石栗結果 candlenut

石栗大概是上一代廣泛採用的種植樹,因為生長快速,樹幹挺直高聳,樹冠濃密,又能扺受強風和耐寒,最好遮蔭和觀賞。但現在新式的市區設置中,應該少見選取石栗,原因其一聽來比較可笑,全怪果子累事。果子堅硬,成熟跌下砸人頭,執事人怕惹麻煩,不種為妙。另外,去年,在香港及廣州都有報導指某些植物會誘發癌症,其中包括石栗。說得是「促癌植物」含有過多氧化鐵,會令人體產生自由基,令壞細胞擴散,成為誘發癌症元兇。(資料來源:東方日報)

我「包坳頸」,反而期待石栗果敲頭。畢竟生在市區,感受果子的自然規律帶來的,該是彩頭吧!

candlenut tree is one of the common planting trees, because it grows rapidly, it stands tall and straight with a dense canopy. it is resistant to strong wind and cold weather. what a great shade and ornamental tree.

it is however losing popularity as its trademark, the candlenuts can hurt people when they mature and fall down. there was also study saying that this tree along with some other plants contain too much iron oxide, which will cause human body to generate free radicals and spread bad cell.

but i just love this good old kind of tree. it produces beautiful leafs and multi-talented nuts. it is an enriching sensation seeing bundles of round big nuts hanging high.

 

按維基百科說,石栗果含油量達65-70%,榨取的油可供製作油漆、肥皂、蠟燭等工業的原料,及生物燃料供汽車直接使用,還可用來做木材防腐、燈油燃料及蠟染工藝。印尼人會將處理過的堅果拿來煮咖喱。新鮮的堅果含氫氰酸與微量毒蛋白質,有毒。

在網上搜尋資料,有趣地尋覓到香港的學校都載有他們校園中的石栗。香港培正小學荃灣潮州公學何文田官立中學,以及惹人懷念從前在香港大學的一顆。

some may know that candlenut is the state tree of hawaii. it is interesting to know that it is not native to hawaii (but malaysia and polynesia). here are more information about the tree from magical-hawaii.com:

in 1930, the official tree of the territory of hawaii, was the coconut palm, however in 1959, it was changed to the candlenut tree.

the tree has white flowers and round pods. the trees grow to a height of 15-25 meters. the leaves are pale green. the nuts, which have a very hard shell, are slightly poisonous when raw, and are flammable – like candles.

the ancient hawaiians used kukui nuts to make torches, which they used to light the night. these nuts have a very high oil concentration and burn for a long time. the hawaiians would put several on a stick and light the first one on fire, letting it burn down the line of nuts . this also became a way to tell time, or how much time has passed.

kukui nuts are traditionally used to make leis and the oil is used to make woods preservatives, varnishes and soap. the oil is also great for the skin. it can be used as a natural moisturizer. it soothes sunburns, and is beneficial for many skin problems.
