Low concentration of NaCl solution could promote the growth on the shoot of seed germination. The growing length of roots and shoots of two halophytes treated by 100 mmol·L~(-1) NaCl reached the highest and the growing condition on shoots was best. Then some physiological and biochemical parameters including the content of Na~+, K~+, Ca~(2+), proline and plant leaf tissue water potential, the assays of membrane lipid peroxidation and antioxidant enzymes were determined with the two halophytic plants on salinity.

研究工作首先对盐爪爪和盐穗木在种子萌发阶段的耐盐性进行了比较研究，表明盐爪爪和盐穗木都是很耐盐的盐生植物，在种子萌发期，盐穗木比盐爪爪更耐盐；NaCl和等渗的聚乙二醇对种子的萌发都产生抑制作用，且PEG的抑制程度大于等渗的NaCl。

植株部位棉酚的存在是棉株自身防御病虫危害的重要途径，同时也是由于棉酚的存在，致使棉子中棉子油和棉子蛋白不能用于人畜食用。

Firstly, an invasive species must be invasive enough in itself or has some biological distinction, such as quantitative and qualitative differences in the genome, or patterns of recombination. Secondly, to invade successfully, a new environment for an invasive species must be invasible, and this we may call the ecological basis of invasion. An invasive species may need to establish new interactions with other species, especially those mutualistic relations such as animal related pollination, seed dispersal by animals, mycorrhizal fungi, and symbioses between plants and nitrogen fixing bacteria.

首先从其自身来说，需要有足够的入侵性，这可以认为是入侵种的生物学基础，可能表现为具有多倍性、一定的遗传变异、杂合性或表型可塑性，以及不同的交配系统等；其次一个物种的入侵成功还取决于入侵生境的可入侵性，这可以认为是入侵种的生态学基础，而新的种间关系的形成，尤其是入侵种与其他种类的互惠共生关系的建成是关键。

The finding dovetails with the paleobotanical record, which shows that the flowering plants had just invented a veritable cornucopia of new fruits, flowers, gums and nectars with which to entice pollinators and seed dispersers.

这一发现正与古植物学记录相吻合，当时开花植物刚发展出十足丰盛的新式果实、朵、脂、蜜，藉此吸引授粉者和种子传播者前来。
