The experiment was conducted during Kharif 2020 and 2021 at Jawaharlal Nehru Krishi Vishwavidyalaya, Jabalpur, Madhya Pradesh, India. A total of 103 accessions including 03 checks were assessed observations recorded for ten traits viz., days to flower initiation, 50 % flowering, maturity, plant height (cm), number primary branches per plant, secondary capitula seeds capitula, 1000 seed weight (...

Chicory (Cichorium intybus L.) seed production includes sorting to remove foreign materials and non-viable seeds. A machine vision system was developed to monitor the fluorescence in order to detect the immature chicory seeds. It comprised a monochromatic light source, a highpass filter and a monochromatic CCD camera sensitive to red and infrared. With this device, blue light reflected by the s...

The fruit harvest at physiological maturity of seeds is a globally accepted practice. This method has been traditionally practiced in horticultural crops where quality and vigorous seedlings are ensured for cultivation the species. assessment seed forest fruits seldom as biochemical studies tropical little attempted. Since recalcitrant behavior among species increasing, maintenance viability lo...

Carex divisa is a patrimonial rhizomatous species and acts as an important component of grazed wet permanent grassland on the French Atlantic coast. This study treated three storage regimes (wet-cold, dry-cold and dry-warm), burial in soil, fluctuating temperature and salinity on seed germination of C. divisa. The seeds were dormant at maturity. No seed germinated after 2 and 6 weeks of dry sto...

Crude oils and source rocks from the northern and offshore Niger Delta basin, Nigeria, have been characterized by gas chromatography-mass spectrometry in terms of their origin and thermal maturity based on the distribution of chrysene and its derivatives. The crude oils and source rocks were characterized by the dominance of chrysene over benzo[a]anthracene. 3-methylchrysene predominated over o...

Wheat is the main vital cereal crop in Mongolia (Triticum spp.) The size of seed one important feature quality. It directly related to plant growth, yield, market factor and harvest efficiency [1]. Equally are shape seed. middle spike ripens fast, after which upper lower parts ripen. Even though seeds part fill up at same time as section spike, later. Seeds have good filling bigger too. Moreove...

The function of stamen dimorphism in the breeding system of the alpine shrub Rhododendron ferrugineum was studied in two populations in the French Alps. This species has pentameric flowers with two whorls of stamens: an inner whorl of five long stamens and an outer whorl of short stamens. We studied the development of stamens from buds to mature flowers (measurement of the filament, anther, and...

Barley, Hordeum vulgare L., is well adapted to subarctic Alaska growing conditions, but little is known about its response to grasshopper defoliation. A field experiment was conducted to study dry matter and grain yield in response to a combination of grasshopper defoliation and weeds in 2002 and 2003 near Delta Junction, AK (63 degrees 55' N, 145 degrees 20' W). Barley plants at third to fourt...
