Distribution and Density of Vegetative Hydrilla Propagules in the Sediments of Two New Zealand Lakes [PDF]

, 1999
The distribution and density of hydrilla (Hydrilla verticillata (L.f.)Royle) turions and tubers in two New Zealand lakes were assessed by sampling cores of sediment from Lakes Tutira and Waikapiro each year from 1994 to 1997.

A study of tuberization in the potato plant. : V. A relation of the mother tuber to the plant growth and tuberization with plant growth.

Japanese Journal of Crop Science, 1951
Seed tuber in the potato plant relates very greatly in its growth and yield. Here the author observed a periodical relation of mother tuber to plant growth and tuberization. The experiments were carried out during 1947, 1948 and 1949 years. The results observed are as follows. 1.

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Innovative technologies for accelerated reproduction of initial seed material from in vitro micro plants on the biotechnological module AGM-60 [PDF]

BIO Web of Conferences
A biotechnological aerohydroponic module has been created for growing plants without using soil by creating a water-air nutrient medium in the root space, and a method has been developed for accelerated propagation and mass replication of improved potato

Effects of Seed Tuber Size and Planting Density on the Tuber Number and the Individual Tuber Weight of Plants Grown from Potato Microtubers in Fields

Japanese Journal of Crop Science, 2011
バレイショ採種における低増殖率を解決する一つの手段として，器内培養で大量に増殖したマイクロチューバー（MT）を種イモにする栽培（MT栽培）が検討されている．本研究では，MT栽培特性が異なる2品種を用いて，大きさの異なるMTを種イモとする試験，および異なる栽植密度の試験を，それぞれ3水準で行い，慣行の種イモ（CT）を用いる栽培（CT栽培）と比較した．MTの種イモの大きさ別の試験では，両品種とも塊茎肥大初期には小粒MT（0.3～0.49 g）を種イモとした栽培ほど塊茎数が少なかった．しかし，MT栽培で個数型となる農林1号では，収穫期において小粒MTを種イモとした栽培の塊茎数がCT栽培と同程度まで増加した．塊茎肥大初期の塊茎形質とそれ以降の塊茎数増加割合との間には有意な負の相関関係が認められ ...

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

The Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Thermal sum of potato plants and tuber sprouting [PDF]

Ciência Rural, 2017
ABSTRACT: This study aimed to determine the thermal sum of the different stages of development of potato plants to better understand its relationship with tuber sprouting. The potato clones SMIJ461-1, SMINIA793101-3 and SMINIA97145-2 and the cultivar Macaca were evaluated in spring and autumn crop seasons in Santa Maria and Julio de Castilhos, RS ...

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

The Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Differences in predominant collagen fiber orientation between dorsal and plantar trabecular bone tracts of adult mule deer calcanei suggest strain‐mode‐specific adaptation

The Anatomical Record, EarlyView.
Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,
