The yield loss simulation (YLS) and the MACROS LIQ.CSM models were used to simulate the effect of stem borer damage at a detillering rate of 5, 15, 30, 60% at vegetative, panicle initiation and grain filing stages, on yield of rice cultivar?s Ratna. This stem borer damage during vegetative and panicle initiation stages was not simulated appropriately by both the models. Relatively MACROS simul...

Gaseous hormone ethylene has diverse effects in various plant processes. These processes include seed germination, plant growth, senescence, fruit ripening, biotic and abiotic stresses responses, and many other aspects. The biosynthesis and signaling of ethylene have been extensively studied in model Arabidopsis in the past two decades. However, knowledge about the ethylene signaling mechanism ...

To investigate whether the regulation of abscisic acid (ABA) content was related to germinability during grain development, two cDNAs for 9-cis-epoxycarotenoid dioxygenase (HvNCED1 and HvNCED2) and one cDNA for ABA 8'-hydroxylase (HvCYP707A1), which are enzymes thought to catalyse key regulatory steps in ABA biosynthesis and catabolism, respectively, were cloned from barley (Hordeum vulgare L.)...

Phosphorus fertilization or pruning as sole practice has been established to enhance tomato yield. However, there is a dearth of knowledge when both practices are combined. Under potted experiment, two varieties (Tomato 82-B and Local) were subjected 13 treatment combinations phosphorus between June September, 2021 in garden situated at Ilorin, Nigeria. In varieties, plants receiving 30 kg P/ha...

iran is widely drought prone, considering its semi-arid climate. eleven wheat cultivars differing in yield potential and drought resistance were employed to determine the possible relationship among grain filling rate and duration, stem reserves remobilization and grain yield under either irrigated (ir) or non-irrigated (nir) conditions at gerizeh research station in sanandaj for a duration of ...

We describe a simple and cost effective method for screening the effects, of stem extract along with biogenic nanoparticles synthesized from Cissus quadrangularis stem extract, on Vigna radiata seed germination and root length. At higher concentrations (200 μl to 300 μl) of stem extract (1 2.5 g ml ) germination was completely inhibited. The inhibition was dose dependent. Synthesized nanopartic...

The composition of cell walls in cereal grains and other grass species differs markedly from walls in seeds of other plants. In the maternal tissues that surround the embryo and endosperm of the grain, walls contain higher levels of cellulose and in many cases are heavily lignified. This may be contrasted with walls of the endosperm, where the amount of cellulose is relatively low, and the wall...
