Title

Fertilization and early embryo development in the cross between Triticum aestivum and Dasypyrum villosum

Zhou Yong Xi'nan nongye xuebao 1999

Other claims from this paper (8)

Observation Dasypyrum pollen germinated normally on wheat stigmas and pollen tubes entered embryo sacs.
Observation Double fertilization with embryo and endosperm occurred in 13 81% of observed ovaries.
Observation Only endosperm formed in 4 76% of observed ovaries.
Observation Total fertilization rate was 34 76%.
Observation Total embryo formation rate was 30 00%.
Observation Endosperm developed more slowly than embryo and was abnormal, absent or later vanished.
Mechanism Abnormal or missing endosperm made viable mature seed production very difficult.
Recommendation Early embryo rescue at 7 11 days after pollination could greatly increase hybrid plant survival.

Ernest Spitzer; John N. A. Lott Canadian Journal of Botany 1982. doi:10.1139/b82-175

Other claims from this paper (5)

Observation Two types of protein bodies occurred across the studied genera.
Observation One protein body type had a proteinaceous matrix and globoid crystal inclusions.
Observation The other type had a matrix and calcium-rich crystal druses.
Observation The two protein body types did not occur in the same cell.
Observation Embryo protein bodies were smaller, more numerous per cell and often had a flocculent matrix.

Tetiana Rozhkova; Alla Burdulanyuk; Valentyna Tatarynova; et al. Ecological Engineering & Environmental Technology 2024. doi:10.12912/27197050/186126

Other claims from this paper (13)

Observation Macroanalysis identified wrinkled, small, and black point winter wheat seeds.
Association Abnormal seed abundance varied with growing conditions, cultivation place, and fungicide spraying.
Observation Polissia had the maximum number of substandard seeds, dominated by black point.
Observation In the Forest-steppe, substandard seeds were most abundant in 2022 and small seeds prevailed.
Observation Seeds with a black point were usually mature.
Intervention effect Spraying cinnamon essential oil increased black point appearance.
Intervention effect Spraying fennel essential oil increased black point appearance.
Observation Externally healthy Bohdana seeds germinated better than abnormal seeds under cold and wet conditions.
Observation Abnormal seed germination differed inconsistently between years.
Observation Under favorable conditions, black point seeds showed higher germination and seedling development indicators than healthy seeds.
Observation Under low temperature, healthy seeds germinated better than black point seeds.
Observation Healthy seeds initially produced faster developing seedlings.
Observation On the last two measurements, seedlings from black point seeds grew faster.
