago by colchicine treatment 摘要采用直接浸漬和加入培養(yǎng)基法對菘藍種子進行誘導,探討秋水仙堿誘導菘藍多倍體的方法。
Since the first tetraploid was obtained in 1939 , polyploidy breeding has always been the focus of watermelon breeding 從1939年獲得第一個四倍體西瓜以來,多倍體育種就一直是西瓜育種的一個熱點。
Allopolyploidy a type of polyploidy involving the combination of chromosomes from two or more different species 異源多倍體:兩種或兩個以上的不相同的物種雜交,雜種經(jīng)染色體加倍形成的多倍體類型。
Alternatively , like allopolyploids , they may arise by the nondisjunction of chromatids during the mitotic division of a zygote 與異源多倍體相似的是,它們也是在有絲分裂中合子的染色單體不分離形成的。
Autopoly - ploids may arise from the fusion of diploid gametes that have resulted from the nondisjunction of chromosomes at meiosis 同源多倍體通常可能來自在減數(shù)分裂過程中染色體不分離導致的二倍體融合。
