EVALUATION OF MENDOK AND DALAPON AS MALE GAMETOCIDES AND THEIR EFFECTS ON GROWTH AND YIELD OF LINSEED

P. N. RUSTAGI; H. Y. MOHAN RAM New Phytologist 1971. doi:10.1111/j.1469-8137.1971.tb02517.x

Other claims from this paper (14)

Intervention effect Mendok was slightly more effective than Dalapon as a male gametocide in linseed.
Intervention effect Treated linseed plants showed profuse branching, enhanced vegetative growth and heavy flower production.
Intervention effect Flowers of treated linseed plants became progressively smaller.
Intervention effect Flowers of treated linseed plants gradually closed.
Intervention effect Production and germination of seeds were considerably reduced in treated linseed plants.
Intervention effect Gamete fertility was reduced by the gametocide treatments.
Observation Male sterility was induced in two forms: developmental and functional.
Observation Developmental male sterility was characterized by fully or partially barren anthers and non-viable pollen.
Observation Pollen non-viability showed rhythms interspersed with periods of restored viability.
Observation Functional male sterility resulted from lack of anthesis, fusion and non-dehiscence of fertile anthers and agglutination of pollen.
Observation Tapetal cells in anthers of undersized flowers stayed highly vacuolate and persisted to the mature pollen grain stage.
Observation Microsporangia differentiated on petals.
Observation Treated plants showed toxicity symptoms of chlorosis and slight to severe burning of young leaves and flower buds.
Recommendation Neither Mendok nor Dalapon can be used as a specific male sterilizing agent in linseed.

Other claims from this paper (19)

Observation Plant dry weight ranked 25°/20° above 30°/25° and 17°/12° with a 5°C daily range.
Observation Plant dry weight ranked 25°/15° above 30°/20° with a 10°C daily range.
Intervention effect At the same day temperature, nights 10°C cooler increased plant dry weight versus nights 5°C cooler.
Intervention effect Gradual and sudden temperature changes produced little difference in dry matter production.
Observation Outdoor plant dry weight was approximately that at 25°/20°.
Observation Seed yield was greatest at 25°/15° and 30°/20° and very small at 17°/12°.
Association Pod and seed number tended to increase with temperature under a 5°C daily range.
Observation Pod and seed numbers were nearly the same at 25°/15° and 30°/20°.
Intervention effect At the same day temperature, a 10°C daily range gave greater pod and seed numbers than a 5°C range.
Observation Outdoor pod and seed numbers were similar to 25°/20°.
Observation The 100-seed weight was greatest at 25°/20° and extremely small at 17°/12°.
Association N, K, TAC, and seed oil accumulation tracked dry matter accumulation across temperatures.
Association P accumulation tended to rise with temperature.
Observation At maturity, N, P, K and TAC accumulated mainly in seeds, Mg+Ca in pod shells, and Fe and Na in roots.
Association Seed Fe and oil concentration tended to rise with temperature.
Association Palmitic, stearic and oleic acids tended to increase with temperature.
Association Linoleic and linolenic acids tended to decrease with temperature.
Association Larger seeds ripened outdoors or at 25°/20°, 25°/15°, or 30°/20° had higher germination percentage.
Recommendation The authors judged 25° to 30° day temperature with a 10°C daily range optimal for ripening performance.
