Chemotropic Growth of Clivia and Crinum Pollen Toward Pistils as Influenced by Calcium Action
|

Abstract
|
|
|
Pollen from Clivia miniata and Crinum asiaticum were grown either in artificial media containing 10% sucrose, 100 ㎎/ℓ boric acid and 1% bacto-agar or in calcium-supplemented media in order to study chemotropic response of pollen toward stylar segments of the same flower.
For either pollen tubes exhibiting tropic growth toward the stylar part, growth against the style or inconsistent directional growth, all resulted in demonitrating enhanced tube growth with calcium, thus the tropism became more indicative and striking than when without calcium in the media.
Therefore concluded that calcium does not play a role of determining factor in directed pollen-tube growth, namely pollen chemotropism, but merely promotes pollen-tube growth.
