A small or secondary spike, characteristic of grasses and sedges, bearing one or more florets and usually subtended by one or two bracts.


1. (Botany) botany the unit of a grass inflorescence, typically consisting of two bracts (glumes) surrounding one or more florets, each of which is itself surrounded by two bracts. See lemma1, palea

There are two types of flowers, and usually only one of these, known as the sessile spikelet (SS), is fertile, according to the study.
At this stage, temperatures below 17[degrees]C negatively impact pollen grain formation (SOSBAI, 2014), resulting in increased spikelet sterility in this period (Baruah et al.
17 cm), tillers number m-2, spikes number m-2, spike length, number of spikelet spike-1, number of grains spike-1, 1000-grain weight, grain yield, straw yield, biological yield and harvest index, respectively, in both seasons followed by Zn foliar application followed by Mn foliar application followed by Fe foliar application then Cu foliar application.
The maximum spikelet per spike was found where the wheat was sown @ 150 kg ha-1 that was also comparable with 125 kg ha-1 treatment while the minimum was in 100 kg ha-1 (Table 2).
After harvest, spikelet per main spike (SMS, the 10 main panicle average the value), grain number per spike (GrNo/S, the average value of the random 10 ears), sterile spikelet number (SSNo, the average value of the random 10 ears), thousand grain weight (TGW, 1000 grain weight), harvest index (HI) and grain yield per plot (GY/P) were investigated.
1) may consist of many spikelets arranged in a complex branching system, or a few spikelets or even a single spikelet (Haines & Lye, 1983, Vegetti & Tivano, 1991a; Vegetti, 1992, 1994, 2002, 2003; Heinzen & Vegetti, 1994; Goetghebeur, 1998; Browning & Gordon-Gray, 1999; Camelbeke, 2002; Guarise & Vegetti, 2007; Ahumada & Vegetti, 2009; Reutemann et al.
The grain yield, spikelet sterility, number of grains per panicle, plant height, number of days to flowering, and 100-grain weight were evaluated by conventional methods.
1]s and subsequently, the screening based on pollen and spikelet sterility to infer the male parent to be restorer or maintainer which is tedious and involves extra season.
Spikelets solitary, sessile, compressed, elliptic, 3-5 mm long; each spikelet has 3-9 fertile florets.
Spikelet production is influenced by nutrient uptake, especially nitrogen.
The modes of damage to wheat crop were, loopering of tops of wheat plant, poor pollination/fertilization, shattering of spikelet in early sown wheat crop, mechanical injury to Flag leaf and stem of wheat.
