Rashin zinc
Alamomin karancin zinc sun hada da:
- Chlorosis – yellowing na ganye; Sau da yawa masu haɗa harshe; A wasu nau’in, ƙananan ganye sun fi shafa, amma a wasu, duka sabo da tsofaffin ganye suna chlorotic.
- Necrotic spots – mutuwar nama ganye a yankunan chlorosis.
- Ganyen tagulla – Yankunan chlorotic na iya zama tanned.
- Jinkirin girma shuka – zai iya faruwa a sakamakon raguwar haɓakar girma ko raguwa a cikin internode.
- Dwarf ganye – ƙananan ganye waɗanda galibi suna nuna chlorosis, necrotic ko tan spots.
