Other claims from this paper (9)
- Intervention effect Moderate boron deficiency suppressed and delayed tassel emergence and anthesis.
- Observation Boron deficient stamens often lacked sporogenous tissue and had staminode or appendage form.
- Observation The abnormal stamens lacked or had branched vascular supply.
- Observation Apparently normal stamens in deficient plants failed to dehisce.
- Intervention effect Boron deficiency decreased pollen production, pollen size and pollen germination.
- Observation Marginal boron deficiency caused poor pollen germination without foliar symptoms.
- Observation Marginally deficient pollen had low catalase, acid phosphatase and starch phosphorylase activity.
- Observation Marginally deficient pollen had low invertase activity.
- Observation Marginally deficient pollen had high ribonuclease and amylase activity.
