| Abstract |
The high stalk weight sugarcane cultivar has a special mechanism to obtain greater
growth, which was inherited from its parents. Thus far, comparisons of the high stalk weight sugarcane
cultivar growth with its parents and cultivars with a low stalk weight have never been reported.
The purpose of this research was to reveal the growth mechanism of the high stalk dry
weight cultivar KK3 by comparing its physiological, anatomical, and morphological traits to those
of a low stalk dry weight cultivar (UT12) and their four parental cultivars under hydroponic conditions.
Their growth characteristics were evaluated at 15-day intervals from 30 to 90 days after planting.
The root traits were measured at 2 months after planting (MAP), whereas the anatomical and
physiological parameters were collected at 3 MAP. Biomass was recorded at 1, 2, and 3 MAP. KK3
had similar anatomical root traits to its female parent, whereas it had similar aboveground morphological
traits to its male parent. The comparison between UT12 and its parents revealed that almost
all its root anatomical traits were similar to the female parent, but it did not differ in leaf anatomy
and root system size. Some physiological traits of KK3 were not different from those of its parents.
In contrast, the net photosynthesis rate (PN), height, tiller number, stem dry weight, and stomatal
density of UT12 were lower than those of its parent. For KK3, its small root stele and vessel size and
high root length, surface area, and volume supported water uptake. The increase in stomatal density
and decreased stomatal pore length may be appropriate characteristics for reducing water loss in
this drought-resistant cultivar. Furthermore, KK3 exhibited a high water use efficiency (WUE) to
promote biomass accumulation and growth despite its low transpiration and photosynthesis rates.
This basic knowledge will be useful for selecting the parents based on their characteristics to create
new sugarcane cultivars with a high stalk dry weight for drought stress during the early-growth stage
breeding programs and predicting their performance. |
