The worlds biggest seed世界上仅次于的种子The secret behind the worlds largest seed is leaves that serve as good gutters. During rains, they channel lots of water and nutrients right to the plants thirsty roots.世界上仅次于的种子分解的秘密在于这种植物的叶子在大雨时候变成运输管道将大量水分及营养载运到植物饥渴的根部。Coco-de-mer palms (Lodoicea maldivica) produce these monster nuts, which are a type of seed. The biggest can tip the scales at up to 18 kilograms (roughly 40 pounds). Thats about as much as a 4-year-old boy. Yet the palm outperforms all other plants - at least in seed heft - with a below-poverty diet. These plants grow wild on nutrient-starved, rocky soil on just two islands in the Seychelles. (Theyre part of an arc of some 115 islands in the Indian Ocean, off of the East Coast of Africa.)海椰子树上会长出有这种粗壮坚果,实质上这是一种种子。仅次于的可重达18公斤(大约40重达),大约为一个四岁男孩的体重。

叶子

此外这种棕榈树比不上其他一切树种,最起码它能以很少的给养孕育出出来比较较小的种子。这些树根只生长在非洲塞舌尔群岛中的两个小岛上,虽然其扎根生长的土质是岩石类营养匮乏土质,但他们还是可怕的生长着。

生长

(这些树根也是非洲东海岸印度洋上由115个岛屿构成的弧形中最重要的一部分。)Christopher Kaiser-Bunbury works for the Seychelles Islands Foundation. Despite a scarcity of nutrients to fuel its growth, a palm forest is magnificent - its like a dinosaur could come around the corner, he says. Winds can jostle hectares (acres) of stiff leaves. This makes a sound he describes as crackling.Christopher Kaiser-Bunbury在塞舌尔群岛基地工作。尽管可供其生长的营养缺乏,但这些棕榈树森林长势依旧壮丽。就像知道从哪不会冒出来一只恐龙一样,他这样形容道。

若有风横过这些树根的树叶时,他不会听到噼里啪啦的响声。Nitrogen and phosphorus are two natural fertilizers - nutrients - that these (and other plants) need. There isnt much of either on the islands where these palms grow. So the plants are frugal. They sprout fronds using only about one-third the nutrients needed by leaves of 56 neighboring species of trees and shrubs. Whats more, coco-de-mer palms scavenge a lot of the nutrients shed in their own dying leaves. These trees can reuse 90 percent of that prized phosphorus from the fronds its about to drop. Thats a record for the plant world.氮磷是含有营养物质的两大天然肥料,于是以为这些树所须要(其他树种也某种程度必须)。然而在这些树根生长的地方才是缺乏这两种肥料。

营养

因此这种植物在营养用于方面很节约。比如幼苗宽叶时,他们意味着消耗1/3的营养,为周围56种树木和灌木的叶子生长所须要。此外,海椰子棕榈树还可利用将要掉下来的树叶上的营养物质,重复使用90%落叶上的磷。这是植物界中的一项纪录。
