Chromosome observation of the male sterile line and fertile line, parents of hybrid combination and F1 indicated that the chromosome number of the male sterile line is the same as that of fertile line 2n=2x=24; Pollen parent (Tagetes putula PHBO029) is tetraploid 2n=4x=48; the F1 is triploid 2n=3x=36 with hybrid vigor.

通过对不育系、正常可育系以及杂交组合父母本、子一代的染色体数目观察发现：万寿菊雄性不育系的染色体数目与正常可育系相同，均为2n=2x=24；孔雀草PHBO029为四倍体2n=4x=48，它与万寿菊不育系杂交、其杂种为具有杂种优势的三倍体2n=3x=36。

And according to this book, Tiger Lilies resist hybridizing because they are a rare "triploid" that can't be made to change their spots.

而根据这本书，老虎百合抵制杂交，因为它们是一个罕见的&三倍体&无法作出改变的地方。

5The different intercrops had different effects on soil physic-chemical characteristics. Soil bulk density、soil organic matter and soil available nitrogen were improved significance by intercropped cotton.

不同间作物对林木高生长没有产生显著差异，但对胸径生长的影响达到了显著性差异水平，间作棉花在第一年促进了三倍体毛白杨胸径的生长。

Genetic models including genetic effects and genotype × environment intera ction effects for quantitative traits of triploid endosperms in cereal crops were used to analyze miling quality traits of indica rice in different environments.

采用包括遗传主效应和基因型与环境互作效应的种子三倍体遗传模型，分析了不同环境条件下籼稻稻米碾磨品质的遗传特性。

Pinus sylvestnis var. mongolica Litv. and poplar were used as test materials in studies of the ACQ preservative performances against green woods mold. By comparing weight loss of test samples after decay caused by green woods mold, the influences of ACQ type, concentration, and wood type on the ACQ preservative performance were investigated. The effects of pH and additives on anti-loss performance of ACQ were also studied by comparing weight loss percentage after sample extraction.

以樟子松和三倍体毛白杨为试材，ACQ为防腐剂对绿色木霉进行防腐性能研究，通过比较试样经绿霉菌腐蚀后的质量损失率来分析ACQ类型、浓度、树种类别对ACQ防腐性能的影响；并比较试样经抽提后质量损失率来分析酸碱度，助剂对ACQ抗流失性能的影响。
