Abstract
Germination expts. with gram (Cicer arietinum) seeds soaked for 24 hrs. in water containing 3 ml. of crude filtrate (Polyporin) showed distinct retardation of germination when compared with a control soaked in water; even the seedlings were fewer in number and shorter in length than those of the control. Rings were cut from the outer cortex of guava branches (Psidium guajava) and the exposed surfaces were smeared with (1) crude Polyporin for 24 and 48 hrs., respectively, being finally wrapped with moist cotton wool. Other branches similarly treated were covered with cotton wool soaked in (2) dist. water and in (3) 4% glucose, pea-decoction, and salts. In the case of (1), Polyporin was washed out with dist. water after 24 and 48 hrs., respectively, and the regions were covered with moist cotton wool. All treated parts of branches were watered daily with dist. water. In 26 days, 2 roots formed from the branch treated with Polyporin for 24 hrs., and 6 roots from that treated for 48 hrs. The roots were strong and healthy. No root formation occurred in cases of (2) and (3). Root development was also obtained from Eugenia jambos stems treated with Polyporin for 48 hrs.
